Foxconn Looking to Deploy 1 Million Robots (in China) Over Next 3 Years

Frida Humanoid Robot from ABB

News just broke on XinHuaNet (via Slashdot) that Foxconn, a Taiwanese company with more than 1M Chinese laborers on the mainland,  plans to deploy one million robots(!) over the next three years -- a 100-fold increase over current numbers.  This should serve as a wake-up call for the United States.  China already dominates in manufacturing; if they can capture the "new" flexible, light manufacturing space too, then the United States will be in dire straits (National Robotics Initiative or not).  One commentor on HackerNews suggests that the robots will be ABB's Frida. Of course this needs more substantiation, but ABB isn't exactly a newcomer to industrial robotics; the Swiss company has been around for ages.  Still, it would be mildly surprising if ABB wins out over all the competition (eg. Heartland Robotics) that are specifically trying to establish themselves as pioneers in "flexible, light manufacturing."  The future of robotics certainly looks interesting!

New Robotis Dynamixel Servos (MX-28) Sport 360-Degree Rotation and 4x Angular Resolution

MX-28 Robotis Dynamixel Servo

Robotis has just announced a new line of Dynamixel Servos: the MX-series, beginning with the release of the MX-28.  The MX-28 servo has some distinct improvements over its RX-28 brethren: 12-bit (0.088°) angular resolution (four times that of the RX), full 360° controlled rotation (rather than 300°), non-contact magnetic encoders (not subject to mechanical wear), etc. -- and all for about the same price (MX-28: $219.90 MSRP, RX-28: $200)!   Of note, the MX-28 is prominently featured as part of the new DARwin-OP humanoid -- the recent Nao competitor that Robotis created in collaboration with Virginia Tech's RoMeLa Lab.  Perhaps best of all... Hizook was selected as a beta tester for this new servo (probably owing to our  prominent coverage of the RX-series and our awesome cross-platform open-source Robotis software library).  We were impressed with the new MX-28 -- read on for details, including an exclusive look inside the new servo as well as a quick tutorial using the updated open-source drivers (in python, complete with ROS bindings).  

Highly Anticipated ICRA 2011 Talks: Low-Cost Arms, Helicopter Manipulation, and Ball Catching

Highly anticipated talks at ICRA 2011

ICRA 2011 kicks off in less than two weeks in Shanghai, China.  Unfortunately, I won't be attending -- I'll have to wait to see y'all at IROS 2011 in San Francisco come September.  However, I was browsing through the program and it looks like there are going to be a lot of great talks! A few that caught my eye: Morgan Quigley's low-cost 7 degree-of-freedom (7-DoF) series elastic actuator (SEA) arm for sub-$5k, Aaron Dollar's helicopter-mounted shape deposition manufacturing (SDM) hand,  and Rollin' Justin's fast reflexes to catch flying (tossed) balls... and these are just the talks that have videos posted online already (embedded below).  Eventually I'll get around to writing about all this cool research (after finishing my dissertation in a few months!) -- but for the time being, here's a quick scatter-shot overview.

Da Vinci Surgical Robot Whimsy: Plays "Operation" Board Game and Builds Paper Airplanes

Da Vinci Robot Playing Operation Board Game

Carol Reiley, a surgical robotics PhD student at Johns Hopkins' Computational Interaction and Robotics Laboratory, wrote in to share how they unwind after a long day of research.  She writes, "Here's a video of the Johns Hopkins Robotics lab playing the board game Operation on the $1.3M dollar (Da Vinci Surgical) robot. The video emphasizes the robot's precision and hand tremor reduction as well as how difficult Operation is to play, even with a robot. :-)" Fun, whimsical, and a bit meta.  Surgical roboticists seem to enjoy themselves; seems like just yesterday they were using the robot to make little paper airplanes or produce dance videos.

The Bilibot Project: A Low-Cost Robot Platform with iRobot Create, Kinect, and ROSified Computer

Bilibot Robot: Kinect atop an iRobot Create

Perhaps you remember Garratt Gallagher -- he's the ROS / Kinect hacker responsible for 30% of all entries in the recent Kinect / ROS 3D competition, in which he  won first place for Impromptu Buttons (his other entries such as Finger Detection, People Follower, Kinect Minority Report Interface, etc. were also quite impressive).  However  I want to introduce you to his most exciting project to date:  Bilibot.  Started in December and funded with $5,500 through KickStarter, the Bilibot Project is an open source effort to create an affordable robotics platform based on the iRobot Create, Kinect, and a computer pre-installed and pre-configured with Ubuntu and ROS.   The goal is to create a platform for hackers, enthusiasts, and researchers that works right out of the box without the (often daunting) challenge of installing and configuring Ubuntu and ROS.  Frankly, the $150 Kinect may be popular in the gaming industry, but it will completely revolutionize robotics -- it is an amazing sensor, and the Bilibot project aims to make it even more accessible. 

iPad and iPhone-Controlled Robot Toys

iPhone Controlled Robot -- ARDrone Robot Helicopter

I'm intrigued by several recent high-tech robot toys that provide an immersive, augmented-reality experience that is grounded in a real, physical robot.  Almost universally, these new toys are controlled by smart phones or tablet computers (eg. iPad / iPhone / iPodTouch or Android devices) and will likely be hacker / developer friendly.  They are becoming increasingly sensor-rich and often offer video feedback -- all enabled by the commoditization of robotic components.  For example, the Parrot AR.Drone is a quadrotor helicopter that enables UAV aerial dogfights.  Another is the forthcoming Orbotix Sphero, a simple robot ball that will presumably support many mini-games: like a real-life version of Super Monkey Ball or the best cat toy ever!  Yet another example for you hackers out there, Matt Might created an iPhone-based multitouch remote control for a Scribbler robot in just 6 hours and 200 lines of JavaScript / Python!

The Need for Low Cost Sensors in Robotics -- Holiday Edition

Kinect Depth Camera (RGB-D Camera)

This is a guest essay by Fred Nikgohar.  Fred is the CEO of RoboDynamics, makers of the TiLR robot which was recently featured in a New York Times overview of telepresence robots.  Fred argues that we've reached a watershed moment in robotics facilitated by cheap 3D sensors like Microsoft's Kinect (ie. PrimeSense RGB-D camera) -- that the Kinect provides a roadmap where "the best solution to complex, low-cost sensing (or actuation for that matter) is to take advantage of affordable, mass-produced components, complementing them with the innovative use of software solutions that benefit from constantly declining prices of computation."

iRobot AVA Telepresence Robot at CES 2011 -- One Step Closer to Robot App Stores

iRobot AVA Telepresence Robot

I would like to introduce you to iRobot's latest prototype: a new telepresence robot named AVA that was unveiled this week at the Consumer Electronics Show (CES 2011) -- see the video below.  Through AVA, iRobot intends to explicitly leverage the proliferation of tablets / smart phones and their associated app stores.  They intend to furnish actuation (mobile base, pan-tilt unit, telescoping linear actuator spine, etc.), a sensor suite (including sonar, laser, and a depth camera like Microsoft's Kinect), and basic robot software (eg. obstacle avoidance, mapping, and direct physical interfaces).  Meanwhile, you provide the brains in the form of a tablet (eg. iPad or Android).  In theory, this should open up mobile robot application development to a much broader audience, creating the oft-discussed robot app store.  When combined with the recent announcement of the Scooba 230 floor cleaning robot (which I will certainly purchase), I would say iRobot is still innovating!

Robot Coffee Machines: The Tassimo BrewBot Commercial

Coffee Machine Robot: Tassimo BrewBot by Bosch

Many folks visiting Hizook today are looking for a "robot coffee machines," specifically, the Tassimo BrewBot by Bosch.  In actuality, BrewBot is not a robot at all!  They are using a cute robot coffee machine to sell decidedly non-robot coffee makers, and it makes me sad... I want the actual robot! Either way, kudos to the clever marketers at Bosch for making such a great commercial (embedded below).  In the meantime, if you're interested in seeing a real coffee making and delivering robot, go check out the Nestlé Nespresso Nesbot.  Dang it, now I've got a hankering for an espresso...

Electropermanent Magnets: Programmable Magnets with Zero Static Power Consumption Enable Smallest Modular Robots Yet

Electropermanent Magnets Enable Programmable Matter Robots (Robot Pebbles)

Take a moment and envision an electromagnet: a simple coiled wire driven by a hefty electrical current gives a fully-programmable magnetic field strength (on, off, and everything between).  Electromagnets are ubiquitous, but it turns out that there is a little-known device with similar functionality yet zero static power consumption -- they are called electropermanent magnets, and they've been around and in use since the 1960's!  A 2010 PhD thesis by MIT Media Lab's Ara Knaian examines the physics, scaling, trade-offs, and several new actuator designs (eg. stepper motors) using these little-known wonders.  Recently, electropermanent magnets facilitated an innovation in "programmable matter," where they were instrumental in creating the world's smallest self-contained modular robots to date (12mm/side).  Read on for details about this fascinating technology, along with discussions about existing and possible robotic applications.

Heartland Robotics To Build Low-Cost ($5,000) Mobile Manipulators?

Heartland Robotics

Heartland Robotics, the stealthy robotics startup founded by iRobot co-founder and robotics legend Rod Brooks, was in the news again last week after closing a $20M financing round.  Little is known about the company beyond broad superlatives from executives about building robots to "increase productivity and revitalize manufacturing."  Now, successful fundraising by a robotics startup is great news, but alone it was insufficient to draw my laser-focus away from thesis work.  However, a article this weekend provided a tantalizing new nugget of information that I absolutely must share -- Heartland is working on a new mobile manipulator with a $5,000 projected price point complete with one or two arms, grippers, sensor head, and a mobile base.  If coupled with a depth camera (eg. Kinect) and a decent computer, this could be a really compelling robot platform!  If this price point is real, perhaps those superlatives aren't so inflated after all...  

Spiralift: The Ultimate Telescoping Linear Actuator

Spiralift telescoping linear actuator

After many years of searching for the perfect telescoping linear actuator, I would like to share my discovery of the I-Lock Spiralift 75 (ILS75) prototype by Paco Spiralift.  The ILS75 has a compact form factor (10x15x15 cm) that can telescope out to 1.6 meters while lifting a 175kg load (350+ lbs).  It relies on a system of interlocking horizontal and vertical metal bands that "unroll" to lift a load, a process best illustrated in the videos embedded below.  The ILS75 is just one Spiralift offering; others range all the way up to a goliath version (Spiralift ND18) that can lift an 11,000 kg load 12 meters (25,000 lbs to 40 ft).  To date, Spiralift mechanisms have been applied to theater stage-lift systems and automotive lifts.  At Hizook, we believe robotics is a compelling application, especially as a robot's vertical spine (eg. on EL-E, Cody, and PR2) -- increasing the robot's effective workspace to include floor and tables, and also for compact and easy transportation.  As such, we're working with Paco Spiralift to gauge roboticsts' interest and vet the technical specs of the ILS75 -- tell us what you think in the comments.

Georgia Tech's Cody Robot Makes Progress Towards Autonomous Bed Baths for Patient Hygiene

Cody Robot Gives Bed Baths

A few weeks ago, my labmates from Georgia Tech's Healthcare Robotics Lab presented a paper at IROS 2010 entitled, "Towards an Assistive Robot that Autonomously Performs Bed Baths for Patient Hygiene."  Their work used Cody, a robot with compliant arms, and a specialized "bath mitt" end effector to perform wiping motions that could clean selected areas of an actual person's body, including the upper arm, forearm, thigh, and leg.  In this robotic cleaning task, the robot initiated and actively made contact with a human.  The psychological impact of such robot-initiated contact is an interesting question -- one I believe will be important for future healthcare and human-robot interaction (HRI) tasks.  Read on for a video and discussion by the authors.

KUKA Combines "World's Strongest Robot Arm" with Omnidirectional Base

KUKA Titan Robot Arm on OmniMove (holonomic) Mobile Base

KUKA has developed an impressive array of omnidirectional robot platforms: OmniMove, OmniRob, and youBot. A new video on the youBot Store shows how an OmniMove holonomic base (containing eight mecanum wheels) can be transformed into a seriously heavy-lifting mobile manipulator through the addition of a huge Titan robot arm, which has been called the "world's strongest robot arm" and is capable of lifting 1000 kg.  The video (embedded below) shows this latest platform towering over the smaller youBot platform. I wonder if this new platform would qualify for BattleBots...?  It would make for a fun exposition match!

Electroadhesive Robot Grippers from SRI International

Electroadhesive Robot Gripper

Apparently novel robot end-effectors are popular this week (see the particle jamming robot grippers), as we've spotted another: a previously-unseen robot gripper from SRI International that uses an electrically controlled reversible adhesion called electroadhesion.  We've looked at SRI's electroadhesive wall-climbing robots before, where electrostatic forces are able to support extreme loads with relatively little power consumption. Several friends and I ruminated about the possibility of embedding the electrodes in a robot's gripper to ease manipulation, but it seems SRI beat us to the punch.  It also looks like they're developing general-purpose, highly-compliant electroadhesive pads for a variety of applications; according to the specifications, I should be able to walk up a wood wall using a pad of less than 16x16 inches2 while consuming less than 18 milli-Watts -- cool stuff!  Few details are currently available, so I will post updates in the comments as we learn more.  In the meantime... pictures! 

"Jamming" Robot Gripper Gets Official: Article Published in PNAS

Jamming Robot Gripper

Remember that compliant "jamming" end effector unveiled by Colin Angle (iRobot CEO) at TEDMED 2009?  Even then, it was demonstrated picking up medication bottles, keys, and water bottles (a hand-held version was also demonstrated).  Well, it just got a whole-lot more official with the publication of "Universal robotic gripper based on the jamming of granular material" in the Proceedings of the National Academy of Sciences (PNAS).  The cool thing about this method of grasping is its relative simplicity: a rubber sack (balloon) filled with coffee grounds is pressed onto an object, it conforms to the object's natural contours, and the air is pumped out (a volume change less than 0.5%) to form a stable grasp-- no complex grasp planning required.  Be sure to check out the new video and photos!

Robots Make and Deliver Pancakes: A Cooperative Effort By a PR2 (TUM's James) and TUM-Rosie

PR2 and Rosie Combine Efforts to Make and Deliver Pancakes

Dejan Pangercic of the Intelligent Autonomous Systems Group at TUM (Technische Universität München) wrote in to show us a cool dual-robot demonstration where a PR2 robot (TUM's James) and TUM-Rosie combine their efforts to prepare and deliver pancakes -- Yum!  The demonstration system is quite impressive, featuring: door and drawer opening, object recognition, grasping and manipulation, navigation, multi-robot cooperation, etc.  The demo seems to use a fair bit of stock ROS functionality, as well as some new functionality and CRAM integration (Cognitive Robot Abstract Machine, a reasoning framework from TUM).  I'm anxious to learn more about the system: assumptions, limitations, and methods.  Hopefully more advanced details are forthcoming.  Check out the video below.

PR2 Robot Autonomously Delivers Medication Using UHF RFID -- Live on CNN

PR2 Robot LIVE on CNN

Yesterday Georgia Tech's PR2 robot made a LIVE appearance on CNN.  The event was accompanied by interviews of Dr. Charlie Kemp (director of Georgia Tech's Healthcare Robotics Lab and my advisor) and Keenan Wyrobek (Willow Garage figurehead).  Travis Deyle (yours truly) was also present and responsible for the robot demonstration.  While some of the PR2's movements (some driving, waving to the audience, etc) were scripted or teleoperated via joystick, the actual medication delivery demonstration was fully autonomous and used UHF RFID sensing (a major component of my PhD research), the base laser rangefinder, and a slightly-modified TrajectoryPlannerROS.  The demo went off without a hitch, and as Keenan mentioned on the PR2-Users mailing list, "Their demo is a milestone (albeit a gutsy one) for PR2.  The first nationally televised, LIVE, sensor-based demo with a PR2."  Check out the video (embedded below), as well as some behind-the-scenes pictures of the PR2 inside CNN's studio.

Willow Garage's Texai Telepresence Robot Makes a Cameo Appearance on Big Bang Theory

Texai telepresence robot on Big Bang Theory

Tonight's episode of Big Bang Theory, a comedy sitcom about CalTech scientists / engineers, prominently featured a telepresence robot as "Shel-Bot."  Specifically, the show featured Willow Garage's telepresence robot called Texai that was covered in the NY Times just a few weeks ago.  Apparently this is the second robot appearance in Big Bang Theory's new season (one in each of two new episodes) -- though I have yet to watch last week's episode with a "gratifying" robot manipulator. It's so nice to see real robots on TV, though I'm sure my wife could live without my excited banter and shutter clicks as I (literally) take screenshots with our DSLR camera (see shots below).

Tandy Trower Launches Hoaloha Robotics: A Seattle-Based Robotics Startup

Hoaloha Robotics Robot Concept

There is an interesting article in the Seattle Times about former Microsoft robotics evangelist, Tandy Trower, launching a new startup named Hoaloha Robotics.  His goal is to create a $5k-10k personal robot (aka mobile manipulator) in the next five-to-ten years that can address the needs of older adults, such as telepresence activities and other healthcare tasks.  Hoping to leverage cheap 3D sensing (like depth cameras a la Microsoft's Kinect) and inexpensive computing, this one-man (so far) company is another entrant in a new, budding market.  Having been personally involved with the design, construction, programming, and brief home-deployment of a mobile manipulator (EL-E), I can confidently say that Tandy & co. have a lot of work cut out for themselves -- I wish them luck and success.

Telepresence Robots in the News

Robotic exoskeleton from the 1950s

I would like to point out two news items involving telepresence robots that are definitely worth reading.  First, a "manifesto" reprinted from the June 1980 issue of Omni magazine where artificial intelligence pioneer, Marvin Minsky, shares his views on telepresence (a term he originally coined).  His essay includes a prediction of remote avatars (ie. Surrogates), operation in hazardous / remote environments, and even a discussion of how little development has occurred since the 1950's (remember, his essay is from 1980; did you know that full-body exoskeletons were produced back in the 1950s?!).  Second, a NYTimes article by John Markoff that discusses five top American contenders in the space: Vgo (Vgo Communications), Tilr (RoboDynamics), Texai (Willow Garage), RP-7i (InTouch Health), and QB (Anybots).  The article captures the society aspect and high-level overview but lacks meaty technology details (though the side-by-side photo montage is useful for direct comparison).

Aldebaran Robotics Announces Nao Educational Partnership Program

Nao Robot from Aldebaran Robotics

By now, you're probably familiar with the Nao humanoid robot from Aldebaran Robotics -- the robot that supplanted the Sony Aibo as the robot du jour for Robocup's Standard Platform League (international robot soccer competition) back in 2007 and retains that prestigious title yet.  Recently, Aldebaran announced a new Educational Partnership Program that aims to expose students of higher education to the joys of programming advanced robots.  Contemporaneously, Aldebaran announced a set of four product derivatives to match varied academic budgets, ranging from full humanoids, to upper-body manipulation rigs, and 2-DoF robot heads for audio-visual experimentation (see details below).  Crucially, this new initiative provides a stable hardware platform with a comprehensive software suite (alternatively, extensive open-source ROS drivers) to match your educational, research, or just whimsical robot needs.

DARPA Autonomous Robot Manipulation (ARM) Robot


Apparently my hunch about the recent humanoid being the standard platform for the DARPA Autonomous Robot Manipulation Software (ARM-S) program was spot-on!  A new blog post on confirms that this is the DARPA "ARM Robot" and that there is a public contest to name the robot.  The blog post gives a few hardware details: "The 'ARM Robot' has two Barrett WAM arms, BarrettHands, 6-axis force torque sensors at the wrist, and pan-tilt head. For sensors, it has a color camera, SwissRanger depth camera, stereo camera, and microphone."  The program winners are also enumerated: Carnegie Mellon University, HRL Laboratories, iRobot, NASA-Jet Propulsion Laboratory, SRI International and University of Southern California.  Be sure to check out the video of the (now confirmed) unnamed DARPA ARM-S robot platform embedded below. Updated Sept. 1st, 2010: This robot was integrated / developed by RE2, a Carnegie Mellon spin-off located in Pittsburgh, PA that specializes in agile defense robotics with an emphasis on intelligent mobile manipulation platforms.

SRI Seeking Qualified Job / Intern Applicants to Work on Cool New Humanoid Sporting Dual Barrett WAM Arms

REsquared Humanoid Robot

Dr. Motilal Agrawal from the Artificial Intelligence Center at SRI International just sent an email to the robotics worldwide mailing list seeking qualified PhD or Masters job candidates (or interns) with experience in ROS, C++ / Python, and grasping / manipulation.   In the email, Dr. Agrawal points to a movie that shows off a new humanoid robot  being used at SRI that sports dual Barrett WAM arms, each with a Barrett three-fingered hand -- see the movie embedded below.  I can't wait to see what SRI plans to do with its new robot; they always seem to do such thorough work.  You'll notice that this design is becoming increasingly common, from Intel / CMU's HERB robot to Alexander Stoytchev's robot at Iowa StateUpdated Aug. 31st, 2010:  My hunch was correct; we just received confirmation that this robot is indeed the "standard" hardware platform for the DARPA ARM-S program and was developed / integrated by RE2.

Snake Robots Can Now Climb Trees

Snake Robot Climbs Tree

I just stumbled across an amazing new video (embedded below) from Howie Choset's Biorobotics Laboratory at CMU of a teleoperated snake robot climbing a tree.  While I have seen a lot of snake robots built over the years, including some amphibious versions that can swim, this is the first time I have seen one climbing a tree -- a task that some biological species do amazingly well!  This is clearly a case of personal ignorance; other snake robots from the Biorobotics lab have been performing similar feats for years, as evidenced by videos from 2008 (also embedded below).  However, I was sufficiently captivated by the new and old videos to share them with you.
