This nameless robot has been dubbed "Smoovy", as it was based on the (now discontinued?) smoovy motors. This robot comes from the Microprocessor Systems Lab at Ecole Polytechnique Federale De Lausanne, or EPFL -- a University in Switzerland -- where numerous micro robots (such as Jemmy, Inchy, and Alice) were developed. The builders of this robot actually went on to found Didel, a provider of micro-robot components (such as the motors for Pico, another micro robot). Unfortunately, this robot lacks (detailed) technical specifications, but it is very aesthetically pleasing and has a phenomenal mechanical design with custom-machined gears. Smoovy measures in at 1 cm3 and appears to be tethered.
Here is what Smoovy's homepage says about the robot:
This robot has been built by André Guignard and programmed by Olivier Matthey.
It uses two smoovy 3mm motors from RMB. A first gear transmits the movement to the wheels, made of the second gear level. The initial design was using a rubber caterpillar, but its efficiency was too weak. The robot does not fit any more into one cubic centimeter. We have to find better ideas for the next generation.
A PIC 16C54 drives directly the motors. Two photo-transistors and one LED have been bonded on the side in order to follow a wall. This is not yet operating well; the ambient light is too strong compared to the LED power.
