Jemmy is a micro robot 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 Smoovy, 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). Jemmy measures in at 1 cm3 and appears to be tethered.
From Jemmy's homepage:
- Driven by two synchronous 3 mmØ RMB smoovy motors.
- Four passive infrared sensors.
- Embedded PIC microcontroller, which generates the 3-phase signals for both motors, performs time-to-voltage conversion to read the sensors, and communicates using a single-wire bidirectional link with an optional supervision unit. To speed up software development, all variables of the embedded processor can be read/written through this communication channel.
- Precision gearing, 8 miniature ball bearings
- This robot was the winner of the International Microrobot Maze Contest '97, Nagoya (Japan) in the 1 cm3 category.
