Khepera mobile robot
From Wikipedia, the free encyclopedia
The Khepera is a small (5.5 cm) differential wheeled mobile robot that was developed at the LAMI laboratory of Prof. Jean-Daniel Nicoud at EPFL (Lausanne, Switzerland) in the mid '90s. It was developed by Edo. Franzi, Francesco Mondada, André Guignard and others.
Small, fast, and architectured around a Motorola 68331, it served researchers for 10 years, widely used by over 500 universities[1][citation needed] worldwide. It is now outdated, even with its upgraded processor and flash in version 2.0.

[edit] Scientific impact
The Khepera was sold to a thousand research labs and featured on the cover of the August 31th, 2000 issue of Nature [2]. It appeared again in a 2003 article [1].
A Google scholar search with khepera mobile robots returns 2350 hits [2]. The Khepera helped in the emergence of evolutionary robotics [3][4].
