Khepera mobile robot

Résumé
The Khepera is a small (5.5 cm) differential wheeled mobile robot that was developed at the LAMI laboratory of Professor Jean-Daniel Nicoud at EPFL (Lausanne, Switzerland) in the mid 1990s. It was developed by Edo. Franzi, Francesco Mondada, André Guignard and others. Small, fast, and architectured around a Motorola 68331, it has served researchers for 10 years, widely used by over 500 universities worldwide. The Khepera was sold to a thousand research labs and featured on the cover of the 31 August 2000 issue of Nature. It appeared again in a 2003 article. The Khepera helped in the emergence of evolutionary robotics.
