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 It is now outdated, even with its upgraded processor and flash in version 2.0.
