Khepera mobile robot

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 has served researchers for 10 years, widely used by over 500 universities worldwide.

Scientific impact

The Khepera was sold to a thousand research labs and featured on the cover of the 31 August 2000 issue of Nature.[1] It appeared again in a 2003 article .

A Google scholar search with khepera mobile robots returns 4800 hits . The Khepera helped in the emergence of evolutionary robotics .

gollark: I see. Sounds like a convoluted way to do it.
gollark: I bet you'll tell me it doesn't use a global ERRSTRING variable for error handling next.
gollark: Really? Hmm.
gollark: How do they interact with the Macron borrowed GC malloc checker?
gollark: Where is the spec for them?
