André Guignard
André Guignard is a robotics engineer whose small machines help researchers study movement, interaction, and cooperation. After training as a watchmaker, he moved into electrical engineering and joined EPFL in 1976. He designed a mouse encoder for EPFL, helped turn the Dépraz mouse into Logitech’s first mouse, redesigned Khepera, and built Robota’s mechanics and s-bots that could grip each other. His later work included mechanics for AmphiBot and Salamandra robotica and a 2026 neural-control study of fishlike swimming. As of October 2026, he is a technical specialist at EPFL’s Processor Architecture Laboratory and a scientific adviser to two EPFL groups.
Timeline
-
1976
Joining EPFL's computer lab
After training as a watchmaker, he moves into electrical engineering and joins EPFL in 1976.
-
1977
A mouse encoder
In 1977, he designs a reliable optical-encoder mechanism to measure mouse-ball movement.
-
1980–1983
Industrializing the Dépraz mouse
From 1980 to 1983, the hemispherical mouse he designs is manufactured by Dépraz and sold by Logitech as its first mouse.
-
1993
Redesigning Khepera
In 1993, he, Francesco Mondada and Edo Franzi redesign a five-centimetre student robot as Khepera.
-
1999–2005
Building Robota's mechanics
In 1999, Aude Billard needs a Robota doll with moving legs and a head; he builds its mechanics and adds moving eyes in 2005.
-
2001–2005
Building the s-bots
During the European SWARM-BOTS project of 2001–2005, he builds 35 s-bots that grip one another to pass obstacles.
-
2005
AmphiBot and salamander robots
He develops the mechanics for AmphiBot and Salamandra robotica. In 2005, he coauthors a paper on swimming and crawling with an amphibious snake robot.
-
As of October 2026
Neural control at EPFL
In 2026, he coauthors a Science Robotics study in which ZBot uses a model inspired by neural circuits to reproduce larval zebrafish swimming gaits. As of October 2026, he is a technical specialist at EPFL’s Processor Architecture Laboratory and a scientific adviser to two EPFL groups.
