Robot Rover Sentinel

Sentinel Rover

Sentinel is a rover robot type like that NASA has sent to Mars. It is our mascot and is always on display in our lobby.

Inspired by the project: “Google Lunar X Prize” the first version of Sentinel was build by hand, with saws, metal file and a drill press between 2009 and 2010. Later, we bought a CNC, Metal Brake, Metal Lathe and many more tools to create professional robots. If you look at the making-of gallery below, you can see the evolution! Sentinel was the first inspiration of InnoTechnix.
