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.

Inside the robots
We use Phidgets controllers to drive the Rover.
2x 12v batteries 7.5AMP that we recharge by connecting a power cord directly to the rover. One battery used for the motors and the second for the electronics.
The Rover is remotely controlled via Wi-Fi of Ethernet (for local testing).
