Robot Rover Sentinel

Sentinel Rover

Sentinel is fully working Robot Rover inspired by the one NASA has sent to Mars. This Rover is loaded with electronics and has hundreds of parts. It is our mascot and is always on display in our lobby.

This item is a prototype and is not for sale.

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 ITNX.
