Status: new base used successfully for Eurobot 2011.

All our robots are built around a drive base. This base can be reused every years and is composed of:

• a pair of motors with their large wheels to make the robot move,
• smaller wheels mounted on optical coders to sense the robot movement.

The robot uses a differential drive. This means that there is right and left motors and both must be running at the same speed to follow a straight line.

The coder wheel are independents of the driving wheel. This enables the robot to detect loss of adherence of the driving wheels.
