Rotation Sensors

These are built into the NXT motor. The MindStorm kits can have a rotation sensor added to them (that sensor is also not as accurate as the NXT sensor), but it's not a part of the motor.

Objects need to be tall enough to be "seen" when close to the sensor.

The robot will move forward for 2 full rotations of its wheels. It will then stop for one second and then turn around.
