We highly recommend that teams purchase 3 IR Photoreflectors and 2
IR Distance Sensors per kit. The autonomous portion of the game will
be much easier if the robots have proper sensors. The sensors
listed below will require some modification to fit into the plugs on
the robot controller. We will be happy to help you with these
issues.
The IR Photoreflectors will tell a robot how light or dark the color
of an object is, and three are used to help the robots follow a line
painted on the field.
