Sensor Accessories

The sensor subsystem gives the robot the ability to detect various things in its environment. The sensors are the “eyes and ears” of the robot, and can even enable the robot to function independently of human control. A robot senses its environment and adjusts its own behaviors based on that knowledge.

Integrated Encoder Modules
Integrated Encoder Modules are designed to provide you with direct and detailed information from your robot's motors. Simply replace the plastic cap on your motor and install the encoder. You can then be told which direction your motor is moving, how fast, and its distance traveled.
