Sensors

A crucial aspect of any robotics project is the ability for the robot to report back information about its environment or to automatically react and adjust if certain conditions are met. For example, a contact, optical or sonic solution could be employed to detect nearby objects to restrict movement of the robot to protect itself or the objects around it.
