Abstract
A robotic system includes a robot for moving a payload in response to a calculated input force. Sensors in respective sensor housings are connected to a handle, each sensor including a light emitter and receiver. The sensors measure a light beam received by a respective receiver. A controller calculates the calculated input force using received light. Each sensor housing modifies an interruption of the light beam in a sensor when the actual input force is applied, and the controller controls the robot using the calculated input force. A method of controlling the robot includes emitting the light beam, flexing a portion of the sensor housing(s) using the actual input force to interrupt the light beam, and using a host machine to calculate the calculated input force as a function of the portion of the light beam received by the light receiver. The robot is controlled using the calculated input force.
