Estimation and Control of a Robot Using Photodiodes

T. Pound, P.R. Bélanger, A. Helmy Two stationary photodiodes receive light from a LED mounted on a robot. Since the 2D projections are mathematically related to the task space position of the LED, the signals can be used in a Kalman filter to estimate the position and velocity of the LED. These estimates serve as inputs to a task-space control algorithm.
