Detailed Description

Class for IR sensors.

IR sensors are based on distance measurements using the ODE geom class Ray. The sensor value is obtained by collisions, which are handled by the simulation environement. The information of a collision comes to the sensor via the collision callback of the substance used for the ray (actually for the transform). However of no collision is detected the sensor needs to ajust its output as well. Therefore a reset function is provided.
