Sensors are components that indicate the position or velocity of bodies as output signals.
Sensors have to be connected with bodies, just like joints.
The position of the sensor is indicated by its connection point. The connection point is shown automatically when you make a connection between a body and a sensor. First change to Connection mode (), then click the body and then click the sensor.
The Create Connection dialog will pop to ask you for the location of the connection point. In the connection dialog you can set the offset (both the position as well as rotation) from the body reference frame to the connection point.
Various sensor types are available in the library.
