This sensor emulates the remaining charge of a battery on the robot. It is meant to be used only as an informative measure, to be taken in consideration by the planning algorithms. It does not prevent the robot from working.
The charge of the battery decreases with time, using a predefined Discharge rate specified as a property of the Blender object. This rate is independent of the actions performed by the robot, and only dependant on the time elapsed since the beginning of the simulation.
A planned feature is to allow for designated Charging Zones where the battery will gradually recharge. However, this is not implemented yet.
The Empty object corresponding to this sensor has the following parameters in the Logic Editor panel:
