Keyboard Actuator

A ‘fake’ actuator that allows to move a robot from the keyboard.

This actuator does not require a connection with external data. It simply responds to the keyboard arrows to generate movement instructions for the robot attached.

When parented to a robot, the user can press the arrow keys to modify the linear and angular velocities (V, W) of the robot.
