Motors become generators when forced to turn while no or reduced power is applied. This phenomenon brings interesting benefits in terms of energy efficiency but it also introduces challenges in system design. Understanding the physics and implications of regeneration is critical in many applications.

Using a simple tension sensor - such as a spring and potentiometer - Roboteq controllers can be used to create electromechanical systems that produce constant pulling or pushing force. These techniques depart from traditional motion control and enable a whole array of innovative force amplification and stabilization applications.

Drive-by-wire or teleoperated systems feel very unnatural to use because they lack the natural feedback the operator receives when turning a steering, presuring an object in his or her hands, or pressing on a pedal. This lack of feedback is uncomfortable in many situations, to outright dangerous in others. Yet force feedback is reasonably simple to implement.
