Stepper Motor Actuators

Motor control is one of the most important issues in robotics. In general, mobile robots require motors to control two kinds of section: one is related to robot locomotion and the other is related to the movement of the end effectors placed on the robot itself.

The movement of the end effectors can be managed by using a two-phase bipolar stepper motor. This synchronous electric motor divides a full rotation into a large number of steps. The motor's position can be controlled precisely, without any feedback mechanism. In this way, robotic developers can concentrate their efforts on writing only the most advanced algorithms able to perform inverse and forward kinematics.
