Robotics & Motors
Robotics is the scientific and engineering discipline concerned with the creation, composition, structure, evaluation, and properties of embodied artificial capabilities. It does not include naturally occurring capabilities or artificial intelligence without a physical presence
A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any position sensor for feedback (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed. Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
