Sub-Micro Servo 3.7g (Generic) This generic sub-micro servo is one of the lightest servos we carry, weighing just 3.7 g (0.13 oz) without the lead. It is intended for use between 4.8 and 6 V (i.e. with 4- or 5-cell NiMH or NiCD battery packs). Servo horns and associated hardware are included.
Stepper motors may also be used for controlling position but these will consume power even in the rest period for just locking and holding the commanded position. So, servo motors are typically used in industrial robotics as a high performance substitute to the stepper motors.
