1. An apparatus comprising:
- a first motor and a second motor in a body of the apparatus;
a planetary gear system in the body of the apparatus, the planetary gear system including a sun gear, a ring gear, and planetary gears, wherein the first motor is coupled to the sun gear to drive movement of the sun gear in the planetary gear system to control rotation, and the second motor is coupled to the ring gear to drive movement of the ring gear in the planetary gear system to control vibration, and wherein the sun gear and the ring gear drive the planetary gears, and the planetary gears combine the rotation from the first motor and the vibration from the second motor; and
a carrier coupled to the planetary gear system to move a moving portion of the apparatus, the moving portion coupled to a head, the head designed to be in contact with a user when the apparatus is in use.
