Abstract: An active three-dimensional positioning device and a control system for floor-cleaning robot are provided in the present invention. The active three dimension positioning device includes a radio frequency (RF) receiver array, a radio frequency emitter and a control circuit. The RF receiver array includes a plurality of RF receivers for receiving a RF pulse. The RF emitter is used for emitting a RF pulse. The control circuit is coupled to the RF receivers. The control circuit transmits a transmission command to the RF emitter, after the RF emitter receives the enable RF signal, and the RF emitter emits the RF pulse. The control circuit calculates the position between the RF receiver array and the RF emitter according to the positions of the RF receivers and the time when each of the RF receivers receives the RF pulse.

Abstract: A self-balance mobile carrier is provided in the present invention. The self-balance mobile carrier includes a first direction load cell, a second direction load cell, a third direction load cell, a fourth direction load cell, a motion apparatus and a control circuit.
