Document Type and Number:
WIPO Patent Application WO/2019/206198
Kind Code:
An autonomous apparatus, moving and performing a preset operation within a defined area of operation. The autonomous apparatus comprises an energy module for providing energy thereto, a motor, a sensor circuit, and a control circuit. The motor acquires energy from the energy module and drives the autonomous apparatus to move and/or to operate within the area of operation. The sensor circuit measures operational parameters and environmental parameters of the autonomous apparatus and transmits measurement results to the control circuit. The control circuit controls the operation of the motor according to the signal transmitted by the sensor circuit. The motor is sensorless and brushless. Before the motor begins rotation, the control circuit measures a resistance value of the motor, and estimates, on the basis of the resistance value of the motor, rotor position, so as to control the operation of the motor.
