An electronic speed controller includes an output circuit and one or more processors. The output circuit is configured to control currents to a plurality of motors of an unmanned aerial vehicle (UAV). The motors are configured to drive the UAV. The one or more processors are configured to, individually or collectively, determine an operating state of a first motor of the plurality of motors, collect power from the first motor in response to the operating state of the first motor is a decelerating state, and distribute at least a portion of the power collected from the first motor to a second motor of the plurality of motors.

Method and system for recycling motor power of a movable object

Systems, methods, and devices for assigning addresses to a plurality of functional modules carried by a movable object are provided. In one aspect, a method can comprise: (a) transmitting an activation signal from a control module to a functional module of the plurality of functional modules via a first communication interface, thereby activating the functional module for addressing, wherein the plurality of functional modules are each configured to control a component of the movable object; (b) transmitting an addressing signal comprising an address from the control module to each functional module of the plurality of functional modules via a second communication interface different from the first communication interface, thereby causing the address to be assigned to the activated functional module of step (a); and (c) repeating steps (a) and (b) for each functional module, thereby assigning an address to each functional module.

Addressing method for functional modules of a movable object

A method of redistributing motor power of an unmanned aerial vehicle (UAV) includes determining, with aid of one or more processors, an operating state of a motor of the UAV. The motor is configured to drive a corresponding rotor to generate lift for the UAV. The method further includes determining, with aid of the one or more processors, how to redistribute power from the motor between a plurality of components when the motor has an operating state that is a decelerating state, and redistributing the power in accordance with the determination of how to redistribute the power.

A method for recycling motor power includes controlling a first motor of an unmanned aerial vehicle (UAV) in a decelerating state to work in concert with a second motor of the UAV in an accelerating state to effect rotation of the UAV, receiving power from the first motor at a power bus in electrical connection with the first motor and the second motor, and providing a portion of the received power to the second motor through the power bus during the rotation of the UAV.

A method of recycling motor power of a movable object is provided to recycle and redistribute power from at least one motor in a decelerating state. The method comprises determining whether an operating state of at least one motor of the movable object is a decelerating state, and recycling power from the at least one motor having a decelerating state. The method also comprises redistributing the recycled power to other power consuming components of the movable object. The method of present invention increases the energy efficiency and a battery life of the movable object. The movable object may be an unmanned aerial vehicle (UAV).
