Abstract: A dual-output-shaft servo includes a housing including two first sensors and two actuating mechanisms. Each actuating mechanism includes a motor assembly, a speed reduction mechanism opposite the motor assembly, and a transmission mechanism arranged between the motor assembly and the speed reduction mechanism. The speed reduction mechanism includes an output component, and a connection shaft is fixed to the output component. A first sensor counterpart is attached to an end of the connection shaft which faces the motor assembly. The transmission mechanism is to transmit mechanical power from the motor assembly to the speed reduction mechanism. The axes of rotation of the output components of the speed reduction mechanisms are skew or intersected with each other.

Abstract: A robot joint configuration determining method, a robot using the same, and a computer readable storage medium are provided. The method includes: simulating a joint model of a first joint of the robot using first motion deviation data to obtain first result data; simulating the joint model using second motion deviation data to obtain second result data; taking the motion deviation data corresponding to one of the first result data and the second result data meeting one or more preset conditions as a target motion deviation data for the first joint; and determining type information of a reducer in a configuration information of the first joint based on the target motion deviation data. In the present disclosure, the motion deviation of the first joint that is relatively accurate can be obtained through the results of the two simulations.

Abstract: A bidirectional energy storage device for a joint includes: a sleeve comprising an open end and an opposite, closed end; an elastic member attached to the sleeve; a sliding member slidably arranged at the open end of the sleeve, wherein opposite ends of the elastic member are respectively in contact with the closed end of the sleeve and the sliding member; a first telescopic link comprising a first end pivotally connected to the sliding member and an opposite, second end; and a second telescopic link comprising a first end pivotally connected to the sliding member and a second end. The second ends of the first telescopic link and the second telescopic link are pivotally connected to a rotating member at an end of the joint, and the first telescopic link and the second telescopic link are to extend and retract to drive the sliding member to side along the sleeve.
