  • Publication number: 20240025038
    Abstract: A robot control method, a legged robot using the same, and a computer-readable storage medium are provided. The method includes: obtaining a motion parameter of a driving mechanism of a target part of the robot; and obtaining an end pose of the target part by processing the motion parameter of the driving mechanism according to a preset forward kinematics solving model, where the forward kinematics solving model is a neural network model trained by a preset training sample set constructed according to a preset inverse kinematics function relationship. In this manner, a complex forward kinematics solving process can be transformed into a relatively simple inverse kinematics solving process and neural network model processing process, which reduces the computational complexity, shortens the computational time, thereby meeting the demand for real-time control of the robot.

  • Patent number: 11759945
    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.

  • Publication number: 20230046296
    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.
