Description

technical field [0001] The present invention relates to the technical field of robots, in particular to a method and system for updating a robot posture. Background technique [0002] A robot is a machine that realizes various functions by its own power and control ability. It is a machine that can be changed by a computer or programmed to perform different tasks. Robots can bring a lot of convenience to humans. Robots It usually consists of an actuator, a drive device, a detection device, a control system and a complex mechanical structure. Among them, the detection device is used to detect the robot's action and current working conditions in real time, and feed back to the control system in real time as needed. The control system communicates with After the preset information is compared, a corresponding execution command is issued to adjust the actuator to ensure that the action of the robot meets the predetermined requirements. [0003] Sensors used as detection devices...

Problems solved by technology

One is the external information sensor, which is used to obtain information about the robot's work object and the external environment, so that the robot's actions can adapt to changes in the external situation, so that it can achieve a higher level of automation, and even make the robot have a certain "Sensation" is developing toward intelligence. For example, external sensors such as vision and sound provide information about the working object and the working environment, and use this information to form a large feedback loop, which will greatly improve the working accuracy of the robot. The robot passes the detection The device perceives its current posture in real time, and updates its own state in real time according to the subsequent feedback signal. In the prior art, the algorithm for the robot to perceive its own state is too complicated, which makes the calculation load of the processor too large and the calculation time is too long. Poor real-time performance
