Abstract

The invention provides a PSD-based robot arm leveling and locating system comprising a high-precision automatic leveling line laser, a high-precision PSD module and a circuit module. A laser ray serves as the datum line of the PSD-based robot arm leveling and locating system provided by the invention, then the PSD-based robot arm leveling and locating system is matched with three PSD units to be used, PSDs can read the position coordinates of light spots formed by crossing of the ray and the PSDs through the circuit module, the accurate deflection direction and angle of a robot arm can be judged according to the coordinate values on the three PSDs, and 10-m precision can be smaller than 0.1 mm. A signal communication circuit is arranged and adopts RS485 communication, the speed can reach 100 hz or above, the signal transmission speed is increased greatly, thus the leveling and locating speed of the PSD-based robot arm leveling and locating system is further promoted, modulation light is adopted for a light source from the high-precision automatic leveling line laser, interference of external background light is avoided effectively, and then overall precision of the PSD-based robotarm leveling and locating system is improved.

Description

technical field [0001] The invention relates to the field of robots, in particular to a PSD-based robot arm leveling and positioning system. Background technique [0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. Robots have basic characteristics such as perception, decision-making, and execution. They can assist or even replace humans in completing dangerous, heavy, and complicated tasks, improve work efficiency and quality, and serve human life. Expand or extend the scope of human activities and abilities. [0003] With the continuous development of science and technology, people's research on robots is becoming more and more mature. In the existing technology, the flatness of the robot arm is mainly based on vision technology or angle sensors. There are still some deficiencies in the system, for example, its positioning speed is relatively slow, and it is also easily interfered by external background light, resulting in inac...
