Embodiment Construction

[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0010] Please refer to FIG. 1 , a robotic arm positioning system 100 provided by an embodiment of the present invention includes a robotic arm 10 , a cube-shaped support 20 and a signal processing system (not shown).

[0011] The mechanical arm 10 is a mechanical arm that can move within a predetermined space. The mechanical arm 10 includes two arm parts 101, a rotating shaft part 102 and a clamping part 103, the two arm parts 101 are connected by a rotating shaft part 102, each arm part 101 can rotate around the corresponding rotating shaft part 102 .

[0012] The clamping part 103 is used to realize the grasping action of the robot arm. In this embodiment, the gripping part 103 is configured as a jaw, and its two jaws can be opened and closed to realize the gripping action of the robot arm. The clamping part 103 can be set in different styles according t...

Abstract

The present invention provides a manipulator-positioning system, which comprises a manipulator, a cubical fixed mount and a signal-processing system; wherein, the manipulator can move within the range of a predefined space; the cubical fixed mount is mounted outside the predefined space. The manipulator comprises two arm parts and a rotary shaft part connecting the two arm parts together; wherein, the manipulator can rotate along the rotary shaft part; the rotary shaft part is provided with two camera modules, which can take a photo every certain time interval. Each three edges at any two diagonal positions on the cubical fixed mount are respectively provided with a row of illuminating indicators, which can periodically twinkle. The signal-processing system is used to process photos taken by the camera modules. The manipulator-positioning system can effectively acquire the absolute position of a clamped part and avoid accumulative errors.

Description

technical field [0001] The invention relates to a mechanical arm, in particular to a positioning system for the mechanical arm. Background technique [0002] Automation is an effective way to improve industrial productivity and product quality. The robotic arm plays an extremely important role in industrial production automation. Robotic arms have been widely used in automatic assembly, assembly and extraction of objects or some dangerous, difficult and unsuitable tasks for human beings. In the automatic control of the robotic arm, it is necessary to accurately control the motion trajectory of the robotic arm. Therefore, the development of precise control technology has become extremely important in the motion control of the robotic arm. [0003] A general robotic arm uses information such as an encoder on the rotating shaft and the length of the relevant robotic arm to determine the position of the gripping part of the robotic arm, or to calculate the position of the robo...
