Seven degrees of freedom robot

Abstract

The invention relates to a seven-degree-of-freedom robot, and belongs to the technical field of robots. The seven-degree-of-freedom robot comprises a mechanical arm and a probe, wherein a main body structure of the mechanical arm comprises a base, a waist column, a large arm, a small arm, a first wrist part, a second wrist part, a third wrist part and a fourth wrist part, which are connected in sequence through joints; and the joints can be rotated around corresponding rotating planes H. The seven-degree-of-freedom robot can be used for maintenance of such machinery as a rail vehicle steeringframe in a narrow range.

Description

technical field [0001] The present application relates to a seven-degree-of-freedom robot, which belongs to the technical field of robots. Background technique [0002] The rail vehicle bogie is the key system for the safe operation of the train and the focus of vehicle inspection. In order to improve work efficiency, it is a trend in the future to use robots to automatically collect images instead of manual automatic detection. Although industrial robots have been widely used in the fields of automobile and automobile manufacturing, machining industry and electronic and electrical industry. In industrial production, industrial robots such as welding robots, assembly robots, painting robots and handling robots have been widely used. However, most industrial robots are bulky, complex in structure, less flexible enough in degrees of freedom, and lack automatic obstacle avoidance functions. Facing bogie systems with complex structures and narrow spaces, such robots cannot alw...

Problems solved by technology

However, most industrial robots are large in size, complex in structure, less flexible enough in degrees of freedom, and lack automatic obstacle avoidance functions. Faced with bogie systems with complex structures and narrow spaces, such robots cannot always meet the requirements for use.

[0003] At present, the working path of most industrial robots needs to be planned in advance. A few robots have an alarm function beyond the limit range, but they cannot achieve automatic obstacle avoidance. Even a small number of service robots are designed with ultrasonic or laser ranging sensor technology. However, limited by the structural form and technical principles, it cannot meet the requirements of the bogie inspection to meet the working conditions of collecting images in narrow spaces and complex structures.
