Abstract

The invention provides a robot control, track connection and smoothing method and system. The robot control, track connection and smoothing method comprises the steps that a task instruction is issued through an interactive interface; receiving a task instruction, and performing motion planning on the robot in combination with the current state of the robot; if the planning fails, the planning path is not generated; if the planning succeeds, a planning path is sent to a track connection and smoothing processing module, and a smooth track meeting a real-time process sampling period is automatically generated and issued to a servo system; executing the smooth track, and controlling each joint of the robot to move according to the smooth track. The real-time track smooth processing module is used for synchronizing the motion track in the real-time process and the motion track in the non-real-time process; and the non-real-time track smooth processing module converts the non-real-time track into a real-time track and then synchronizes the real-time process and the non-real-time process about the motion track. The adaptability and intelligence of the robot are improved, and the strong dependence of the robot on the environment is reduced.

Description

Technical field [0001] The present invention relates to the field of robotics, in particular, to a robot control, track interface with smoothing method and system. Background technique [0002] Robot is a high precision, MIMO, highly nonlinear and strong coupling of the system, because it has the property of automation, such that the robot in the field of industrial manufacturing, medical treatment, semiconductor manufacturing and space exploration play important features . Traditional real-time control of the robot control system, the control cycle is very short, and therefore high accuracy can be realized at the same time also have a stable performance function, while the task is simple, a conventional robot control architecture can well meet the needs of a single repeated application scenario , such as the loading and unloading facility, the robot is only necessary to repeat a fixed path. But with the popularity of robotic applications, their faces also become more complex sce...
