A robotic arm obstacle avoidance path planning method, device and storage device

Abstract

The invention provides a mechanical arm obstacle avoidance path planning method and device and a storage device. The mechanical arm obstacle avoidance path planning method is characterized in that animproved A * algorithm is adopted, the obstacle avoidance path of the tail end of a mechanical arm from a starting node to a target node is searched, so that the problem that the mechanical arm collides with an obstacle is solved, smoothing treatment is carried out on the obstacle avoidance path according to a cubic uniform B-spline curve method, so that the problem that due to the fact that the mechanical arm shakes, the control error is large is solved. The mechanical arm obstacle avoidance path planning device and the storage device are used for achieving the mechanical arm obstacle avoidance path planning method. The mechanical arm obstacle avoidance path planning method and device and the storage device have the beneficial effects that through the provided technical scheme, the mechanical arm is prevented from colliding with the obstacle in the working process, the control error of the mechanical arm is reduced, the path tracking precision of the mechanical arm is improved, the mechanical vibration generated in the movement process of the mechanical arm is reduced, and the service life of the mechanical arm is prolonged.

Problems solved by technology

At present, most of the research on obstacle avoidance path planning of manipulators does not consider the problem of real-time obstacle avoidance path planning and the situation of dynamic obstacles in the environment, resulting in related methods that cannot be generally applied to more complex scenarios.
