TRAJECTORY PATH PLANNING AND MANAGEMENT OF ROBOT ARM MOVEMENTS
The present invention relates to a trajectory generating method for moving a Robot Arm in the fastest and smoothest path by avoiding obstructions and jerky movements in the shortest possible time to predetermined endpoints, by implementing a planning, sequence and trajectory path manager to plan the movements ahead of time and concurrently creating a database of trajectory paths that is subsequently used for storing and retrieving of repetitive movements of the Robot arm, resulting in time saving and smooth movements. In a dynamically changing operating environment, endpoints are calculated through the implementation of an intelligence module that captures a three-dimensional image of the processing area and predicts a 3D pose, which in turn is translated to positional coordinates for the Robot to utilise, to move to the target endpoint. The planning manager working in sync with the intelligence module and sequence manager enables a very favourable environment to seamlessly and efficiently move objects smoothly at controlled speeds, mimicking human movement.
A simple interchange mechanism is provided for a robot arm to reliably, quickly and consistently change over from one end effector to another for the purpose of executing multiple tasks without the need to install different robots. The interchange mechanism incorporates mechanical and electromagnetic elements at three different areas that work synchronously, resulting in a flexible and scalable architecture that is simple yet stable, and adaptable to different configurations of the robot.
