METHOD OF ROBOTIC SYSTEM DYNAMIC VELOCITY MODIFICATION
20230123463 · 2023-04-20 ·

A method and system for robotic motion planning which perform dynamic velocity attenuation to avoid robot collision with static or dynamic objects. The technique maintains the planned robot tool path even when speed reduction is necessary, by providing feedback of a computed slowdown ratio to a tracking controller so that the path computation is always synchronized with current robot speed. The technique uses both robot-obstacle distance and relative velocity to determine when to apply velocity attenuation, and computes a joint speed limit vector based on a robot-obstacle distance, a maximum obstacle speed, and a computed stopping time as a function of the joint speed. Two different control structure implementations are disclosed, both of which provide feedback of the slowdown ratio to the motion planner as needed for faithful path following. A method of establishing velocity attenuation priority in multi-robot systems is also provided.

A robotic system includes a robotic vehicle having a propulsion system, one or more sensors that image data representative of an external environment, and a controller that determines a waypoint for the robotic vehicle to move toward. The controller determines limitations on movement of the robotic vehicle toward a waypoint. The limitations are based on the image data. The controller controls the propulsion system to move the robotic vehicle to the waypoint subject to the limitations on the movement to avoid colliding with one or more objects. The controller determines one or more additional waypoints subsequent to the robotic vehicle reaching the waypoint, determines one or more additional limitations on the movement of the robotic vehicle toward each of the respective additional waypoints, and control the propulsion system of the robotic vehicle to sequentially move the robotic vehicle to the one or more additional waypoints.

Method and system to generate a 3D model for a robot scene

A robot is configured to perform a task on an object using a method for generating a 3D model sufficient to determine a collision free path and identify the object in an industrial scene. The method includes determining a predefined collision free path and scanning an industrial scene around the robot. Stored images of the industrial scene are retrieved from a memory and analyzed to construct a new 3D model. After an object is detected in the new 3D model, the robot can further scan the image in the industrial scene while moving along a collision free path until the object is identified at a predefined certainty level. The robot can then perform a robot task on the object.
