Tabarah, E. December 1, December ; 4 : — Two algorithms are developed in this paper for the optimal motion coordination of a pair of industrial robots engaged in contact operations such as part machining or deburring. In the first algorithm the two robots jointly grasp a tool, and move it in such a way that it performs a prescribed contact operation along the surface of a workpiece.
If researchers want to reproduce the results they can extract this input data from these plots using suitable software tools. Robotic stabilization of a therapeutic radiation beam with respect to a dynamically moving tumor target can be accomplished either by moving the radiation source, the patient, or both. As the treatment beam is on during this process, the primary goal is to minimize exposure of normal tissue to radiation as much as possible when moving the target back to the desired position. Due to the complex mechanical structure of 6 degree-of-freedom 6DoF robots, it is not intuitive as to what 6 dimensional 6D correction trajectory is optimal in achieving such a goal. With proportional-integrative-derivative PID and other controls, the potential exists that the controller may generate a trajectory that is highly curved, slow, or suboptimal in that it leads to unnecessary exposure of healthy tissue to radiation. Motion planning was formulated as an optimization problem and solved at real-time speeds using the L-BFGS algorithm. Three planning methods were investigated, moving the platform as fast as possible platform-D , moving the target along a straight-line target-S , and moving the target based on the fastest descent of position error target-D.
Motion planning , also path planning also known as the navigation problem or the piano mover's problem is a computational problem to find a sequence of valid configurations that moves the object from the source to destination. The term is used in computational geometry , computer animation , robotics and computer games. For example, consider navigating a mobile robot inside a building to a distant waypoint. It should execute this task while avoiding walls and not falling down stairs. A motion planning algorithm would take a description of these tasks as input, and produce the speed and turning commands sent to the robot's wheels. Motion planning algorithms might address robots with a larger number of joints e. Motion planning has several robotics applications, such as autonomy , automation , and robot design in CAD software , as well as applications in other fields, such as animating digital characters , video game , architectural design , robotic surgery , and the study of biological molecules.
