| Abstract: | Free-obstacle motion planning of a tomato harvesting manipulator was studied based on a pseudo-distance approach. An optimization technique and alternative approach using a forward kinematics was applied to solve the path planning,which was modeled with consideration of manipulability measure maximization and obstacle avoidance for links of the manipulator. The simulation results show that the tomato harvesting manipulator can avoid obstacles successfully and reach the objective position along a specified g... |
