Optimal Trajectory Planning of a Mobile Robot with Spatial Manipulator For Spatial Obstacle Avoidance
Mobile robots that consist of a mobile platform with one or many manipulators mounted on it are of great interest in a number of applications. Combination of platform and manipulator causes robot operates in extended work space. The analysis of these systems includes kinematics redundancy that makes more complicated problem. However, it gives more feasibility to robotic systems because of the e...
متن کاملTrajectory Planning and Control for Mobile Manipulator Systems
Mobile manipulator systems, comprised of a mobile platform with one or more manipulators, are of great interest in a number of applications. This paper presents a methodology for computing actuator commands for such systems that allow them to follow desired end-effector and platform trajectories without violating the nonholonomic constraints. Based on a reduction of the system dynamics, a model...
متن کاملSub-Optimal Trajectory Planning of Mobile Manipulator
In this paper, a trajectory planning method of a mobile manipulator is presented. We derive the dynamics of the mobile manipulator considering it as the combined system of the manipulator and the mobile platform. The planning problem is formulated as an optimal control problem. To solve the problem, we use the concept of the order of priority. A gradient-based iterative algorithm which synthesi...
متن کاملOptimal Trajectory Planning of a Box Transporter Mobile Robot
This paper aims to discuss the requirements of safe and smooth trajectory planning of transporter mobile robots to perform non-prehensile object manipulation task. In non-prehensile approach, the robot and the object must keep their grasp-less contact during manipulation task. To this end, dynamic grasp concept is employed for a box manipulation task and corresponding conditions are obtained an...
متن کاملJerk Bounded Trajectory Planning For Non-Holonomic Mobile Manipulator
Mobile manipulator systems comprising of a mobile platform with one or more manipulators are of great interest in a number of applications. This paper presents a modeling of the system without violating the nonholonomic constraints of the platform. Trajectory planning by soft motion and seventh order polynomial to control jerk acceleration, and velocity, is also presented. The hub torque requir...
