In this paper, a mobile robot named VicRoB with 6 degrees of freedom (DOFs) driven by three tracked vehicles is designed and analyzed. The robot employs a 3-PPSR parallel configuration. The scheme of the mechanism and the inverse kinematic solution are given. A path planning method of a single tracked vehicle and a coordinated motion planning of three tracked vehicles are proposed. The mechanical structure and the electrical architecture of VicRoB prototype are illustrated. VicRoB can achieve the point-to-point motion mode and the continuous motion mode with employing the motion planning method. The orientation precision of VicRoB is measured in a series of motion experiments, which verifies the feasibility of the motion planning method. This work provides a kinematic basis for the orientation closed loop control of VicRoB whether it works on flat or rough road.

This paper developed a 6-DOF (degree of freedom) PC-Based robotic arm system. The system mainly include in software platform and servo control card, servo control card based on microcontroller STC12C5A60S2 was designed to drive the servomotor connected with each joint of robot. The software was implemented by combining MFC with OpenGL. By using the OpenGL functions, the software is able to draw and simulate the 3D kinematic scheme of the robot, it also provides 3D motion planning simulation feature. With the help of simulation in the GUI, users can visualize the manipulator motion planning. Furthermore, user also can control the real robotic arm through this software. Finally, point-to-point motion and continuous path motion are all tested in simulation and real robot control. The entire system has been successfully implemented.

This paper presents an integrated motion planning and control framework for a nonholonomic wheeled mobile manipulator (WMM) system taking advantage of the (differential) flatness property. We first develop the kinematic model of the system and analyze its flatness properties. Subsequently, a statically feedback linearizable system description is developed by appropriately choosing the flat outputs. Motion-planning can now be achieved by polynomial curve fitting to satisfying the terminal conditions in the flat output space while control design reduces to a pole-placement problem for a linear system. A case study of point-to-point motion is considered to study the effectiveness of pose stabilization in the WMM. The simulation and experimental results highlight the ease-of-implementation of proposed method for online real-time integrated motion-planning/control within a hardware-in-the-loop (HIL) electro-mechanical testing.
