Dynamics computation of structure-varying kinematic chains and its application to human figures
This paper discusses the dynamics computation of structure-varying kinematic chains which imply mechanical link systems whose structure may change from open kinematic chain to closed one and vice versa. The proposed algorithm can handle and compute the dynamics and motions of any rigid link systems in a seamless manner without switching among algorithms. The computation is developed on the foun...
متن کاملMotion planning and bimanual coordination in humanoid robots
Humanoid robots have a large number of “extra” joints, organized in a humanlike fashion with several kinematic chains. In this chapter we describe a method of motion planning that is based on an artificial potential field approach (Passive Motion Paradigm) combined with terminal-attractor dynamics. No matrix inversion is necessary and the computational mechanism does not crash near kinematic si...
متن کاملDynamics computation of closed kinematic chains for motion synthesis of human figures
This paper discusses the dynamics computation of closed kinematic chains, especially those found in motions of human gures. A number of e cient dynamics computation algorithms have been established in robotics for open kinematic chains and particular types of closed kinematic chains, such as parallel ve-bar link mechanisms and the Stewart platform. The dynamics computation of closed kinematic c...
متن کاملA Low Friction Demanding Approach in Gait Planning for Humanoid Robots During 3D Manoeuvres
This paper proposes a gait planning approach to reduce the required friction for a biped robot walking on various surfaces. To this end, a humanoid robot with 18 DOF is considered to develop a dynamics model for studying various 3D manoeuvres. Then, feasible trajectories are developed to alleviate the fluctuations on the upper body to resemble human-like walking. In order to generate feasible w...
متن کاملVisual Self-Calibration of Pan-Tilt Kinematic Structures
With the increasing miniaturization of robotic devices, some actuators are not provided with absolute position sensing, thus making the state of the system unknown at startup. In this paper we present a vision based method for the automatic calibration of serial pan-tilt kinematic structures with a perspective camera on the end-effector. Examples of such systems are surveillance cameras and hum...
