This paper presents an attitude control strategy in the three planar space robots having two DOF for docking operation of a free flying hexagonal object using the bond graph technique for modeling and simulation. As the highly non linearity, strongly coupled and non-holonomic characteristics of a free flying space robot, the position and posture of the base body changes when the free floating s...

This paper presents a methodology to analyze dynamics of flexible space robot using bond graph. In case of space robots the position and orientation of the satellite main body may change when the manipulator moves. Motion of the space robots also induces vibrating motions in structurally flexible manipulators. Researchers working on terrestrial flexible robot arms principally have focused on is...

in this paper, we consider the problem of efficient computation of the forward kinematics of a 6 DOF robot manipulator built to use in rehabilitation purpose. Forward kinematics problem (FKP) of parallel robots is very difficult to solve in comparison to the serial manipulators. This problem is almost impossible to solve analytically. Numerical methods are one of the common solutions for this p...

This paper presents a modeling method for a mobile modular manipulator (MMM) interacting with the environment, which is composed of a mobile base and a 5-DOF manipulator. A tactile sensor, which is installed at the tip of the end-e ector of the mobile manipulator, is to detect the feedback information from the environment. The dynamic equations are formulated and the controller is proposed with...

Obtaining the joint variables that result in a desired position of the robot end-effector called as inverse kinematics is one of the most important problems in robot kinematics and control. As the complexity of robot increases, obtaining the inverse kinematics solution requires the solution of non linear equations having transcendental functions are difficult and computationally expensive. In t...
