Abstract
There are several common approaches used to obtain the kinematic and dynamic equations which describe the motion of robot manipulators. However, a problem arises when these conventional body oriented robot arm kinematic equations are used to simulate the manipulator motion. In this Case, the jocobian matrix which relates the end effector" motion to joint angle variations becomes singular when two successive arm links align. When the robot arm passes through these singular points, the jacobian matrix is not invertible, and a result of this, the motion cannot be simulated. This thesis investigates how this situation can be avoided by using a Newton Euler approach to variable difinition, and using the equations interpretted in a fixed reference frame.
