AbstractIn this paper, a forward kinematics problem is concerned with the relationship between the individual joint of robot arm and the position and orientation of the tool or end-effector. The standard Denavit_Hartenberg(D-H) analytical scheme is applied to building mathematical modeling to predict, simulate and recovering the end-effector location (position and orientation) placement of 5DOF R5150 Robot manipulator for different joint variables, the basic challenge associated with the R5150 arm is the limited information available on its governing control model for position placement. Two ways by which control can be effected on R5150 arm, this robot can be programmed by using either a hand-held terminal (teach pendant) or a RoboCIM simulation software. The non-versatility of this control software is seen in the non-availability of a programmable environment by users. The user interface of RoboCIM allows for numeric keyboard inputs such that each input results in the orientation of a specific joint by a margin equivalent to the input. The relationship between the keyboard inputs and joint motion of the arm is not feasible to the users. The proposed D-H scheme as presented herein has successfully reproduced the end-effecter position of the Lab_volt R5150 Robot arm with marginal differences for different experimental trials. The simulation of robot arm forward kinematics is performed through MATLAB. The adopted modeling is validated in the physical behaviors in determine position of robot arm.
