In this chapter, we've been using the program rbtjnts.f to solve a problem involving the robotic arm problem. With the information in the link diagram, plus the values of the angles of the robotic elbow joint, it is possible to determine the X-Y positions of the robotic wrist and wrist joints.
The kinematic for locating the wrist and wrist joints can also be determined. These are left as an exercise. Assume that the elbow joint angles are measured in degrees clockwise from the arm link to the forearm link.
You are asked to modify the rbtjnts.f program as follows:
Compile, run, and test the new program.
