Suppose the wrist joint of the robots arm is allowed to
Chapter 8, Problem 72(choose chapter or problem)
Suppose the wrist joint of the robots arm is allowed to rotate at the joint connection S and the arm is located as shown in the first figure. The upper arm has a length of 15 inches; the forearm, without the hand, has a length of 10 inches; and the hand has a length of 7 inches. Approximate the coordinates of R by using Exercise 72(a) (b) Suppose the robots upper arm is rotated 75, and then the forearm is rotated 80, and finally the hand is rotated an additional 40, as shown in the second figure. Approximate the new coordinates of R by using
