PMKS Simulations
The following three videos display animations for the three linkage components of my mechanism in the range they were used.
Video 1. PMKS simulation of the motion of the arm component used in the prototype (about 75 degrees to -75 degrees).
Video 2. PMKS simulation of the motion of the top gripper component of the claw.
Video 3. PMKS simulation of the motion of the bottom gripper component of the claw.
