Mechanism evolution [35 pts] This robotic gripper mechanism, which is symmetric about the x-axis, will be used to take rock samples from Mars, but you need to figure out how the gripper mechanism opens and closes as the piston is extended and shortened. The lower gripper arm is pinned to the piston AB and link CD. In this problem you will analyze just the bottom half of the gripper as piston AB extends by 25 mm (to 225 mm).
