Alternative Solution 3

Alternative solution Three
The third and final alternative solution is the vertical closing arm. This arm is also turned by a screw as seen in the above illustration. The screw will be turned by a motor which will be attached at the back end of the arm. As the motor turns the screw, the screw will then turn a gear which will move the top vertical arm either up or down depending on the turn of the screw. This arm will be able to grasp medium to large objects, rather than small or intricate objects.
