For this robot design, I wanted to highlight frustration and unpredictability with a common action taken by people, grabbing an object. The video highlights how the robot is uncontrollable and is unable to grab the ball. From the audience perspective, it would have been assumed the robot could have grabbed the ball, but it is shown that the ball can escape the limited mobility of the robot.

The current design uses two hinges that can rotate around the same axis, while two additional hinges were used to emulate a solid that can clasp an object. I was unable to figure out how to rotate the two hinges to grab the ball. I think I would need to extend out the solids and rotate across a the orthogonal axis or use an alternative system.
