In the previous chapter, you built a compact forklift and programmed it to move boxes from one place to another. Did you notice that the forklift was unable to carry unevenly shaped objects or even circular objects properly from one place to another? Well, forklifts can easily lift square and rectangular boxes, but to pick up small objects, circular objects, or anything else that's an obscure shape, we need to implement a grabber with a hand-like grip that can easily grab and drop things.

Your wrist, palm, and fingers act as a load-carrying agent, your elbow is the fulcrum, and they work together. You will be implementing the same concept while building this grabber and replicating the movement of your hand. The following figure shows a robot with a grabbing arm like the one we will...
