Following the steps of the engineering design process and acting as robotics engineer, student teams will use drinking straws to design and build a robotic hand. This robotic hand will mimic the way human fingers work: tendons bend the fingers while the muscles in the forearm control the action.

To understand the physiology of the human hand and learn how human fingers work.
To apply the engineering design process to design a working hand.
To design and build a working hand out of craft materials that demonstrates how a real robot hand might work.
