Prototypes are a way to practice building something to see how it works.  A prototype helps engineers to test things that work, or do not work, and find ways to improve something.

Your job is to build a prototype robotic hand, and then find ways to improve it!

Once you have built your prototype robotic hand, find ways to make it better.  Can you use other materials to make it strong?  Can you change it to make it do new things?  Be creative!
