Goal: Design and build a mechanical "robotic" hand model with moving fingers

Materials

• plastic glove
• String
• Rubber bands
• Pipe cleaners
• Kleenex
• Tissue paper

Constraints

• 1 plastic glove
• 2 feet of string
• 5 rubber bands
• 5 pipe cleaners
• 15 kleenex or 2 tissue papers

Constraints - continued

• The hand must have moveable fingers and thumb. Each finger should move independently and all together. It does not have to grasp, but it can!

Concepts to consider...

• How does the human hand work?
• How does a mechanical hand work?
• Would the fingers move independently?
• Would the fingers bend? (ligaments, tendons, muscles)

So I'm not here to answer questions but you know the drill. I suggest you work in groups of 2 - 3, go find some ideas, look at your hand...
