Prosthetic Arm From Foam Board

This instructables describes how i made a prosthetic arm from foam board.In these days i was learning about 3-d printed prosthetic arms, and i decided to make a prototype of prosthetic arm .After a bit of brainstorming , I chosen foam board,because it is the best material to build any prototypes.

Lets get started.......

1. foam board
2. fevikwik- Instant adhesive
3. cotton swabs
4. rubber bands
5. thread
6. screw

By using a hobby knife i cut foam board as per the design.

I used instant adhesive to combine different foam board pieces.

In every joints i inserted cotton swab tubes to get partial revolution.

To make holes on foam board i used heated steel pin.

I inserted rubber band to get elastic action to the fingers.

I tied threads to the tip of finger and by pulling it we can move the finger.
