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.......
Step 1: Materials Used:
- foam board
- fevikwik- Instant adhesive
- cotton swabs
- rubber bands
Step 2: Design:
Step 3: Cutting
By using a hobby knife i cut foam board as per the design.
Step 4: Finger Tip Design:
I used instant adhesive to combine different foam board pieces.
Step 5: Connecting Fingertip With Proximal Phalanx
In every joints i inserted cotton swab tubes to get partial revolution.
Step 6: Construction of Palm:
Step 7: Assembling Parts:
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.
