Detailed steps to fabricate the hand are below, but can also be found on the Popular Science website.
Materials
- 1x6-inch board or other support material
- 1/4-inch O.D. vinyl hose
- Tape
Tools
- Hot glue gun and glue sticks
- Drill and drill bits
Assembly
- Use hot glue to firmly attach each finger to the end of the 1x6-inch board or other support (the prototype used a plastic toy gauntlet) to form a hand. (see picture)
- Attach a length of 1/4-inch O.D. vinyl hose to the open hose barb on each finger.
- Secure the hoses to the board or other support using tape, or drill holes to allow the PVC tubing to be routed.
- Now the hand is complete, but it still needs a control system. Follow the instructions for the Control Board Fabrication.
