Directions:

1. Fold the finger joints at the lines.
2. Cut standard drinking straws to size (leave a little gap between the lines to help thread the yarn).
3. Tape straw pieces to the hand.
4. Thread yarn through the straw pieces. Each finger will have a length of yarn of its own.

How do you make a homemade robotic hand?

Procedure

1. Trace a hand onto cardboard and cut it out.
2. Cut straws into 1-inch pieces (or 1/2 inch if you have a small hand!).
3. Using the tape, attach the straw pieces to the hand (see top image).
4. Crease the cardboard in between the straws – these will simulate your joints (see red lines on top image).

Do robot hands exist?

Robotic arms and other robotic instruments may sound like a futuristic development, but they have been around for years, helping out surgeons and engineers alike. Less common, though, are prosthetic, robotic arms that allow people who have lost a limb to regain freedom of movement.

How do you make cardboard fingers?

Tape them lengthwise, one per section of the cardboard. Thread a string through all the the straw segments. Tape it down at one end, and leave a loose end hanging out the other end. Pull on the loose string to bend the “finger joints.” Optional – add a handle to make it easier to hold on and pull the string.
