How do you make a robotic hand science project?

Step 4: Creating Your Robotic Hand

  1. Fold the fingers at the lines.
  2. Cut smaller straws to size (leave a little gap between the lines to facilitate in threading the yarn).
  3. Tape straw pieces to the hand.
  4. Thread yarn through the straw pieces.
  5. Thread all five pieces of yarn through the bigger straw.

How do you make a prosthetic hand with straws?


  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).

What do you need to make a prosthetic hand?


  1. Plastic drinking straws.
  2. Needle (Use caution and adult help when handling sharp objects.)
  3. String.
  4. Paper clips.
  5. Modeling clay.
  6. Assorted small objects to pick up.
  7. Scissors.
  8. Tweezers (optional)

What do you need to make a prosthetic arm?

Fabrication of a prosthetic arm or prosthetic hand relies on two plastic manufacturing methods: injection molding and vacuum forming. Prosthetic limbs are made from plastic polymers, which bond fabric-based layers together to make a prosthesis that is strong yet lightweight.

How can a kid make a robot?

A bristlebot is a simple and tiny robot your kids can build at home using a toothbrush. Cut off the bristle end of the toothbrush and connect a small pre-isolated motor with some coin cell batteries. This little setup is quite easy to make, but the experience of building it is rewarding and fun for kids.

How does a prosthetic arm work?

An electrically powered prosthesis uses motors and batteries to transfer the desired movement and power to the prosthesis. Depending on your level of limb loss, the electrical components will vary. Sensors and varied inputs function by detecting motion in the muscles in your residual limb or upper body.
