Joseph’s Robotic Hand

Hello again, this is Joseph, the 10 year old teacher at Tech 101 Kids. I am going to show you how to make an easy homemade robotic hand using straws and strings.

What You’ll Need

These are the supplies needed to make the straw hand

• five straws

• string

• sharpie

• scotch tape

Steps

1) Tape four straws together with scotch tape.

2) The fifth straw is taped on the opposite side of where the thumb is.

3) With the Sharpie mark each of lines in your hand.

4) Cut a diamond on the lines by bending it forward.

5) Do it for all of fingers.

6) When its all done, take one string and pass it from one end to the other of the straw. Do it in each straw.

7) Make a small cut on the top of the straw. Make a knot on the string, secure it in the cut with a piece of tape.

8) Do it with all and you get this.

9) Then if you pull the strings, the hand will close its fingers..

10) You can even lift it paper balls with your new robotic hand and it won’t fall (possibly).

Well, I hope you enjoyed doing this robotic hand to impress your friends. Visit more of my posts to learn more cool projects to do.
