Hydraulic robot made of cardboard and scotch duct tape.

Step 2: Draw the template

Now draw the template on the cardboard, these are the measures that I used but you can change them to make a smaller or bigger robot.
From the template cut out:
2 x A piece
2 X B piece
2 x C piece
2 x D piece
1 x E piece
These are the main parts of the body and the rest of the parts are going to be made as you go because they depend on the thickness of your cardboard and how many layers of duct tape you use. Because I used thick pizza box I only needed one layer.

its really cool but i think it would be really helpful if u put the template original size co that we can print it out especially for the claw it is really confusing.

On your C part have you left out a Measurement wear it gose down
to 1/2" should this be 1 1/2" ?

i corrected it because in the robot with 1 1/2" when you put the cube that holds the claw, the 1 1/2" is to tall and does not let the claw open. if you make it 1/2 its exactly the same height of the cube that holds the claw so the claw can open all the way.

look at step 8:
-Picture 3 the sides are higher that the claw holder, claw cant open
-Picture 4 sides are modified to be flush with the claw holder, claw can open freely
