Construction of hydraulic arm

Our construction of our arm is going very well.There was only one change so far ,it was instead of using those 2 long sticks we compromised with Popsicle sticks.so far we got 3 wooden planks and attached them together for the base. We also attached 8 pairs of Popsicle sticks together with pins. Then inside of those Popsicle sticks we got glued little Popsicle sticks to create a surface for the string to push on. The last thing we did so far is we created the top part of the claw with will pick up the ball.
