Mechanical arm

We chose to make a mechanical arm because we think it's easy but fun to make. The purpose of this mechanical arm is to grab small objects like golf balls, chocolate bars etc. The materials we're using are syringes,  tubes, plywood, cardboard, wooden sticks, Popsicle sticks, small bowl, and hot glue. One problem I think we'll face is to make the mechanical arm sturdy.
