Design and build a Hydraulic Claw that works just like the games in an arcade! Move the upper cylinder and watch your claw open and close below. We have documents to get you started, but the final claw design up to you! Can you design a claw to pick up specific objects (worms, marshmallows, balls)? Take a look at the photos above for ideas and inspiration.
