Hydraulic Arm
We received first place in a competition where we used the flow of air, to make an arm move up and down, side to side, and be able to pick up a ball so that way it could drop into a desired location
The Hydraulic arm was made out of cardboard, syringes, nails, and zip ties. With syringes connected to various peaces of the arm, each syringe controlled a specific feature. One syringe made the claw open and close to grab the ball. Another syringe made the claw go up and down to get out of the way of an obstacle. The last syringe made the arm turn side to side. With this design, me and two other members were able to break the speed record of grabbing a ball from a location, dodging an obstacle, placing the ball down, and then doing the same backwards. It only took 19 seconds.
