How to make the robot
Select a hard cardboard box, draw the template on it and cut the pieces out carefully. Cover the pieces smoothly with duct tape until the cardboard is not strong enough. Attach the pieces together and fix the syringes to get a perfectly working hydraulic robot. On pressing the syringes, pressure is created that helps in the robot to move.
