We were going to attach wheels onto the bottom of the platform but we thought it would be more difficult when we demonstrate with them on. The object we were going to was a box with a handle but we decided to use a swing that we made instead because with thought it would be easier to lift. First we tried using two big syringe and a small one but we thought that the big one would have too much weight on the arm, so instead we changed it to using two small syringes and one big one.
