The telescoping arm never made it onto a bot but its purpose was to reach the top of the clown to place five rings.
The scissor lift was intended to place the rings on top of the clown. The lift ended up being to unstable and would lean to far to one side.
The rotating arm was intended to get a full pull in any direction that the ring was in. The pull came to be to slow and the ring would slide out of the hook.
