Our design is pretty simple, where we have two arms (sort of like ladders) that will have lead screws running through them, with two cims running on a shaft that will turn a chain (connecting to gears) that will turn the nut/lead screw.

Then with a cable and pulley system (which is kinda hard to explain without showing you our set up -- that is currently disassembled) the arms will extend at twice the rate we put into it. Basically, it is similar to a princton forklift that Lowe's uses.

So, by using a total of 6 Cims, and 2 window motors (which will be used for our second set of hooks that will keep our bot steady on the pole), we are wondering if we will be able to get enough torque and speed out of the Cims (which we can always gear properly later), will we use up too much battery juice on defending/pushing other bots and then still want to pull a 140lb robot up to the third tier.

If you still have further questions about our design, let us know.
