Alex, it seems like if you have the ramps drop off of the front and back of the robot, and all cams are facing the same direction, then driving in one direction would rotate all cams and lift both platforms.

That looks like Andy Mark Treads, tracked wheels perhaps?

So how much pulling force do you need to get the lift done?

Not much, My guess is about 10-20 lbs of pulling/robot I'm guessing. I could pull it with just my arms (I'm not a very strong person).

what happens when the power goes off?

Re: pic: 245 Teaser
 
Unless the robot suddenly moves/jerks when the power is shut off then we won't have any problem (yes that's right there's no electricity involved).
