One does not simply pick 217. :cool:

Take a look at our Breakaway robot, Weeble. Rather simple mechanism, grappling hook and winch.

That was my initial idea, but you would not reach past the first level because of the notches on the side which stick out about an inch.

Specifically, the knuckle sticks out quite far on the front, and the gusset extends in the back of the pole, too.

I dont think I read anythign pertaining to this but before a climb could a bot disconnect its drive system and essentially leave it behind to reduce weight and size? Obviously the rio, battery, and control would climb but the drive train abandoned? The whole thing woudl be designed as a quick disconnect.

No
The robot cannot intentionally leave parts behind. G13

So if your robot can get 30 points from the hang, they are a keeper for a great partner to frisbee shooting robots.
I like the idea of a "Loch Ness Monster challenge" being thrown down each year.

I see that they posted pics of their bot here: http://www.chiefdelphi.com/media/photos/35361
But the only pic that is broken is the one for the latching.
1717 Used a gas spring to lift themselves up. This was an excellent idea because even if they grabbed the tower at the last second, the robot would still go up the tower even after the robot was disabled. That mechanism wouldn't work this year as it reacted against the top surface of the tunnel.

Ok, our team was thinking of an extending hook that would grab the 3rd rung and winch us up as we drove up the side of the pyramid and stopped at possibly the 20 point zone. Would this be against the rule that says we would need to climb up sequentially?

Yes. If you grab the 3rd rung while on the floor, you are not climbing sequentially (because the floor is Level 0).

We used magnets on our minibot for logomotion and have discussed this...

Electromagnets may violate R32.

Please review <G22>. Also consider what the robot will do once it leaves the ground - can the bot acsend past a bar in that orientation?
