My guess:

A contraption for the ramp.

What a great idea! Using a cam for lifting against the ground is a unique way of levitating robots.

Brilliant idea! That's a pretty smart way to get some lift.

Reminds me of 16's cams in 2004.

Re: pic: 245 Teaser

thats brilliant! but i've got some questions for you;

what kinda motor is driving that?
how long does it take to lift?
is it lifting 4" or 12"?
and are you lifting one or two robots?

thanks

Great mechanism! Just toss two of those onto your 2005 bot and you might have similar results to 2005. (or at least one can hope so)

Wow, I have been talking to my VEX team about using a cam design for grasping the bar. This will be a really great visual aid to show them. Great Idea guys.

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?

Re: pic: 245 Teaser

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

06-02-2007 20:37

MattLi

Re: pic: 245 Teaser

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).

Re: pic: 245 Teaser

what happens when the power goes off?

07-02-2007 20:03

MattLi

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).
