stairs
 
Has anyone thought about how to climb onto the 6 inch platform yet. We have a few ideas, but I need some help brainstorming.

Just think about different wheel systems and don't forget about proper ground clearance.

Re: stairs
 
would front tank treads on an angle work? How would you get around bottoming out?

I fyou had tank treads running the length of the bot, you should have no problem bottoming out.

I'm waiting to see the ideas that some of the more innovative teams come up with at regionals and nationals. This year's Xerox Creativity awards will all be well earned, I'm sure.

check out 225's robot from 3 years ago- they had a really cool wheel system.. hard to explain but basically they had 8 wheels, 2 on each side with an extra wheel attached like 0=0. they could rotate this addition so that it looked like they were tiptoeing.. that system would allow you to pick up your robot's rear as the front goes over the stair..


good luck finding a solution- i'd like to have a 1218/341 brainstorming session if possible, you guys are awesome

Re: stairs
 
absolutely, let me know when you would want to and I will get my team together. We just came up with a pretty interesting idea. Trying to work it out on cad now.

Come on, I want to see some brainstorming! I say we just get these bots to fly. That would make this comp so much better.

We used this in 2001 to go over the 4x4 under the bar. It worked very well, we somehow got 4th place at VCU.

Treads are good but out riggers with help. go and find 1999 videos. You will see how fast a robot can climb. The good robots did not even slow down going over the puck. It was done all in a nice fuild motion.

I'm not going to release details, but my hint is that following:

Think about how your body shifts when climbing stairs, and why.

There's pictures and videos of that here:

It shows how cumbersome and ineffective it is. Although it is a solution, there are better ways.
