Let's Make Robots!

The Climber - Third ride - It works!!!!!

Climb stairs

Hi guys !

I'm working on a robot from plywood. He should the stairs up and down ride.

He receives four strong (12kg/cm) servos modiefied for continuos rotation and one Sharp IR and probably two bumper switches.

My first Climber was finished, but he had two problems:

- first and last stair, so I had to change the design.

I hope that now everything is good.

very very innovative design!!!!! awsm work dude 

tooo many resistors tooo :P

Unusual but who cares. Necessity is the mother of invention. Do you see steering with some sensors in the future. It would be great to bring me a beer downstairs.

Thanks, i was in holiday so i couldt se about it did work ;)

Why do you have blue paper and tape on the upper stair?

Is it for another project you are working on?

This is only protection.  It is painted :)

I think i found a solution, its really comes in a game where you need to go over obstergoals, and then i juse that tactic, but to the subtjek. http://img208.imageshack.us/img208/9208/60319307.png There you see the front, that it does is when it hit the first wheel then it will lift up, but you need some thing to hold it, but you need lots of power. Then i put that arrow to see that when the secound wheel hit then you got exstra power....


Hope THIS helps :)

It works.

I must still nice edit.

This is a good idea. I must try it. :)

Traction is absolutely the problem.

If you don't have stickier rubber wheels, how about adding some rubber belt tracks? Having said that, you need enough weight to make the rubber belts effective, but if you must add weight, add it only to the centre of mass, not to one end or the other...
