Rotating track flipper design

I see a few of these tracked robots that have a set of tracks that pivot 360 degrees around. I'm kinda stumped on how to build the flipping thing while still using COTS motors and tracks. Are all of these completely one offs, using some kind of custom-built sleeve that controls the pivot of the track, while the drive of the tracks is connected in the middle of the sleeve? How does this work? I've hopefully embedded a video that has an example of what I'm talking about. If you search youtube for "stair climbing robot" you'll run across a dozen or so different robots that use this design.

Stair Climbing, Tracks and how well they work on carpet!

I am designing a robot that will be able to climb stairs in a similar method to a packBot.

However it is designed exclisvly for indoor use, which means carpets!

From my reasearch the basic impression i get is that i need smooth tracks with not much friction to be able to turn effectivly while on the flat. However when it comes to being able to climb stairs i will need tracks with large treads. Obviously two ends of the spectrum so somehow i need to find a balance!

Need advice about tracks

Hi all !

I am currently working on a tracked robot (electronics is finished, starting mechanics).

The tracks I am planning to build look like that :

I will you use the "pattern" described on many projects on LMR (the one using bicylcle chain, nuts...).

Bob is born

 

Well, thanks to not being allowed to alter Serenit-e's looks, I have a spare set of tracks & a dual-motor gearbox to work with - seems a shame to let them go to waste.

Bob is going to be a test-bed for trying out any new circuitry I come up with, such as controller boards, sensors, displays etc.

Just fixed some URLs to images, no real updates, this bloke has been disassembled for ages. This is my entry for the 2011 Swedish National Robitcs Championship. It … Read more
