Title: How To Avoid The Front Hitting The Stair First Before The Tread
Post by: Mastermime on September 14, 2011, 06:39:17 PM
Hello,

I am building a robot with climbing treads (where it is angled upward in the front) and a pyramid shaped front for blowing through things such as walls or other debris.  The climbing treads are used for climbing stairs and what not.  I was wondering how I would design my robot so the treads will hit the incline first rather than the pyramidal (Is that a word?) front, but when something such as a wall comes up, the front will still be able to hit the wall first rather than the tread.  Will I just need high ground clearance?  I am not sure.

Pics?

What I'm envisioning is that for the front of the bot, from the ground up to the height of a stair, the first thing encountered would be treads. above the height of the stair, the chassis would be encountered.

At the same time, why is this a problem?  Do you plan to mount a touch sensor (i.e. button) on the wall-hitting part of the chassis?  Or are you planning on driving around blindly and hitting stairs by pure chance? o_O

Sorry I do not have any pictures right now.  I am still in the designing process.

This robot will be teleoperated from my laptop.  The problem I am worried about is that the pyramidal (I'm just going to keep using this word  :D) front will hit the stairs first and the treads won't be able to reach the stairs.  Therefor making it incapable to climb stairs.  I dont know, maybe I am making up problems that aren't likely to occur.
