Stair Climbing Robot Designs to Prep for 2024

Seems like there would be a bunch of scrub with that setup, especially with “reasonably grippy wheels” - how do they actually perform wrt turning on carpet?

Some of the teams in these examples expressed having this problem.

From the third example:

@Road_Rash

We never got our tri-wheel drive to work correctly, either. It looked like James Bot was having a seizure anytime we tried turning

And the last example:

@rebelreyek

Why the omni wheels? It would seem to be that you would have no control over when the omnis were touching the ground, because any time you cross a defense the configuration will change. Couldn’t this lead to inconsistent traction on the drive base?

You’re right; our wheels flip while going over obstacles and we have don’t have a way to control it. However, we prototyped and tested with all three wheels as traction as well as two traction and one omni. We decided on this configuration because it gives us more maneuverability, and after adding (somewhat excessive) weight to our prototype, it became difficult for us to turn.

There was also a 2004 bot where the entire thing was essentially a box with one set of three wheels on each side, 1218 I think.

Yep, came across it last night:

Looks like the rotation of the tri- was motorized independently from the rotation of the wheels, unlike the other examples.

Also, one more example:
