Re: Team 121 Traction Control
 

If you listen to the audio, the operator was directed to turn off traction control as a comparison. When it hit the wall, the traction control was disabled.

The software allows a certain amount of wheel slip when the operator is attempting to turn.

The trailer was loaded with enough weight to simulate a fully built trailer (36 lbs i believe it was).

Good Luck!

I'm curious how the traction control feed back will work when the robot is being bumped by another bot. Does the control loop stay stable. Have you tested it yet.

Re: Team 121 Traction Control
 

can you post your coding, or at least post an "untuned" version our team is having trouble finding the right direction. any help would be appreciated

Re: Team 121 Traction Control
 

It is boarder line ridiculous to ask for a team to post their actual code, keep in mind this is after all still a competition.

Tom already posted a link to an academic paper with great information in it. Start by reading that and try applying it to your code. If you still have problems then try to ask specific questions either here if they relate to 121's system, or in the programming forum.

Re: Team 121 Traction Control
 

Why don't you start off by thinking about what to do before you try to code. From my understanding of everything, keep in mind I didn't read the pdf link, you want to start off by reading what your encoders are telling you vs what your encoders from your trailer wheel are telling you. Then using 121's formula they generously posted, figure out your slip. Now try and figure out how to reduce that slipping. Throw that in a loop and I think you would have a basic traction control system.

That's really cool, but I was curious for all those with acceleration based controls. How well does it work when you do get in that occasional shoving match? Or if someone "speeds you up"?

wait..what kind of traction control is that? wat u guys using?
