A demonstration of the traction control software by team 121:

Good luck everyone!

The difference: BIG!

What kind of feed-back are you using? Encoders on the tough boxes?

Is there some kind of “mechanical traction control” (under gearing) as well? What ratios are you running?

Woody1458 · January 31, 2009, 11:13pm

what method are you using for slip detection? I’m assuming since u were mentored by 148 it is a ground sensor vs motor encoder?

Akash_Rastogi · January 31, 2009, 11:17pm

Woot!

Ours is working well too. Great to see that you guys are performing the same as well.

Seat_Ninja · January 31, 2009, 11:18pm

Nice. Is that programming only, or are there some accelerometers in there?

EDIT: wow like 5 posts at the same time

So what kind of weight is on that robot in the video? and how does it do with pushing something?

Chris · February 1, 2009, 1:08am

It’s week four,

Shouldn’t you guys be done the whole robot by now?

R.C · February 1, 2009, 2:21am

No, not really. Well we aren’t, but we will be done by this upcoming Sat.

Michael_Corsetto · February 1, 2009, 2:27am

I believe Chris is referring to how quickly 121 had a competitive robot last season, it was on youtube and scoring in week 3. Just slightly intimidating

Akash_Rastogi · February 1, 2009, 2:29am

121 is one of the beastliest teams that uses the kit frame. They are fast and efficient.

R.C · February 1, 2009, 2:47am

I should so join a east coast team.:rolleyes:

Sean_Raia · February 1, 2009, 10:18am

Nice. Was it hard to implement the traction control?

sybert1ger · February 1, 2009, 1:01pm

While we are not as far ahead as we were last year, we are still making good progress.

MOE · February 1, 2009, 2:34pm

HELLOOooo from the North East to the North East
Yep its me old MOE your bot looks great:yikes: , But what else would be new as you always have one of the best around. Keep up with the super job and WE will meet up some place I am sure… Good Luck to all the teams and see ya sooooon !!!:ahh:
MOE and Team 88 TJ2 oh yeah ??? OH YEAH !!! TJE DYE for ever…

If this doesn’t sell teams on the advantages of traction control, I don’t know what does.

Boydean · February 1, 2009, 4:23pm

Thats pretty awesome. I have one question though, what kinda feed back are you using from the robot to use your traction control off of. We have some ideas and want to see how others are doing it.

gorillamonky · February 1, 2009, 6:27pm

Can you explain what you mean by traction control? Like, what was different between traction control and non-traction control?

gorillamonky · February 1, 2009, 6:28pm

What surface are you using? Is the the real “regolith” material that will be used in the crater?

Andy_L · February 1, 2009, 6:29pm

Traction control basically senses if your wheels are spinning and if you’re moving. If the wheels are just spinning and you aren’t moving it slows the wheels until the robot starts to accelerate.

And yes, it appears to be regolith from what I can see

How did you do it? I’m asking all teams with working traction control. I see traction control threads, but as of yet I don’t see one where someone says how they successfully did it.
