Team 968 Traction Control Demo
Here's our traction control demo that we performed a few weeks ago.

Re: Team 968 Traction Control Demo
Nice side by side comparison. That just goes to show the importance of having traction control this year.

Re: Team 968 Traction Control Demo
Very cool. Nice implementation, well documented results.
Kudos, programmer... whomever you are. -q |

Good job, RAWC! I look forward to scouting you in San Diego.
Effective traction control coupled with a good ball dumping system will make your team "devastating". |
Re: Team 968 Traction Control Demo
The only reason I personally do not like traction control is because of pushing other robots, or your robot getting pushed, then you are kind of screwed. I think the best way of performing this year will be a team who has traction control, but can still turn it off if they need to.
and Great job! We tried doing traction control but we decided against it. |

If you completely stop moving your robot you're still going to have those 5 seconds where the robot will start moving slowly and gradually pick up speed. |

If you have a traction algorithm that increases/decreases power output in relation to the amount of wheel slip, you would actually be able to accelerate and decelerate much faster; which, in turn, makes it easier to "defend from other robots pushing you". Also, with TCS, you'd have a better chance at pushing objects on the field. If you grab a stack of books and have your robot push against the stack while running your wheels at full speed, you'll move no where in a hurry. On the other hand, with TCS, you'd push the stack away at the quickest rate your wheels can spin without slipping. |

Re: Team 968 Traction Control Demo
The Vid is like down or not available, could someone please re-upload this.
EDIT EDIT: IT WORKS NOW, I DUNNO WHY? |
Re: Team 968 Traction Control Demo
A technical question: do you have any sensors to see if your wheels are slipping, or did you just hard-code in empirical values for max acceleration and deceleration?
Very nice, I like it. Saw that bot in blue yesterday, should be a real threat in either color. |
