Go to Post Temp wiring is always bad but it is made worse when dealing with a $1000 part. You wouldn't try to lash a makeshift power source to your PC. - Al Skierkiewicz [more]

Re: 2809 - Traction Control Demo

Does your ystem work for acceleration as well, or just shoving? It would be nice to see a comparison of acceleration with and without TC. The pushing thing--it looks nice, but have you collected more empirical data than "he stumbles back more with traction control on"?

If you listen to the audio on the video you can hear the traction control at work. With the TC off you can hear the motors whirring away and the wheels spinning even when the robot is held stationary. With the TC on you can hear that the sound is very different, the wheels are not spinning even though the robot is being told to go forward, but held from doing so.

Re: 2809 - Traction Control Demo

Yep, the robot is just pushing, and will even compensate when you push back on it. The issue we found is that once you start slipping, it's really easy to move you around.

Hopefully we can get another video up when we test on the playing surface tomorrow.
