Re: CVT, which teams are planning on using them for next year?

You're right Mechanicalbrain. Sometimes, it would be nice to have a computer control it, but then for driving, it's not that hard, so a driver can think about other things too. I was on the drive team this year and I had also been to go in and out of turbo very easily without really having to think about it and concentrating on it.
There are also some flaws if you have it controlled automatically. Sometimes, you may need to quickly switch to a higher torque setting while the robot is about to go into a pushing match, and if you hit the other robot at high speeds, maybe the sensor might get damaged and so the gearing has the chance of staying in the same position and it will not change your gearing for when you go to a stop and chances are you will be pushed around, while a driver that can manually override over it can start gearing it up so that you have more torque going into a pushing match so that you can possibly win. Something like this actually happened on our robot this year. We had a limit switch to detect when the arm is too high, so the motor powering the spool that pulls the cable stops. During one match, it had gotten damaged and we were not able to lift up our arm at all during the whole match just because of that. But also Cory, how you said the future is autonomy, robots aren't perfect yet. It would be nice to have it controlled automatically, so you are correct, but at times, a manual would be better.

And if the problem comes to it that a driver starts getting nervous because he forgets how to control it, he should've maybe practiced somewhat before to get the feel of which buttons or however layout you're going to use, and also the layout of the control board plays a part into it. The driver should pick out the buttons for which function on it so that it is easier for him to drive.

That's just my two cents and my opinion. Just so ya..
