VRC 575 Running Its 43-Point Auto

This is a link to video of 575s 43 (sometimes 44) point auto routine. In this run, they actually scored only 37 because a cube bounced out of the fourth goal, but you'll get the point. The team wanted a second run for the video, but we had a lot of stuff to do and just didn't have time.

Link: http://www.youtube.com/watch?v=rqovGM8Tl7Q

Scoring: Six goals, eight cubes (sometimes nine) in goals, bonus cube knocked off.

Interestingly, since the line following code accelerates the robot if the error on the line is small, the routine always takes a different amount of time, ranging from 56 to 64 seconds. I believe this example runs about 61 seconds. They've tried speeding it, but it loses reliability. Having seen dozens of robots running Elevation for a one-minute auto at Dallas, I'm thinking 43-ish is simply the most you can do in one minute. In Dallas, 575s 37 was the highest total run, with second place doing 30.

Well done if our line following was anything to go by, this must have taken a LONG time to programme

Re: VRC 575 Running Its 43-Point Auto

Wow, that's something to shoot for. One of our goals is to actually try and implement a line follower for this year's competition.. there are so many lines.. and so few ramps...

Re: VRC 575 Running Its 43-Point Auto

On behalf of this team, thanks for the kind words.

Here's a link to 418 goofing around today at our meeting: http://www.youtube.com/watch?v=Zn6ZQ12e1vg.

That arm extension is something they normally only used for the Robot Skills Challenge. I'm always blown away by how well they drive this robot.

You know your robot is too fast when it doesn't have enough torque to push a swivel chair.

Re: VRC 575 Running Its 43-Point Auto

Hi Rick.

That is a very good example of line following.

How did you allow for the different light levels on the field at different competions?
Do you have a pre-match initalisiation routine to determine the white tape - tile difference?

I want to get our team trying a line follower routine this season.

Dang, how many line sensors did you use?

I had nothing to do with it -- but they use five.
