yep... i think mine is the same speed (vid response above). maybe if we don't use the Syncing on the motors we could get some more speed with a good PID.
We are considering using the camera for a similar event at Robogames.
Your turning looks very smooth. Are you using a PID or similar algorithm?
Also, In your line following program, do you use all of the 18-pixel segments or just the topmost one?
I was thinking it might be possible to use all of the segments to estimate the curvature of the path, and change the robot's speed and turning strategy accordingly (i.e. gain scheduling).
Also, In your line following program, do you use all of the 18-pixel segments? topmost one only.
I had the same idea but finding a line (or curve) in a graph is difficult in NXT-G.(no floating point math) This program goes full speed on the straight part and reduces speed on the curves.
Also need to get program to follow a 90 degree corner and go straight on a cross. Then recognize when it comes to a T and pick a direction to go.
I think we will use RobotC which should let us do the FP math. Robogames will have at least one 90 degree corner so I guess we get to learn how to do that. Thanks for the info, and I'll keep you posted on our progress.
theres an nxt camera?????????????????

are you saying "bolt"?

The NXTCam works in RobotC too. I actually had it chasing the red and blue balls with RobotC last Christmas.

Are you using a PID? P (proportional) only.

nice! Have you tried this with intersecting track segments?
