Well, you got me beat - I’m running around 40 cm/sec on my course (4+ meters
with at least 16 6” radius turns, including a “L-R-L-R” section as well as a
couple of “R-L-L-R” sections. And even then, it still looses the line on rare
occassions (it has a “detect and refind” routine that works pretty well).

Unfortunately, this robot has hit its design limits.

Mine hasn’t, but then again, this is my “one size fits all” entry. It’s really
designed for the line maze (at a significantly slower speed, I fear - I really
like accuracy). I was planning on a rack-&-pinion or at least front-wheel
steering system for the basic course, but I’ve run into an interesting problem -
I’m almost completely out of light sensors. I can swap RCXs around between
robots, but swapping the light sensors is a lot tougher (they end up built into
the structure much more). So far Trellis (general line follower) uses three, and
I’m working on two mini-sumo robots that will each need at least two (perhaps
more). I’ve got to locate any others I have built into stuff.

Ben Hur... driven by two RC buggy motors.

Now that should be fun! If it doesn’t work on line following, let’s have a
robotic demolition derby.... ;-)
Are you using BrickOS?
On other ChiBots issues, making a pure-LEGO sumo that’s under 500 grams and
fits in a 10 cm x 10 cm footprint is... interesting. The RCX is 10 cm long all
by itself.

| Well, I may not be competetive yet for first place. But, I am pretty happy that I am running a robot around a 5 meter track with lots of S-curves. And, the robot is doing laps at 55 cm/sec pretty consistently. Unfortunately, this robot has hit its (...) (19 years ago, 23-Oct-05, to lugnet.org.us.laflrc, FTX)
