Our third Italian Legofest featured a funny dragster race. In brief, the
dragster had to be built using just Lego parts (except batteries), use up to
3 motors, 1 light sensor, and run at its best on a 5m distance delimited by
black tape. The main constraint was that it had to stop in 20cm after the
finishing line, otherwise the run would have been declared null.
I personally thought this challenge was even too simple and not so
"robotic", but it deserved some unexpected difficulty and taught us many
interesting things:
- How to time the performance with a resolution of 1/100s using the built-in
1/10s RCX timers.
- How to stop a vehicle that's running at 1.6m/s (5.3ft/s) in just 20cm
(less than 8in).
- What kind of batteries give better results.
You can find some detail, pictures and NQC code at the ItLUG site:
http://www.itlug.org, follow the link to the Events page and from there to
the Legofest III, Dragster race (text both in Italian and English).
If you have any further question not answered on the web page I'll be glad
to help.
