You must: Build a car that can be remote controlled around an obstacle course. Best time wins! If you touch your car, or you take longer than one minute, you are disqualified from that attempt. You can have as many attempts as you like, but always in turn, if others are waiting. Your best time will be the one that counts.
Tips For students
Tip: Cars that use gears will go faster. A big gear on the motor and a small gear on the wheel will make the wheel turn faster. The wheel's axel must be not go through the motor's hole.
Grading option: Students are timed to complete one lap of the course. If you are timing each robot, make a copy of this Google Sheet to help you score. It's helpful to put a maximum time on an attempt if too many class members want a turn.
Additional Equipment needed
You'll have to make your own course based on any bits and pieces you have lying around. It's not a bad idea to make some sort of figure-eight track if possible. Good drivers should be able to do the course in under a minute.
Here is a course I made once, just using a bit of timber and table and chairs and other furniture.
The electrical tape was not a necessity but it helped the kids remember which way to go, and where the start and finish line was. (Between table legs)
Clipboards make good ramps!
In hindsight I probably had too much lego on the track. We ended up removing 90% of it. Some cars couldn't make it through the lego when there was lots.
I took photos of it so I could easily remember how to set it up for next lesson.
