Announcing a robot competition for BrickFest PDX...


The line will be a closed loop, using 3/4" black tape on a white surface. Each
line segment will be at least 6" long, and the sharpest turn will be 60 degrees.
Robots will complete three laps or circuits of this loop per attempt.

Robots that entirely leave the line at any point will be given an DNC (did not
complete) instead of a score for that round. Any robot unable to complete a
single circuit within a minute will also be given an DNC.

The main prize is for the fastest waiter. There will also be a second prize for
the "Best Dressed Robo Waiter". Note that the robot for this prize must be a
*functioning* robot! It must be able to carry a tray of balls around the course
at least once.


Good luck!

David,

I have a public question about the competition.

Will the robot need to know when and where the starting line (and therefore
stopping line) be located? Or will the robot simply need to carren he course
following the line?

What constitutes a robot leaving the line? Does that mean that the entire robot
goes off track? I could see my robot infrared eye leaving the line, but having a
search program to help it find the line again. Would this be allowed as long as
the robot doesn't leave the track?

Also, if the robot should get turned around and travel in the opposite
direction, will any three complete revolutions around the track count? Is there
a specific direction that the robots need to travel, i.e. clockwise or
counterclockwise?

Todd

(...) As Steve pointed out, (Thanks Steve!) the starting line will not be something that your robot will really be able to notice.
