I did not see anything in the rules excluding beacons.
On the can end, the current rules mention substitution the white course can
with a can of another color or a "B-can" of your own design.
If you would like to put a home base beacon up, who will stop you?
If contest rules become overly restrictive on how you do a task. They really
should be examined.
Also, if shorter walls in Can collection killed the opportunity to use
sonar, maybe that should be examined against visibility and transportability of a
contest course -- or hold contests at the warehouse and invite use of either
course.
I should mention the goal in single can collection concept was to speed the
contest and reduce its complexity. I am sure David Anderson spent some time
adding the ability to do position re-calibrate (odometry referencing robot) --
I know I did, when I attempted to do that on a fire fighting robot using
video analysis of a wall floor border.
Orange cans are easy to see if you are using video. If cost is prohibitive,
I would recommend going after beacon technology. Dale Wheat was pushing on
beacon design earlier this year -- cheap!
At last months meeting, David Anderson proposed contests that would tend to
encourage development of odometry skills + big help for most everyone.
I wonder how well David's SR04 would perform Can Can without use of odometry?
Odometry is a king, I caught on to that fact real quick when I joined the
club, never mind all the distractions off into 3D simulation land and speech
I/O that have overcomplicated my software..
I guess too the dual benefits of motor encoders being useful in controlling
motor speed and measuring distance traveled with little sensor lag and not
much "noise" when on a smooth surface & not slipping , make that technology
important to master.
IMHO, We really need to encourage learning and implementing that skill in
our robot builders.
Also, beyond all other skills, teach the most important, DIVIDE AND
CONQUER.
