I do not have the resources to actually try this out for myself, but if
somebody here wants to try this, I'd be interested in knowing if it works.
The walls of the area are to be painted solid black. Several coats of
paint may be necessary to absolutely minimize reflectance. The cans are to
be painted with a highly reflectant bright colored paint. Good overhead
lighting should be used to maximize the amount of light that is reflected
from the cans. The floor of the area should have a custom paint job on it
as follows:
The floor of the starting area is to be painted white.
The area of the floor within 6" or so of each wall is solid black, with
the exception of the area within the startiing corner.
The remaining area of the floor is to be painted with a gradient going
from light to dark such that the closer the point is to the starting square,
the brighter it is, the closer to a wall other than in the starting square,
the darker it is.
The 'bot should have the active light sensor pointing downard, and be
configured so that the IR sensor is facing forward. It should be built so
that it can turn left and right. There must be a mechanism on the 'bot for
detecting that it has actually come in contact with a can (either physical
mechanism or software), and a means for grabbing it, and putting it in a bin
carried with the bot. The bin must be able to contain all 3 cans.
The program works this way: starting in the home position, turn to find
the direction of the maximum brightness by "pinging" with the IR
transmitter. The direction of maximum brightness should be from a can.
Once a can is spotted, proceed forward, adjusting the direction as necessary
whenever sight of the bright can is lost. The bot should grab the can,
place it in its bin, and search for the next can. Once all 3 cans are
found, the 'bot can proceed back to the starting position by following the
gradient pattern on the floor, trying to maximize the value seen by the
light sensor.

| We've talked a lot about theory on this list, but how about an actual project contest? I propose a contest. Be the first to create a robot that can enter a room with no obstacles (other than walls), find a randomly placed coke can, pick up the can (...) (26 years ago, 23-Feb-99, to lugnet.robotics.events)
