In robotics class, we are building robots that can find “packages” (a cube with an IR LED in it) and return them to a drop zone. To make the drop zone find-able by the robot, we would like to use an IR beacon. To make the drop zone distinguishable from the package, I’m assuming we can make the IR at the drop zone flash a unique code (using an arduino) and have the robot look for that code once it has a package. The package IR LED is a steady-on.
Is this the right approach? If so, what would the code for the beacon look like? How about the code to find the beacon?
