Homing algorithm for robot

[No22Ben]

Hi guys,

I'm currently working on a vacuum cleaner project. (Arduino based)

One of the specification proposed is that the robot is able to return to the base, after the cleaning process is done.

Is there any recommended approach or algorithm for doing this ? (For eg, IR ?)

It will be great if there's any relevant tutorials / links provided.


Appreciate for your guidance

There are maze running robot mice, which go down every alley and avenue, then calculate the correct path flawlessly. It may be possible to program your robot to keep track of every maneuver it makes. It's a very tall order, however.

To use light, you'll need to shine a beam in all directions, so your robot can see it from all directions. You can spin the robot to search for the beacon, or, install more than one photosensor.

For IR to work you also need a clear line of sight and no reflections.
