they can come down again after the mapping is complete.
- could a very few reference points be used to create such a map?
- what laser system could be used given that it's only looking for a very few reference points?
- how much processing power is this likely to take?
- The purpose of defining a map whilst the stickers are up is so that fixed points on the map are identifiable to the robot when it encounters them after the stickers come down e.g. a tree, or a swing. This will help the robot with localisation issues and help remove errors of spatial awareness. There might be 100 fixed points that would be incorporated into the map under the umbrella view of the stickers i.e. this could be done without the stickers, but the stickers and a reference to them would reduce the error rate in establishing the map and its boundaries.
- What type of sensor system would be useful in this situation?
- How much memory would be needed to do this on the fly as the robot was moving around?
When the preliminary map is completed the robot will know the location of quite a few numbered markers.
The robot starts at a base so knows its (0,0) position.
All of that depends on it having an accurate map to start with, hence the stickers and spacial construction process.
10 cm cubes would be about right though possibly as small as 5cm2 Lawn sizes up to 2000m2
By the pattern of the magnets sensings, combined with the sensing of the perimeter wire, along with the sensing of any bump/proximity sensors - all of this information should be enough for the robot to determine its position and orientation via a SLAM algorithm.

Magnets were not something I had considered; I was thinking more along the lines of BLE each with a unique ID though obviously powering these then needs to be built in to the solution, and adding in BLEs also adds in $s.
