Chapter 9 — Creating Art with Roomba 177
If you want to ensure the Roomba stays within the canvas, make a frame out of lengths of cheap
2 × 4 lumber. You could nail or screw the 2 × 4s together or even just lay the loose 2 × 4s at the
canvas edge. If you modify your code to watch for the bump sensors you could even have it
bump of the frame in artistically pleasing ways.
To make Roomba more stable and less likely to smudge the line it’s drawing, remove the Roomba
brushes and brush guard.
