FIGURE 9-8: Paper canvas laid out and secured

Trying It Out
With canvas and brushes in place, you can quickly test the mechanics of everything by telling
Roomba to do a normal cleaning cycle. The Spot mode is most interesting as it immediately
starts an expanding spiral. Figure 9-9 shows that spiral done twice, from slightly different start-
ing positions. The little squiggle on the right side of Figure 9-9 is what it looks like when you
keep tapping the bump sensor of Roomba.

You can read more about the Spot mode and other modes in Chapter 2.

Be sure to watch Roomba and make sure it doesn’t stray off the paper. If it starts to, just pick it
up and move it where you want it.
