An example of a map built autonomously by Spinoza is shown in
Figure 10. The grey regions of the map represent
areas unseen by the robot. The white regions are areas where it is
known that no obstacles exist, and the black regions are locations of
known obstacles.
This map was made on a 
grid, each grid representing a
cm square. The robot was able to autonomously explore
and map out this region in less than 10 minutes.
