Thesis v0.04

Notice the white dots over the laser (might be hard to see), they follow the main laser (not the reflection). I can use a single laser profile to detect steep slope changes in that plane slice. So using just that, the robot can identify the drop-offs on the sides of a ramp or the ends of a wall.

To differentiate between a wall and a ramp, however, profiles from various positions must be compared. And that's what's next... Just have to put this on wheels!
