Chapter 7, Avoiding the Stairs

1. LIDAR, a type of laser radar, is the most common SLAM sensor used, by a wide margin. The 3D data that LIDAR provides is perfect for SLAM’s mapping function.
2. The Wheel odometers reduce the search space that the SLAM algorithm needs to look for possible locations of the robot after moving. Thus, it increases information and reduces uncertainty in the map.

3. It reduces noise and gets rid of stray single pixels in the image, making for a smoother result.
4. Instead of using radial red lines, the program can just draw upwards from the bottom of the screen in a series of vertical lines.
5. We just want to use the upper half of the room to train the network because the lower half has the toys on it and are subject to change. ...
