Followers of DPRG's competitions are familiar with Scott Gibson's very
successful robot *CanMan*. CanMan utilizes a spinning LiDAR manufactured
by RPLidar (~$100
<https://www.robotshop.com/en/rplidar-a1m8-360-degree-laser-scanner-development-kit.html>).
In competitions where the arena is bounded by walls, CanMan's LiDAR allows
the robot to reacquire its location even after a collusion with walls or
other robots.

At the *October 12th* DPRG monthly meeting Scott is going to share how you
can add a similar LiDAR to your robot. The presentation will take a quick
look at the serial interface and data fields used by the RPLidar unit, and
then dive deep into how to use this data.

Scott will discuss the *algorithms and code* that he uses to:

   - Find the center of the arena,
   - Align to an arena wall,
   - Detect an outside edge,
   - Detect an inside edge.

This is a great opportunity to learn about how to use a spinning LiDAR unit.

*The meeting is at the Dallas Maker Space and starts at Noon on Saturday,
October 12th.*
