Practical LiDAR for Hobbyist Roboticists

Scott’s slide deck: slide deck (PDF)

Followers of DPRG’s competitions are familiar with Scott Gibson’s very successful robot CanMan. CanMan utilizes a spinning LiDAR manufactured  by RPLidar (~$100). 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.
