When

• August 4th, starting at 7:30 PM Dallas time (CST).
• RBNV will continue each Tuesday evening until the crisis is over and the Maker Space re-opens.

How

• Join Hangouts Meet https://meet.google.com/hey-jxuo-esf
• Or join by phone ‪+1 405-586-5598‬ ‬ PIN: ‪682 931 335 #‬

Why

• Talk robots & related stuff.
• Keep going while we’re stuck at home.
• Make it easier for people to attend DPRG remotely.

Agenda:

• Round table – everybody spends a couple minutes telling what projects they’re working on as we’re all stuck at home
• Ad-hoc presentations – Whoever would like to show & tell.
• “Stump the club” Challenges – Ask for help if you’ve hit a roadblock in your project. Somebody in the club can probably get you pointed in a good direction – or even arrange a side bar session to help.

Note: We record a video of these sessions and post them on the DPRG YouTube channel. By joining the meeting, you’re giving consent to be included in the recording.

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.
