RoboColumbus-2025: Results, Robot Interviews, and Run Videos

DPRG’s RoboColumbus Outdoor Rover competition for 2025 was held on November 22. The competition was hosted by the Edward’s family, which is greatly appreciated by DPRG. The morning started out with the course layout. Donuts and coffee were provided for the judges and competitors. While the course details were finalized and the cone waypoints handed out, competitors made final checks on their robots and used the practice cones to set up vision systems. At midday, pizza was served, then the competition started. Each competing robot was allowed 3 runs. Winners were based on the best runs of each robot. Everyone had a good time.

Congratulations to Scott Gibson, who achieved a Perfect Score in a Human-Planned run (unlimited waypoints) and a 6 in the 3-waypoint challenge.

Robot run videos are very helpful in showing the unexpected tribulations that the robots endure while attempting the tasks of the competition. Even runs that did not go well often have lessons.

DPRG Monthly Meeting – Using Git and GitHub and AI Generated Movie – 10/25/2025

AI Generated Meeting Summary:  Meeting Summary (PDF)

DPRG’s October monthly meeting was held at the Dallas Maker Space on October 25, starting at 10:00 AM.

The meeting this month was a double-header talk.

DPRG member, Paul Bouchier, completed a talk on Git and GitHub originally scheduled for the September meeting. He explained why individual robotics developers would benefit from using these tools. The talk covered how to get started, how to perform frequently used operations, and common scenarios.

Guest, Thomas Messerschmidt, showed and discussed a movie he made using AI. The movie’s plot is an interview with an AI that went badly off the rails. This should be a fun watch.

After a pizza lunch at Noon, the floor was open for a “Show and Tell” session.

    • Scott showed his Robocolumbus robot, Belch
    • Paul & Mark showed improvements to the Makers Pet robot
    • Eric showed improvements to his robot

DPRG member, Karim Virani shared his experiences building a voice and video interaction mode for his Pioneer 3 chassis-based ROS2 robot, Barney. The goal is to combine chat and command modes into a responsive unified experience for operators as well as bystanders. According to Karim, there is also a dark side …

Karim did not focus on the AI-assisted software development process so much as how to use AIs for this specific purpose. He also has a Git repository at https://github.com/pondersome/by_your_command.

The meeting was held at the Dallas Maker Space on August 23 starting at 10:00AM.


DPRG Monthly Meeting – Show and Tell – July 26, 2025

The DPRG monthly meeting for July 2025 was a “Show and Tell” event. Members brought their projects and talked about robots.

It was a golden opportunity to see progress on various projects that you hear about during RBNV and on the Discord channel in person.

Pizza was served at lunch for all attendees.

DPRG Visit to RobotLAB – 06/28/25

DPRG Members and friends toured the RobotLAB facility and had a chance to mingle with the robots! They were able to see about 20 different robot types that address different market segments. It was a great opportunity to see a wide variety of real robots that get to be deployed in customer environments. After the tour the group was able to share lunch with the hosts. A good time was had by all!

Power Lunch – 6/15/25

On June 15 DPRG held a Power Lunch at the Derbyshire pub in Frisco. The event was attended by about a dozen DPRG robot-heads. There was good beer, and good English food, and lots of talk about robots and AI.

DPRG holds a Power Lunch about once a quarter. Make sure that when the next one is scheduled that you plan to attend. They are fun and provide a lot of person-on-person conversations. Watch the website and the Discord channel for details of the next event.

AI Generated Meeting Summary:  Meeting Summary (PDF)

Join DPRG on March 22, 2025, 10:00AM CT, at the Dallas Makerspace for a presentation “ROS2 Navigation and Linorobot2” by DPRG member Paul Bouchier.

Presentation overview

  • Why ROS2 navigation? ROS2 is the most widely used robot SW platform, and it has a powerful map-based navigation system.
  • Why Linorobot2? Linorobot2 is a very flexible, open SW configuration built on top of ROS2 which enables hobby-level mobile robots (< $150) to use ROS' map-based navigation stack with zero to just a little programming depending on what you want to do.
  • Paul will explain ROS’ navigation concepts and how to configure your robot as a Linorobot and demonstrate how to use ROS’ navigation system.
