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.
Results:
| Competitor / Robot | Run 1 | Run 2 | Run 3 |
| Scott Gibson / B.E.L.C.H 1st place – Perfect Score | ⭐9⭐ (5:37 + 2min penalty) | 3 (3-wpt Challenge) | 6 (3-wpt 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.

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.
