DPRG Monthly Meeting – “Hack-a-Bot Challenge” – 8/22/2026

Posted on by

The scheduled tech talk speaker for this month’s DPRG monthly meeting had to reschedule at the last minute. So, our glorious leaders have cooked up something a bit different (and a lot of fun) for this weekend’s meeting.

With details intentionally vague, the event is DPRG’s first “Hack-a-Bot Challenge”.

The concept is simple. You’ll split into teams, be given a goal, work together on the project, and then after a couple hours work and some pizza, we will test your creations in a death-defying contest (for the bot!)

The only heads up I can give is that soldering will probably be required (bring one if you can, we will have a couple on hand otherwise), construction with cardboard, hot glue and duct tape a strong possibility. A few hand tools would also be advised. Microcontrollers will be optional, and 3v will be all the juice your franken-bot gets.

We will live stream as usual for our remote members so that they can enjoy the mayhem.

See you on thw 22nd (Saturday), at 10am at Dallas Maker Space!

Everyone is welcome!

Post Event:

For the competition, each team (locally, there were 5 teams of 3-4 persons/each and 2 remote competitiors) was given an inexpensive line-following robot kit that used a cross-comparative circuit that drove the motors using a simple transistor driver. The kit had two light-dependent resistors (CdS) sensors illuminated by LEDs to detect the edge of the line. Kit Amazon link is https://www.amazon.com/dp/B07ZH4XLQ3?ref=emc_p_m_5_i_atc&th=1 .

The challenge was to build a robot that could knock two plastic cups off a table, keep the robot on the table for 30 seconds after knocking off the cups, and stop. Scoring was 1 point for each cup removed from the table, 1 point for not following off the table, and 1 point for stopping. All the teams achieved 3 points, except for one which received 4 points. Some of the teams had to troubleshoot a PCB defect that prevented one motor from running. The event ran from 10:30AM to 2:30PM with pizza served while working. Everyone one enjoyed the event and learned something.

DPRG at Moon Day – 7/18/2026

Posted on by

DPRG shared a presentation area with Iron Reign FTC 6832 team and Lovejoy HS’s VEX robotics teams 1082B and M at this year’s Moon Day event held at the Frontiers of Flight Museum near Love Field in Dallas.

It was the first appearance of DPRG’s 7-foot Robie mascot with improved neck mechanics and facial recognition at an event. DPRG presented an array of robots for event attendees to see and ask questions about.

Iron Reign showed one of their FTC robots and had a 3-D printer setup to produce moon and space themed earrings and key chains that they distributed to event attendees.

The Lovejoy VEX robotic teams demonstrated two of their competition robots and displayed the multiple awards that they won this year in state and regional competitions.

All three exhibitors were busy all day sharing information to event attendees, from young to old. A great time was had by all.

DPRG Monthly Meeting – ModLinker: A Different Approach to Robot and System Design – 6/27/2026

Posted on by

DPRG’s monthly meeting for June was a presentation by Mark Dombrowski on ModLinker

Presentation Summary:  Meeting Summary (PDF)

ModLinker is an attempt to create a set of tools for making modular hardware systems, like robots, simple to create, reuse, scale, and share. The talk will be an introduction to the system followed by a request for beta-testers.

The beta version of the system is based around Raspberry Pi Pico microcontrollers and MicroPython. It is designed to be simple enough for beginners but also allows features for more advanced users.

DPRG Monthly Meeting – Unitree Go2 Robot dog (and maybe more…) – 4/25/2026

Meeting AI Summary

The April monthly DPRG meeting featured a presentation by Sensori Robotics, who demonstrated their Unitree Go2 Robot dog. It was a chance to see a robot “dog” go through its paces. Sensory Robotics also discussed their pivot from robotic mowers to building research-focused, wheel-based, bi-manual humanoid robots that use physical AI software. Ross Melbourne explained that the shift to Vision Language Action models and zero-shot learning is driving massive funding toward humanoid robotics.

After the presentation, Sensory Robotics had a give-away of excess inventory from the Robotmow mowers that they have liquidated. The give-away included brushless DC motors, wheel motors, mower wheels, and various other parts.

The post meeting show-n-tell which is always an interesting time to share ideas. Tnis month’s show-n-tell included a demonstration by Jason of his animatronic robot prototype, ‘Endoskeleton’. Also, Mike Williamson made robot runs of his 495-gram sumo robot and his ROS barrel racing robot. They performed very well.

A pizza lunch was served after the meeting. Next month is Roborama!

DPRG Monthly Meeting – Show’n’tell, Swap-meet, Plans for Robie – 2/28/2026

Posted on by

The DPRG will hold its February meeting at the Dallas Makerspace this Saturday Feb 28 at 10AM. There will be a buzzer on the door to admit attendees to the Makerspace. With the holiday season and the club’s annual meeting over, it is now time to start to build robots.

The agenda will be:

  •  Show’n’tell. Bring your robots to exhibit, demo, and talk about. This is great motivation to start this year’s project.
  •  Swap-meet! Bring anything you don’t want that you think someone else might. Be prepared to find stuff you want. This is a good opportunity to do some spring cleaning and concentrate your robot building efforts.
  •  Robie repair/upgrade brainstorming & planning. At the annual meeting it was proposed to start up biweekly in person work meetings to repair and upgrade Robie as a club project. Ideas and help are welcomed by anyone wanting to make him even cooler.

All are welcome to attend the meeting.

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

Posted on by

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
