DPRG Monthly Meeting – LiDAR and ROS2 (oh my!), The Maker’s Pet Robot Kit – 3/28/2026

The DPRG will hold its March meeting at the Dallas Makerspace this Saturday Mar 28 at 10AM. There will be a buzzer on the door to admit attendees to the Makerspace. All are welcome to attend the meeting.

The meeting will feature a talk by the creator of the Maker’s Pet robot kit. The Maker’s Pet is an inexpensive differential-drive robot with lidar and turn-key ROS2 software. It can map its environment using the ROS2 SLAM package and navigate within the generated map.

Turn-key” and “ROS2” aren’t usually used together (though often promised), but thanks to the innovative use of docker containers and excellent build/operate videos and documentation, this robot is super-easy to get going and make maps and navigate flexibly within them. Several DPRG members have built this robot. In fact, this post’s featured image is a photo of Mark R.’s robot.

Pizza will be served at Noon.

ARM based Subsumption – Monthly Meeting Topic – August 11th, 2018


DPRG’s monthly meeting for August is on Saturday, the 11th, at the Dallas Maker Space. The meeting starts at Noon.

This month, long time DPRG member David Anderson will review recent upgrades made to his infamous “leaf blower” RCAT robot. Dave has completed a port of the robot’s subsumption architecture and LMX, a light-weight cooperative round-robin multi-tasking executive, to an STM Nucleo F411 board. The result is a dramatic improvement in performance. David will also highlight a custom printed circuit board, a joint effort between Ron Grant and David, that facilitates signal and power breakout for clean wiring layout. David will provide details on how to obtain a copy of the board.

As part of the presentation, Dave will also touch on the subsumption architecture used in this and many of his competition winning robots.
