Micro ROS on the Pololu 3pi+2040
The Pololu 3pi+2040 is a very capable (and adorable) mobile robotics experimentation platform sporting the powerful Raspberry Pi RP2040 microcontroller. The ROS 2 robot operating system is the standard platform for mobile robotics, providing reliable publisher-subscriber communication, simulation and visualization. … Continue reading
Generative Art & Pen Plotters
Just operating my 3D printer have become a bit boring, so I’m interested in other uses for the gantry. Attaching a pen to the gantry to make a simple pen plotter seems like a worthy project. The plotting area will … Continue reading

Indoor Mobile-Robot Localization
The RomiPi project currently uses Aruco Tags for localization! While highly accurate, there are several limitations: cameras and vision are expensive, and visual obstructions limit use of cameras for certain carrying tasks. This pose will document various technologies and products … Continue reading

Introducing RomiPi: A ROS Package for the Pololu Romi
The Pololu Romi with 32u4 Control Board is a robust, low-cost (<$150), educational robotics platform that supports interfacing with the Raspberry Pi computing platform. The Robot Operating System (ROS) is a robotics framework used throughout academics and industry which supports … Continue reading
Bigger Buttons for the Pololu Zumo!
The Pololu Zumo 32u4 is an excellent educational robotics platform, but its buttons proved difficult to manipulate for some of the students in my classes. I designed these bigger buttons as an add-on for the Zumo. My hope is that … Continue reading
