This probably qualifies as my first real robot. Still works after 20+ years. I built it as part of the final project in my grad school Artificial Intelligence course. The professor made sure I understood the project was a software project, and not to get hung up on the hardware side (fortunately, being an electrical engineer in […]
What do you do with some scooter chair motors, big casters, and a sheet of MDF? Make a radio controlled Yard Bot of course! I’ve had the various pieces for this project kicking around for a while. Finally took the time to put them all together. Just something to play around with…
Very rough video instructions are now available on my YouTube channel.
A PDF template for the 2020 Bot can be found here. Source code for the 2020 Bot can be found here. Read more for the parts list…

I’m seriously considering whether or not it makes sense to offer 2020 Bot kits, or just provide instructions and let everyone fend […]
Experiments continue on the 2020 Bot! The robot on the left was built using the ubiquitous 28BYJ-48 geared stepper motors and ULN2003 drivers. The robot on the right uses the famous yellow gearboxes plus brush motors with an L9110S dual motor driver board. Which one should I use for the 2020 Bot?
Slides from my 2020 Bot presentation to the Nashua Robot Builders. The 2020 Bot is a work in progress…
Well, the EB1 has actually been around a while. It’s the brain child of Tully from Samurai Circuits. A few years back he tried to convince me to work on an inexpensive Arduino compatible platform that could be used for teaching electronics and programming, but without needing a lot of extra pieces (like a breadboard, […]
This is a short presentation about robot kits I gave at a Nashua Robot Builders meeting.
To get started with off the shelf robotic kits, there seems to be a price threshold of about $50 for a bare bones ugly hack-kit.
