So @banjobrad2 Is that a five string or a four string? Tom

Well I finished a second prototype. This one is smaller with different motors, cheaper sensors, and a different MCU. The design grew from trying ...

@alextheprogrammer Hi Alex, I was wondering if you would use ROS or roll your own control software. I was all set to sing the praises of Joe Jone...

Alex, I noticed the same thing when I started reading this site in 2021. Our host worked out all the mechanical and electronic aspects for the ‘Rea...

Ron, Look what I came across today. Odometry and insect navigation Check out figure 4, a cruel experiment to be sure. Tom

@will thanks for considering my question. I’ll try measuring the voltage across the IR receiver and let you know if I find out anything interesting...

Well, @robotbuilder since you are a self-professed visual learner I will draw you a picture… But in the meantime, does anyone else have any idea why...

Ahh the Sharp GP2Y0A02YK0F. You realize of course that Sharp stopped making them. “End of Life”, robotbuilder. That was one of the first sensors t...

Looking forward to your post. Tom

Follow up on IR range detection While experimenting with the IR sensors I found something I though was strange. …. Here’s my breadboard setup. ...

Post Script If and when I do this over again I would add a bare wire loop that is big enough for an alligator clip and connect it to the battery g...

@robotbuilder I like that overlay! I’m forever reaching for the Pico pinout chart. I have a surprising amount of Arduino code that I’ve written a...

and @inq Where this conversation is going reminded me of a Dead Reckoning Competition that I saw years ago. Check it out. I believe that the winne...

@robotbuilder Yeah, I like programming the Pico. Its seems very flexible and coding pins for PWM output is a breeze. More to the point it's only $...
