Hey, sorry, I disappeared for a while after this conversation. I did let my grandson play with the little robot, and he liked it a lot. Later I revi...

Good, thanks. That answers my question - the S3 is a newer version than the ones that I have. So I can use these or spend a few bucks for the newer ...

Thank you again for your always valuable advice. I think your first sentence provides your top recommendation, and if I want to play with this with m...

Is the ESP32-S3 the same ESP32 that I see all over Amazon? Has it changed at all over the past few years? I have a couple of ESP32 boards that I bou...

I didn't get time to really look at your video until this evening, and, yes, it's very responsive. I know nothing at all about web-sockets, but lack ...

@zander That sounds workable and interesting. Keep us posted when you get into the project. Don't use the Uno R4, though. It has a completely diffe...

That all sounds like fun to me. 😀 Is there a forum here for this kind of conversation? I love the feeling of watching my code come to life, especial...

@inq I probably could have if I'd been here at the time, but it's no longer an option. Still, the SKU (ASIN, in Amazon's terms) is a definite identif...

Are you suggesting that the robot could use two regular wheels and two Mecanum wheels, where the undriven Mecanum wheels would be used like the traini...

That's a great idea! I think my phone is capable of that kind of video. I'll look into it. My gut feeling (based mostly on experience with other ch...
