Hello,

My name is Phillip. I am interested in building small, light-weight AUTONOMOUS , wifi-enabled robots.  These robots should cruise around the living room in an intelligent manner.

"Autonomous" for the most part is to have all navigation, sensors, intelligence , etc onboard. It is tempting to use the wifi to send sensor data to a Mac or other computer. But I am trying to avoid that. Maybe it is ok to brain-dump via wifi to storage or converse with other bots.

These kind of goals preclude using Arduino type boards. They don't have neither the communication capabilities nor the computational power. 

Oh yeah, one more thing, I distrust anything with a heat sink or that uses floating point.

Best regards from a snowy morning,

Phillip

Looks like a job for at least ESP32

I just posted a comment in another thread about the Arduino Due board, and why people are not using it.  Are you saying that board does not have enough computational power?

Yes. I would like to use the ESP32 for wifi at first. Do all the heavy computational lifting and tweaking on my Mac, then move it all back down onto the ESP32....Maybe

I cannot find your comment about the Arduino Due. However , just looking at the specs, it has a much slower clock, less ram and no wifi.

Indeed, spec wise, it's not as high as the ESP32, as I thought you weren't too worried about the WiFi, but such specs alone do not necessarily make it as slow as you might think, and it's a pretty good all round micro controller, certainly the best Arduino available!

If you really want a fast micro controller, then have a look at the Teensy 4.0, which will completely blow away the ESP32, by miles!

Hi !

Wow! Thanks for pointing me towards the Teensy 4.0

I  looked at the specs on the Teensy 4.0 and was impressed enough to buy one.

Thank you for the tip.

You're welcome!
I am also waiting to get a couple of these little powerhouses! 🙂
