Not an issue, just telling

Why not use esp32 as microcontroller? It has more ram, 4MB flash memory and built in wifi Bluetooth... That will be great.

[jaiwiwjwjwisn]

Maybe we will also be able to ota update.

I found one but that's only shield and very outdated

We never found a proper servo library for esp32 they all act very strange, any recommendation @jaiwiwjwjwisn ?

Please send repo /link of servo I'm gonna check out. And if possible i will port Sir. 🙂

It's very painful to see a great project like otto can't use powerful microcontroller because of servo library.
I found https://github.com/pvanallen/VarSpeedPython and https://github.com/RoboticsBrno/ServoESP32 what are they lacking? Please let me know.

Bytheway rpi pico is also powerful and has 2MB flash (16MB in clones) and almost same size as arduino nano. Best part is it has a good servo Library, please checkout. And unleash true potential of otto 🥰.

Any thoughts @cparrapa ? https://github.com/guavuavcycayfayqvqu/OttoNinja/tree/devel/servo

Hi @guavuavcycayfayqvqu or jaiwiwjwjwisn

We would like to help you. Please see the information in the OttoDIYLib comment OttoDIY/OttoDIYLib#70

It is a pity indeed @guavuavcycayfayqvqu but once you test them in the hardware you will see what I meant, @sfranzyshen is doing a good work to have the compatibility and performance qual for nano and ESP boards.

There are many:
https://madhephaestus.github.io/ESP32Servo/annotated.html
https://github.com/jkb-git/ESP32Servo
https://github.com/RoboticsBrno/ServoESP32 we were also testing and it was giving some errors and abrupt movements

They need to be properly merged with the Otto DIY Lib in a ways that it keeps backwards compatibility.

I also forgot to mention hardware was limitation until the new https://hprobots.com/ kit came out that one is ESP32 based and has the perfect size for Otto.
