Thank you!!😃

[@MiguelAngel-vg2dg]

It's great, I have a 3d printer, the other prices are for electronic components?

[@tangwoonthai]

Yes

[@daylenhigman8680]

Have you tried a CG based walking agorithom? Then you might be able to walk in any direction fluently! However it probably wouldn't to walk on slopes without full ankle flexibility

[@tangwoonthai]

When I google CG agorithom, all I got is 😕?😨?😰?😵???

[@daylenhigman8680]

@@tangwoonthai 🤣 I'll look more into it

[@hgaming2459]

For the two Potentiometers, how much Resistance (k) is recommended?

[@tangwoonthai]

I'm using 20k.

[@vladodm6161]

Hi, what kind of resistor are you using with GND to point 15 on the ESP32 (Robot controller) board.
Thank you in advance.

[@tangwoonthai]

1k ±-5%,according to the colour line .I actually just grab one resistor from my arduino kit without consider too much.

[@vladodm6161]

OK, thank you I'll give a 1k resistor.
Your project is very good, I'm just starting to build it.
Regards Vlado.

@@vladodm6161 , you're welcome.

@@tangwoonthai Please help, the robot controller has a properly programmed LCD works but I can't program the robot receiver, arduino still reports an error, Servo_ESP32.h: There is no such file or directory.
I also tried other versions of arduino, it still doesn't work (1.8.9,1.8.12,1.8.13)
Thank you in advance for your help.

​@@vladodm6161 , try to download some basic esp32 servo test code and see if it work.
