Arduino 2.1.1 (on computer Beelink) with compile error message: "Compilation error: WebSocketsServer.h: No such file or directory " For the fifth error message, you need to download the WebSocketServer library: https://github.com/Links2004/arduinoWebSockets/ The version of Arduino IDE should not change the way the code is compiled. I meant the ESP32 library's version should be 2.0.12, not the version of Arduino IDE. Please let me know if you have difficulty finding this section in the doc center: https://docs.petoi.com/arduino-ide/upload-sketch-for-biboard#id-2.1-prepare-the-esp32-development-environment Could you tell me the link path you used to find any of the docs, so we can improve the link logics.

When you install ESP32 library, did you use version 2.0.12?

What a unique pet! How smart is it compared with dogs and cats? Does it smell? I have a mantis.

For OpenCatEsp32, you need to select the board as ESP32. However, in your screenshot, you selected Arduino Uno.

I can see it's doing cheers and boxing😂

I'm impressed how fast you can adapt and fix the problems. As we are working on the standard PCB, I also like to see how people build the circuit like my old days. I wonder if you would like to write a post on how you make this DIY version working and publish it on Hackster.io. We can send you a standard controller (NyBoard/BiBoard) as a gift.

The onboard EEPROM only has 1000 Byes. Without an I2C_EEPROM, you can not save too many instintct' data. Try to use the InstinctBittleShortExample.h.

The calibration constants are saved in the on-board EEPROM. You also need to wire an 64kb I2C EEPROM.

What controller board are you using? A DIY version or our BiBoard/NyBoard?

Hi, could you send a video to support@petoi.com so we can better diagnose the problem?

Hi, Sorry I missed your post. Please write to support@petoi.com and I will send you a calendar link for a remote session to debug.

Hi, Do you use Arduino IDE or the desktop to program the robot? Could you confirm the version date of the firmware running on the robot? You can check the "About" of the desktop app, or enter '?' in the serial monitor of the Arduino IDE.

Wow! A master piece. I'm so excited to see this mod!!!

Andres, if you are using the ESP32Servo installed via the library manager, you need to go into that library file and modify a few lines:

Hi, good catch! Pin 9 and 10 can be used either as I2C or UART. But at the same time, in a function set, their role is fixed. The modules are not activated simultaneously. More specifically, Serial2 is typically used by a master device, such as the Raspberry Pi. If a camera is needed, it's usually attached to the Pi rather than connected to the I2C port of the BiBoard. In the module manager, there's a logic check for the case when both modules are competing for the same port. The previous logic was to make all the modules exclusive. i.e., only one module can be active, and it will turn off the other modules. In a later revision, we excluded the voice and the backtouch sensor from the rule. However, the camera will still force Serial2 to turn off. void reconfigureTheActiveModule(char *moduleCode) {   if (moduleCode[0] == '?') {     showModuleStatus();     return;   }   bool statusChangedQ = false;   // PTHL("mode", moduleCode); // negative number will deactivate all the modules   for (byte i = 0; i < sizeof(moduleList) / sizeof(char); i++) {                                               // disable unneeded modules     if (moduleActivatedQ[i] && moduleList[i] != moduleCode[0]) {                                               // if the modules is active and different from the new module       if ((moduleList[i] == EXTENSION_VOICE || moduleList[i] == EXTENSION_BACKTOUCH) && moduleCode[0] != '~')  // it won't disable the voice and backtouch         continue;       PTHL("- disable", moduleNames[i]);       stopModule(moduleList[i]);       moduleActivatedQ[i] = false;       statusChangedQ = true; #ifdef I2C_EEPROM_ADDRESS       i2c_eeprom_write_byte(EEPROM_MODULE_ENABLED_LIST + i, false); #endif     }   } #ifndef I2C_EEPROM_ADDRESS   config.putBytes("moduleState", moduleActivatedQ, sizeof(moduleList) / sizeof(char)); #endif   for (byte i = 0; i < sizeof(moduleList) / sizeof(char); i++) {     if (moduleList[i] == moduleCode[0] && !moduleActivatedQ[i]) {       PTHL("+ enable", moduleNames[i]);       initModule(moduleList[i]);       statusChangedQ = true;     }   }   if (statusChangedQ)  // if the status of the modules has changed, show the new status     showModuleStatus(); }

Congratulations!

Yes, you're right. The legs appear to be installed when they were in rest mode.

Hi, could you post some pictures or a short video to show the boot up movements? Those visual details will be extremely helpful to debug the problem.

Hi, you can test the example code for https://github.com/mu-opensource/MuVisionSensor3's card demos using the Arduino IDE. After installing the library, you can find the examples in Arduino->File->Examples->Mu Vision Sensor 3.
