- Replace wifi.cpp/wifi.h with wifi_manager.cpp/wifi_manager.h: AP and STA run together, external WiFi credentials are stored in NVS and editable at /wifi, with optional static IP, 15s auto-reconnect, disconnect reason reporting, and build/version diagnostics - Fix MPU6050 I2C port to I2C0 to match the board wiring - Initialize distance_zeropoint at startup and on Robot Go! rising edge - Clamp angle_zeropoint to +/-10 degrees to prevent balance-point drift - Add DEBUG_DISABLE_YAW switch and periodic balance debug output - Update WiFi setup instructions in README.md and README_CN.md

Mechanical Structure Documentation
- The file "OriginalRobotModel.stp" is the robot model file.
- The "Parts-Manufactured" folder contains parts that need to be processed and produced by yourself, including 3D printing, CNC, and panel cutting.
- The "Parts-Purchased" folder contains parts that need to be purchased.
PCB Documentation
- There are four PCBs that need to be fabricated; the circuit boards provide both the schematic and PCB source files, and the IDE used is LCEDA.
- The main control board is based on the ESP32, with the brushless motor driver chip being the L6234PD013TR.
- The encoder chip used is the AS5600, communicating with the main control board via the I2C interface.
- The IMU used is the MPU6050 module, which shares the same I2C interface with the right-side encoder.
- The servo debugging board unifies the two serial lines into one signal line, completing the task through time-division multiplexing to send and receive data.
- In addition, you will need three GH1.25 4PIN double-ended cables, with a recommended length of 15cm. These need to be purchased separately.

Source Code Usage
- Based on Arduino IDE, it is very easy to learn and use.
- The brushless motor drive for the wheels is based on simpleFOC.
- The left bus servo ID is 1, and the right is 2; the calibration for the legs to fully squat to the mechanical limit position is 2048; configuration is done using FEETECH Debug Software.
- The ESP32 itself has WiFi capabilities, with the webpage code stored in flash, transmitting JSON data via the WebSocket communication protocol.
- Please use the WebSocket library located in 3.Software/libraries. The recommended esp32 version is 2.0.3.
- There are two WiFi models, AP mode and STA mode. AP mode uses the device as a wireless hotspot, and STA mode uses the device as a client to connect to an existing wireless network.
Usage Instructions
-
- Connect the battery's XH2.54 plug to the rear interface of the main control board and turn on the switch to power the robot.
-
- After turning on the switch, a red light on the main board will indicate that the power is on.
-
- Next, the wheels will start FOC motor initialization, with the wheels moving slightly and the legs starting to move.
-
- If the battery is sufficient, the blue LED on the main control board will light up. If it does not light up, charging is needed.
-
- After this process is complete, press the EN button on the main control board to restart. Connect to the robot's WiFi network
WLROBOT(password12345678).

- To use an external WiFi router, open "WiFi 设置 / WiFi Settings" on the page, enter the 2.4 GHz SSID/password (static IP is optional), and save. The robot will reboot and join that network. The
WLROBOTAP remains available as a fallback.
