ESP8266 project for Alpha 1S robot control.

RobotControl

Arduino ESP8266 project for UBTech Alpha 1S Controller.

Initial version 1.0 comes from the sample in my UBTech library.

Versionn 2.0 will define a new set of communization protocol. In this version, it will support both V1 & V2 commands.

Major changes in V2, V2.2, V2.3

• New V2.0 communication protocol to avoid misinterpretation (some V1 commands are kept for bluetooth control)
• Support control from USB, Bluetooth and Wifi (connect to router or AP mode)
• Action setup by reading position from robot
• Convert action from UBT action file in aesx and hts format
• Play MP3 with action
• Use MPU 6050 to detect current situation
• Define the action to stand up after fall down for both face up & face down cases
• Touch sensor and response for single, double and triple click, and long touch.
• Define events via Blockly UI in MyAlphaRobot v2.2+
• Add Sub-System Bus for other device, e.g. Ultrasonic, PSX Control
• Add USB-TTL mode to work as testing board for serial servos.
• Option to set action speed
• ......

Dependency

• OLED12864 library

Already included in lib_deps.

Installation

This is a Visual Studio Code project with PlatformIO IDE.

• Install Visual Studio Code
• Install the PlatformIO IDE extension
• Open the folder in Visual Studio Code

Hardware

• ESP8266 board
• HC-05 Bluetooth module (optional)
• MP3-TF-16P MP3 player (optional)

Pin Assignment for ESP8266 Board

Pin	Usage
GPIO-2	Connect to Rx of serial console for debug output
GPIO-4	Connect to SDA of I2C bus
GPIO-5	Connect to SCL of I2C bus
GPIO-12	Connect to signal pin of Servo
GPIO-13	Connect to Touch sensor
GPIO-14	Connect to Sub-System Bus (for PSX Control, Ultrasonic, ...)
GPIO-15	Connect to head led
GPIO-16	Connect to Rx of MP3 module
Rx	Connect to Tx of HC-05
Tx	Connect to Rx of HC-05
I2C	for MPU6050 and OLED display

The PC setup program MyAlphaRobot can be found in https://github.com/Super169/MyAlphaRobotV2/releases/tag/MyAlphaRobot_2.3

The new version support event setting by Blockly UI.

And also online update firmware up to 921600bps, it takes less than 10 seconds to flash the firmware.

You need a ESP8266 control board in order to use this firmware.

You can make a simple PCB like this,

I just make one as below, I have removed the HC-05 as it can already controlled by smartphone via WiFi.

and this is my testing environment for program development, including PSX Control and Ultrasonic Sensor.

Or if you cannot make the PCB yourself, you can buy a ready to use control board from Taobo. https://item.taobao.com/item.htm?id=571368655206

ENJOY!
