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.
- 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.
- ...

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,
and installed in my robot. You can also add the OLED and MPU6050 via the I2C bus, and connect a touch sensor to GPIO-13.
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!
