The welcome robot uses U+ PROGRAM CARD as the main control board. Compared with traditional development boards, U+ PROGRAM CARD adopts plug-in installation, which is easy to disassemble and assemble, and has strong scalability.


The welcome robot is equipped with the U+A5 MINI expansion board and sensor kit developed by Hello STEM, making the project easier to build, with more straightforward assembly and wiring and more stable performance!

Function:
We provide 2 open source program codes that can achieve the following functions.
Welcome robot: When the ultrasonic module senses the human body or object, the welcome robot will make a welcoming gesture and make a sound.
Singing robot: When the ultrasonic module senses the human body or object, it will play Happy Birthday to you when the distance is less than 10cm, play Twinkle Twinkle when the distance is less than 30cm and greater than 10cm, play Two Tigers when the distance is less than 50cm and greater than 30cm When it exceeds 50cm, the current song will be played and then stopped.
You can also modify the sample program or write a new program by yourself through programming software such as Arduino IDE and Mixly to control the welcome robot.
