It is a reverse ingeneering project of uArm from ufactory.cc.
To build it you will need this BOM:
Laser cutted acrylic glass 3mm
Laser cutted acrylic glass 5mm
Servo MG995 - 3pcs
Metal plate for MG995 - 3pcs
Stadart 9g servo with metal gear - 2pcs
Bearing 55x30x13 - 1pcs
Bearing 8x3x3 - 10pcs
Arduino with some kind of shield
A lot of screws
I attached PCB for my Arduino-compatimble board. Also you will find some software examples to run in different modes. Mouse control program works great with MouseControl 1.0.5 app from uFactory (https://ufactory.cc/en/download-center/).
Also you will find in thing files completely assembled SketchUp-model. There you can see how it's assembled.

I am a hardware engineer. It is my work and my hobby!
