Dear Community 
Let me introduce my project which can help people to interact with the keyboard by voice or through pre-prepared scripts or react to images from the screen (monitor).
Please keep in mind at the beginning that this is a commercial project looking for fundraising on Kikstarter or Indiegogo, not open source until the end of the fundraising campaign 
Also I apologize if my English looks strange. I hope this doesn't hide the idea 
The idea is to create RoBoArm as much affordable as possible. Unfortunately I can’t provide a better price for such things like Arduino (tested on UNO and Nano), PCA9685 16 servo motors board, wires, bearings or filament for 3d printer. So I would like to give an opportunity to find those things on Aliexpress, Amazon or any other local markets to interested people. It will significantly speed up process of making RoBoArm and reduce price.
I created 3d STL files of RoboArm components.
And developed Windows application to control RoboArm
To assamble RoboArm you need to 3d print details,
to buy 4 MG90-S servo motors
to buy 1 bearing 35x47x7-mm d = 35 D = 47 B = 7
You have to buy Arduino, PCA9685 16 servo motors board and required wires
And have 1 USB 2.0 power adapter 5V 1-2A to power supply PCA9685 16 servo motors board
UpLoad modified ino file into Arduino (tested on Uno and Nano)
Assemble and connect
Download and register Windows 10-11 application
Windows 10-11 application
As a result you will get a pretty smart key clicker. One of the examples how to use RoboArm and small promo.
I apologize for such brief presentation. But I have forum's warning
