ASSEMBLY .
The assembly is pretty much done !!! We just have to take care of the wiring before being able to bolt the servo horns in their final position .
WIRING .
software (and servos setup) .
We will now see how to use the software and setup the servos .
The software comes in 2 version :
- An executable that you just have to download and run (this is great if you can't code . unfortunately this only works on windows) .
- And a repository including all the python, UI and haar cascade file required to run the program . Feel free to improve and build upon the existing code !
