Looking for resources for Robotic Arm programming

So I have a couple of super simple 3 axis robotic arms. One is an ArmUno and the other is 3 DOF pick and place vaccume bot. I have been able to get manual controls working in python using a Raspberry Pi, but now I am looking for how to program it to go to a specific grid point and pick something and pit it at another grid point.

The problem I am running into is I don’t know how I should indicate the work area and then convert those grid points to degrees on the servos. If anyone has any resources on that it would be super helpful.
