X and Y with Raspberry Pi

[gproduct]

Basiclly my question is how can I make a robot and works on x and y coordinates.
When I want it to go on x=50 and y=50 then it goes there.
Is this possible with the raspberry pi and python

Yes, it's perfectly possible.

I'd recommend a robot platform with stepper motors to drive the wheels. That's the easiest way.

You could also use DC motors with an optical encoder on the output.

Yea but I'm more interested in the code

Pseudocode

Input x
Input y

Point front of robot forwards

Advance y steps

If x > 0
. Turn right 90 (LH motor fd RH motor rev)
. Advance x steps
Else
. Turn left 90
. x = x * -1
. Advance x steps
