Ok but one thing – Sphero Edu Review

I have a Sphero mini and I wanted to make a program to get it through an obstacle course. Unfortunately, my code was inaccurate with the actual robot. I could program it to go straight, but it would go 45 degrees to the right every time. Not sure if it's the robot or the app, but it was quite irritating for a little bit.
