I set up the Adafruit Huzzah32 Feather Board with the FS90R continuous rotation servos (powered by an external power bank), the Adafruit NeoPixel FeatherWing, and the Adafruit 9-DOF Absolute Orientation IMU Fusion Breakout. In addition, I got the Roco library working locally on my computer and wil...

The code had estimated the position of the ball quite well for the hi-def images but not so for the 800x600 images:...
