We are having a problem and could use your advice if you have a moment:

1. We have built all the mechanicals (as shown in the photo) and they work well.
2. We’ve calibrated the x and y axis as you suggest in your build file. The robot moves quickly and
3. We’ve set up the vision system using colorful foam and it is successfully tracking the puck and the mallet. We can see it tracking the puck and projecting the straight and bounce trajectories.
4. We transferred all the edits and calibrations to AHR.bat and have downloaded AHR.bat to the Arduino.

BUT when we connect the vision system, the Arduino does not respond at all. We don’t know whether the PC isn’t sending signal or the Arduino isn’t synching the vectors or what?

Any advice?

Hi David!
Glad you are enjoying the process! :-)

Yes, looks like the PC is not sending any command to the Brain Shield. Lets check this:
1) Is the Robot connected to the computer via WIFI (and using the correct password: 87654321 ?
2) Have you tried to make the "INITIAL MOVEMENT PATTERN"? (video at:
3) Could you attach a screen capture of the computer detecting the foams and the "detection parameters" for those foams?
