Problem with the Makeblock Smart Camera

Hey everyone!

We are a 3-person team from France doing the Robocup junior rescue line. We will be participating in the nationals and European competition in Varazdin, Croatia next month so we want our robot to be able to save the reflective balls (victims). We’re using an mBot 2 associated with the make block smart camera.

The camera CAN detect any coloured balls (orange and green that come in the box) but it can’t seem to be able to detect the presence of the reflective balls that we need to save.

We know that this is due to the fact that the ball reflects everything around them and so is not a single colour and we have tried flashing a red light at the ball but it still doesn’t seem to work.

Does anybody know how we can solve this issue?
Thank you in advance.


Maybe this information will be useful for you. A few years ago, my team noticed an interesting effect of IR rangefinders, that when the IR rangefinder was pointed at a reflective ball, its returned readings were maximum.

Good luck!
