I built the Coretec 4WD robot with my son last week, using a Pi Zero W and Explorer pHat, and hooked it up (eventually) to a PS3 controller.
It was working great, racing round the smooth kitchen floor, until one of the wheels flew off. When I put them on, they clicked on as if they were secured, but now they all seem to slide on and off pretty easily, and I don’t think they’d stay on for long.
Has anyone else come across this, and found a good way to secure them?
