I have finally managed to finish Marlon the Lego Mindstorms robot’s ultrasound sensor array so that he can scan objects in front of him and build a profile of those distances, both horizontally and vertically. Here is the video explaining a bit more about how I have created the ultrasound sensor array. It seems my video editing skills are coming on as slowly as my code, so apologies in advance, you can always skip to the links!
