AttachNeoteric writes “This is my second robot after getting the kit for Christmas. No prior electronics experience. The robomaid redo I have been working on is complete. I call it Robomaid2. It uses the outside of this product. It uses 5 IR pairs. 2 in front, 2 on the side, one in back. The front pair is for detecting mfront collisions. The theory of the side pair is that the robomaid2 can hang very close to the walls and cupboard bases, where most of the dust is. (I have not completed the code for this, although it works pretty well like it is) The back IR helps when the robot gets a little too cramped. It rotates, and the back IR helps it get out of loops by kicking the robot forward.” [via] Link.
