In March, I started to do some of the micromouse parts agin. For example, one of the wheels was not working well, so I had to replace it. There was friction between the wheel and the base of the micromouse. I cut the edges next to the wheels to prevent this friction and sand the edges on the other side. However, we broke the micromouse base when we accidentally cut off the first side and replaced it with a new base. Then the PCB was made. We tested it and built it on the micromouse.
