The long weekend was a busy one with lots of progress made on the mini sumo. I sat down in front of the mill, and machined the robot’s body out of a single piece of 1″ thick Delrin, a task requiring a lot of care to not mess up, as one slip up has the potential to ruin the entire part, and hours of work.All in all, I think it turned out very well. Delrin machines very well, although does require a vacuum cleaner close by to continually clean up all the chips that accumulate, especially considering how much material I removed….

I also spun the two aluminum motor mounts, and cut the stainless steel base plate that seal off the bottom of the body. Still a lot of work to do on the chassis, and the circuit design is progressing slowly.. Now it’s just a race against time to get the PCBs made, circuits debugged, and a rudimentary program written up to get the robot running for the games. It’ll be tight, but I think It will be ready…

Here are some additional pictures…
