More CNC’d parts

I have been playing more with my CNC machine and am working on some tiny treads for the GM10 motors. Here is a pic of the drive sprockets that I made. That is 1/4″ square grid paper that they are sitting on. I cut some prototypes out of nylon (yuck) then cut these out of some sample scraps of “Butter-Board“. That stuff cuts nice!
I made a female mold for the treads, but I don’t like it, so I’m going to redesign it. Maybe the sprockets also. I just got a 1/16″ end mill in the mail today so I can probably make them better now anyway. As soon as I tram my mill and get out the backlash, since my circles appear slightly out of round.

Deskpet redux

As an ongoing project (see Flik previously) I have been working on a small robot that could live on my desk as a pet, hence the Deskpet moniker. I’ve done some research into how to give him personality, as well as how to add emotion (links soon). Last weekend I decided to play with my CNC mill and cut out a design for the body of my deskpet robot. I’ve been working on this design for a while so it was just a matter of loading and running the program. Then, one of the guys at work used the CNC’d master to make an RTV mold, and I molded a urethane copy:

The body is shown with a Nickel for scale. The pics are really crummy because I used my cell phone, I’ll post better pics later. This will make a robot small enough to use for Micro-Sumo competition, and is designed around the GM-10 motors. I may end up selling these as just the body, or as a complete robot kit.
