Show off your machining!

We chose this mostly for footprint size. They are 6" by 6" square. They're pretty light as wel though. 7.5 lbs each.
A whole drive base, including fame but no electronics weighs 37 lbs.

All of the drive gearing is in the lower box chain to save space on top.
There's a picture of the frame as it was weighed.

Here was a little 2079 project from Luncay. Unfortunately the swerve drive wasn't as effective as we wanted it to be, but the machining is pretty cool.








Here's a link to more pics.

I have always thought a circular swerve would be cool. My next disign iteration has an octagonal pivot for space savings and strength.

Did you have trouble with your cim motor wires tangling?

Also, did you have a special tool and a 4 axis cnc mill to cut the sprockets?
