I can't really comment about the drivetrain, other than the fact that I really like it, and that student designer Ryan Tam (Gr. 11) deserves a tons of recognition for the design and manufacture of it. He worked under the mentorship of Mr. Stehlik, and there are a lot of neat little details in it that just don't show up in this picture... (i.e. all 4 side plates are identical, how the square channels are securely connected to the side plates with only one fastener, the in-between CIM "floating" encoders + mounts)

It's not flashy, but it's really well thought out, with a ton of detail to maximize ease of machining, assembly, and maintenance.

To answer some questions:

Yes, the smiley is covering something. We noticed one of the frisbee manipulating components got into the picture, and needed to be covered up.

The air tank holder is custom cut 1/4" lexan on our CNC router, again designed by Ryan Tam. It is basically four holes, as the tanks have a nice raised boss at each end that you can support them by.

As for CAN, it worked well for us last year, but we had a few hundred lines of code dedicated to CAN Error Recovery. Without it, we would have been dead in the water. We used the black serial adapter last year, and this is the first year we are using the 2CAN. It's still a bit early to give any meaningful feedback, as all we've done is some light open-loop driving.

Im interested in the CAN Error Recovery stuff. Could you elaborate?
