The 'feet' are most likely powered by some sort of worm gear, which has the added bonus of not back-driving. Can't tell exactly what motor that is, maybe a 775?
I honestly have no clue how they are able to get discs up to the shooter from their pickup, though. From what I can tell, the 'core' of the robot is electronics and I couldn't see anything much going on in there. Although, 0:10 you can see what I think is a disc queued up, right in the middle of the robot. Also, from the shots of them shooting, it looks like there is some sort of 'bucket' holding the discs that gets raised up to the shooter.
Mini-CIM on the shooter wheel, which seems to be a curved design of unknown arc-length. I saw another motor (550?) in a gearbox sticking up behind that, probably helping feed in discs.
Their drive wheels are the same custom molded urethane they used last year. Pretty neat process, lets them make a whole lot of them and colour them the way they like. Pretty grippy too.
At 0:47 a wild Talon appears.

You can also see gold (anodized?) versaplanetary gearboxes for their indexer/feeder 550 and their human feeder roller motor. I'm very interested in how they stack from their ground pickup. The aerial shot shows an empty bucket style hopper but no details of how discs go in or come out. The bucket lowers for floor collection and raises up to shoot and human load. I can't tell if they are pushing in from the bottom or top. But they pull from the bottom of the stack it looks like.
It's just amazing 13+ actuations and I'm pretty sure I missed some.
Also Justin, after watching this video 10+ times this is one of your best yet. Great job.
