Nothing really. What I'm talking about is a block of aluminum with a hole drilled partway though (like halfway maybe) so it can hold an aluminum shaft as a dead axle. Then, the block is mounted to the robot with bolts and its height can be adjusted with shims. Not really a pillow block in the traditional sense, but similar.

is live-axle a more economical choice?

Generally no. A bolt through a hole in the frame can serve as a dead axle, with live you need keyed/hex/spline/etc shafts, bearings, pillow blocks, so on.

Usually yes. If you used gears for power transmission, you'd connect those to your shaft.
