We Need a Cart

What kind of features would you want in a robot cart? Obviously it has
to hold the robot, preferably in a more stable fashion than last year.
Some possibilities:
-Tool Storage
-Some kind of tie-downs or clamps to hold the robot down
-Battery storage
-Height-we can either have it be low so it's more stable, or at a height
that we can use it as a table to work on the robot (we could also
investigate the possibility of a lift)

Of course there are many more features we can consider. (Including
showoff-y ones like paint jobs and ground effect lighting) Once we have
an idea of what we want out of it, I can draft a design to make it out
of Bosch rail and we can actually build this thing.
