AndyB: We got one similar to the one you linked at a Home Depot when we went to the Championships in Atlanta a couple of years ago. Found it 10 minutes before the store was shut,
and the lights were being shut off
. Otherwise we'd of had to carry the robot from pit to field.
It's a very good robot cart base, 28" wide x 48" length, and good tires for the bumps, and the HD version had removable sides to prop the robot up a little higher. We end up bringing our "art cart" cart instead which - every year - the robot doesn't
quite sit on properly.
I'm trying to get the manufacturing crew to build on the HD cart a scissors lift and battery/tool shelves under (even drew up some ideas for them), but they are very slow to start on it. Maybe a couple days before we go to our first regional next year?
