And by the time the fleet spins up to 25 robots on March 1, it’ll be the largest swarm of Tug medical automatons in the world, with each robot traveling an admirable average of 12 miles a day.

It has a thinner front and a bed in back, which people roll big cabinets onto. The second is more like a van, boxier with built-in cabinets. This is the drug-pusher.
