1. A mobile robot having a removable wheel-drive assembly, comprising:
a mobile base having a chassis and a first wheel well member including a flange;
a removable wheel drive assembly, including:
a mounting bracket configured to be removably connected to the chassis of the mobile robot proximate the first wheel well member;
a motor drive unit disposed on the mounting bracket;
a wheel connected to the motor drive unit via an axle; the wheel having a tire disposed thereon; and
a second wheel well member disposed on the mounting bracket and positioned between the motor drive unit and the wheel, the second wheel well member including a central section having an aperture through which the axle passes and a top surface;
wherein the top surface of the central section of the second wheel well member engages with the flange of the first wheel well member of the mobile base when the removable wheel drive assembly is mounted on the mobile base;
wherein the second wheel well member includes a first side section extending in a first direction from the central section and a second side section extending in a second direction from the central section, wherein the second direction is opposite the first direction; and
wherein the second wheel well member includes a first curved fender extending outwardly from a face of the first side section and positioned proximate a tread surface of the tire; wherein the first curved fender is conformed with a curve of the tread surface of the tire; and wherein the second wheel well member includes a second curved fender extending outwardly from a face of the second side section and positioned proximate the tread surface of the tire; wherein the second curved fender is conformed with the curve of the tread surface of the tire.
