Abstract: Autonomous mobile robots for transporting carts are described. An example robotic cart transport system includes a cart for transport and a robotic transport. The robotic transport includes a transport cab and a load handler. The transport cab includes a drive system and a sensor array positioned over the transport cab. The load handler includes a load base supported by a directable caster wheel, a lift table positioned over the load base, a lift abutment anchor, and a lift drive. The robotic transport can autonomously position the load handler under a cart, and the lift drive can raise the lift table up and off of the top surface of the load base, to a lifted position seated against the lift abutment anchor. The lift table will contact and lift the cart in this motion, and the cart can be transported to a new location by the robotic transport.
