A dolly, a dolly towing system and a method of operating a dolly towing system. The dolly includes a wheeled platform with a coupled electric generator and an automated safety interlock assembly. The interlock assembly includes one or more sensors configured to wirelessly detect whether the dolly and tow motor are safely joined to one another. A controller can be powered by a battery or related onboard source of electric current while the dolly or system are stationary, as well as by the generator when the dolly or system are moving. Signals indicative of the joining that are acquired from the sensors can be received and processed by the controller such that suitable circuitry can convey the processed signal in such a way that the signal provides an audible or visual notice of an operational status of the dolly or system to an operator.

A smart trailer system coupled to a trailer of a vehicle includes a sensor configured to measure a parameter of the trailer, a sensor interface board electrically coupled to the sensor and configured to retrieve the measured parameter, and a master controller communicatively coupled to the sensor interface board via a data bus.

The present invention relates to a transport wagon consisting of a base frame, wherein the base frame comprises a rotatable bogie assembly on its front side for attachment to a powered tow or push truck and comprises one or more front steering wheels placed on the front side of the base frame and one or more rear steering wheels placed on the rear side of the base frame, wherein the one or more front steering wheels and the one or more rear steering wheels are coupled in such a way to the rotatable bogie assembly, that in operation the one or more front steering wheels rotate along with the rotatable bogie assembly and that the one or more rear steering wheels rotate in opposite direction with respect to the rotatable bogie assembly, wherein the base frame comprises at least one longitudinal beam to which a front cross beam, a rear cross beam and at least one intermediate cross beam are arranged with intermediate spaces, wherein at least one intermediate space is arranged for receiving goods, wherein an intermediate wheel suspension with two or more intermediate wheels is arranged under one or more of the intermediate cross beams. The present transport wagon provides a transport wagon that remains well steerable on uneven floors.

An autonomous transport robot for transporting a payload, the autonomous transport robot including a drive section assembly having at least one motor and a pair of drive wheels coupled to the motor, a frame configured to support a payload, a transfer arm connected to the frame and configured for the autonomous transfer of payload to and from the frame, and a suspension system movably connecting the drive section assembly and the frame allowing relative movement between the frame and the drive section assembly.
