Abstract
A smart steering assembly for a modularly configurable paving operations system includes an end structure at either end of a modular framework. Each end structure has a front and rear adjustable leg with a steerable crawler connected to each leg. A control system can rotate one or more steerable crawlers via the smart steering assembly to drive, steer, or reconfigure the system in response to user input or data received from one or more sensors. Steerable crawlers may be articulated independently or in unison via smart steering cylinders or actuators incorporating onboard sensors connected to the control system. Adjustable legs may alternatively be mounted to the end structure via leg pivots.
