Autonomous grain cart dimensioned to fit behind header

An autonomous grain cart, comprising:

• a width less than or equal to a distance from an end of a header of an agricultural vehicle to a lateral side of the agricultural vehicle, wherein the end and the lateral side are on a same longitudinal side of a lateral centerline of the agricultural vehicle, wherein the autonomous grain cart is configured to receive grain from the agricultural vehicle;
• a controller, comprising a one or more processors and one or more memory devices;
• a drive system communicatively coupled to the controller, wherein the controller is configured to instruct the drive system to propel the autonomous grain cart;
• and
• a steering system communicatively coupled to the controller, wherein the controller is configured to instruct the steering system to steer the autonomous grain cart;
• a communication device configured to send signals to and receive signals with a second communication device to coordinate with another queued autonomous grain cart to move into the present position of the automous grain cart with respect to the agricultural vehicle when the controller determines the autonomous grain cart should be instructed to travel to an unload position.

A system for conveying agricultural product, comprising:

• an agricultural vehicle comprising a header configured to harvest agricultural product from a field;
• a first and second autonomous grain carts, each having a width less than or equal to a distance from an end of the header of the agricultural vehicle to a lateral side of the agricultural vehicle, wherein the end and the lateral side are on a same longitudinal side of a lateral centerline of the agricultural vehicle, wherein the first and second autonomous grain cart each comprise:
• a controller, comprising one or more processors and one or more memory devices;
• a drive system communicatively coupled to the controller, wherein the controller is configured to instruct the drive system to propel the respective autonomous grain cart;
• and
• a steering system communicatively coupled to the controller, wherein the controller is configured to instruct the steering system to steer the respective autonomous grain cart;
• and
• an agricultural product storage tank configured to store the agricultural product;
• wherein each autonomous grain cart of the first and second autonomous grain carts is configured to receive the agricultural product from the agricultural vehicle and deliver the agricultural product to the agricultural product storage tank, wherein the controller and steering system of the second autonomous grain cart is configured to control the second autonomous grain cart to follow the agricultural vehicle and queue while the first autonomous vehicle is in an unloading position.
