Abstract

A method of manufacturing an autonomous cart is provided. The method includes determining a mission type for the autonomous cart and determining a power system for powering the autonomous cart based on the mission type. The method further includes determining a drive system suitable for converting a power delivered by the power system into motive power suitable for moving the autonomous cart based on the power system and the mission type. The method further includes installing the power system onto a chassis of the autonomous cart and installing the drive system onto the chassis of the autonomous cart, wherein the autonomous cart comprises a control system configured to drive the autonomous cart autonomously via the power system and the drive system.

First claim

The invention claimed is:

1. A method of manufacturing an autonomous cart, comprising:
determining a mission type for the autonomous cart;
determining a power system for powering the autonomous cart based on the mission type;
determining a drive system suitable for converting a power delivered by the power system into motive power suitable for moving the autonomous cart based on the power system and the mission type;
installing, in a field, the power system onto a chassis of the autonomous cart;
installing, in the field, the drive system onto the chassis of the autonomous cart, wherein the autonomous cart comprises a control system configured to drive the autonomous cart autonomously via the power system and the drive system; and
reconfiguring, in the field, the control system based on the power system installed and on the drive system installed.

2. The method of claim 1 , wherein determining the mission type comprises determining a torque, a speed, a number of operational hours, or a combination thereof, for the autonomous cart.

3. The method of claim 2 , comprising determining the torque, the speed, the number of operational hours, or the combination thereof, comprises determining the torque, the speed, the number of operational hours, or the combination thereof, based on an agricultural crop to be carried by the autonomous cart.

4. The method of claim 2 , comprising determining the torque, the speed, the number of operational hours, or the combination thereof, comprises determining the torque, the speed, the number of operational hours, or the combination thereof, based on an agricultural vehicle to be supported by the autonomous cart.

5. The method of claim 1 , wherein determining a power system for powering the autonomous cart based on the mission type comprises determining the power system based on an availability of an energy source, a cost of an energy source, or a combination thereof.

6. The method of claim 1 , wherein the power system comprises a battery, a compressed natural gas (CNG) fuel canister, a supercapacitor, a hydrostatic system, an electric generator, a combustion engine, or a combination thereof.

7. The method of claim 1 , wherein the drive system comprises an in-wheel electric motor, a non-in-wheel electric motor, a hydrostatic pump, a chain drive, a shaft drive, or a combination thereof.

8. The method of claim 1 , wherein the control system is configured to drive the autonomous cart to follow an agricultural vehicle to offload an agricultural product from the agricultural vehicle onto the cart during operations of the agricultural vehicle.

9. The method of claim 1 , comprising installing a container for collecting agricultural product on top of the chassis.

10. An autonomous cart, comprising:
a chassis,
a power system disposed on the chassis and configured to power the autonomous cart, wherein the power system is configured to be installed onto the chassis in a field;
a drive system disposed on the chassis and suitable for converting a power delivered by the power system into motive power suitable for moving the autonomous cart, wherein the drive system is configured to be installed onto the chassis in the field;
a controller, comprising a processor and a memory, wherein the controller is configured to be reconfigured in the field, after determining a specific mission type, based on the power system installed and on the drive system installed; 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, wherein the chassis is configured to support a specific mission type via the power system and the drive system.

11. The autonomous cart of claim 10 , wherein the chassis comprises a second power system and a second drive system, the second power system is configured to be installed onto the chassis in the field to support the specific mission type, the second drive system is configured to be installed onto the chassis in the field to support the specific mission type, and the controller is configured to be reconfigured in the field, after determining the specific mission type, based on the second power system installed and the second drive system installed.

12. The autonomous cart of claim 10 , wherein the power system comprises a battery, a compressed natural gas (CNG) fuel canister, a supercapacitor, a hydrostatic system, an electric generator, a combustion engine, or a combination thereof.

13. The autonomous cart of claim 10 , wherein the drive system comprises an in-wheel electric motor, a non-in-wheel electric motor, a hydrostatic pump, a chain drive, a shaft drive, or a combination thereof.

14. The autonomous cart of claim 10 , wherein the specific mission type comprises a desired torque, a desired speed, a desired number of operational hours, or a combination thereof, for the autonomous cart.

15. A system for continuously conveying agricultural product, comprising:
an agricultural vehicle comprising a header configured to harvest agricultural product from a field; and
at least one autonomous grain carts configured to receive the agricultural product from the agricultural vehicle, wherein the at least one autonomous grain cart comprises:
a chassis,
a power system disposed on the chassis and configured to power the autonomous cart, wherein the power system is configured to be installed onto the chassis in a field;
a drive system disposed on the chassis and suitable for converting a power delivered by the power system into motive power suitable for moving the autonomous cart, wherein the drive system is configured to be installed onto the chassis in the field;
a controller, comprising a processor and a memory; 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, the controller is configured to be reconfigured in the field, after determining a specific mission type, based on the power system installed and on the drive system installed, and the chassis is configured to support the specific mission type via the power system and the drive system.

16. The system of claim 15 , wherein the power system comprises a battery, a compressed natural gas (CNG) fuel canister, a supercapacitor, a hydrostatic system, an electric generator, a combustion engine, or a combination thereof.

17. The system of claim 15 , wherein the drive system comprises an in-wheel electric motor, a non-in-wheel electric motor, a hydrostatic pump, a chain drive, a shaft drive, or a combination thereof.

18. The system of claim 15 , wherein the specific mission type comprises a desired torque, a desired speed, a desired number of operational hours, or a combination thereof, for the autonomous cart.
