Abstract

The present disclosure provides various advancements for mobile and automated processing utilizing additive manufacturing. The present disclosure includes methods for the utilization of mobile and automated processing apparatus and may include examples of sealcoating operations. In some examples, omnidirectional drive systems such as Mecanum wheels may create novel operational aspects. Artificial intelligence techniques may enhance operations and may be used to create model for the processing apparatus.

First claim

What is claimed is:

1. A mobile additive manufacturing apparatus comprising:
an omnidirectional drive system operative to move the apparatus along a surface, wherein the omnidirectional drive system employs at least a first omnidirectional wheel directly attached to a first motor, and wherein the first motor has operational modes to be engaged in a forward moving, reverse moving or stationary configuration,
a navigation system to determine location;
a controller capable of executing algorithms and providing control signals,
a vision system capable of scanning the surface and measuring a topography of the surface;
an additive manufacturing system to deposit at least a first material in a prescribed location on the surface according to a digital model processed by the controller wherein the additive manufacturing system deposits material while the omnidirectional drive system changes a direction of movement of the mobile additive manufacturing apparatus using a change in an operational mode of at least the first omnidirectional wheel; and
a power system capable of providing power to operate at least the drive system, navigation system, controller and additive manufacturing system;
an artificial intelligence processing system, wherein the artificial intelligence processing system is one of a separate system from the controller or a sub-system of the controller; and
wherein the artificial intelligence processing system comprises an artificial intelligence chip and; wherein the artificial intelligence chip has been customized to interface with the vision system, the omnidirectional drive system, and the additive manufacturing system.

2. The apparatus of claim 1 wherein the artificial intelligence chip has been further customized to interface with the controller, wherein the controller is a separate system from the apparatus.

3. A method of depositing a material on a surface, the method comprising:
obtaining a mobile additive manufacturing apparatus comprising:
an omnidirectional drive system operative to move the apparatus along a surface, wherein the omnidirectional drive system employs at least a first omnidirectional wheel directly attached to a first motor, and wherein the first motor has operational modes to be engaged in a forward moving, reverse moving or stationary configuration,
a navigation system to determine location,
a controller capable of executing algorithms and providing control signals,
a vision system capable of scanning the surface and measuring a topography of the surface,
an additive manufacturing system to deposit at least a first material in a prescribed location on the surface according to a first digital model processed by the controller wherein the additive manufacturing system deposits material while the omnidirectional drive system changes a direction of movement of the mobile additive manufacturing apparatus using a change in an operational mode of at least the first omnidirectional wheel,
a power system capable of providing power to operate at least the drive system, navigation system, controller and additive manufacturing system;

orienting the mobile additive manufacturing apparatus upon the surface, wherein the orienting comprises engaging at least the first omnidirectional wheel directly attached to the first motor into one of a forward moving or reverse moving configuration;
scanning a portion of the surface beneath the mobile additive manufacturing apparatus with the vision system;
creating the first digital model, wherein the first digital model is optimized for path planning for movement with the omnidirectional drive system and operation of the additive manufacturing system;
initiating processing with the additive manufacturing system according to the first digital model, and simultaneously engaging at least the first omnidirectional wheel directly attached to the first motor into one of a forward moving or reverse moving configuration according to the first digital model, wherein the mobile additive manufacturing apparatus changes a direction of motion without rotating the first omnidirectional wheel; and
scanning a second portion of the surface beneath the mobile additive manufacturing apparatus with the vision system after a movement of the mobile additive manufacturing apparatus.

4. The method of claim 3 wherein the additive manufacturing system deposits a seal coating material.

5. The method of claim 4 wherein the additive manufacturing system deposits the seal coating material with one or both of: a spray system and a drip system.

6. The method of claim 5 wherein the additive manufacturing system deposits the seal coating material wherein the one or more of a spray system or drip system components are attached to a rotational gantry, wherein a rotational orientation is set according to the first digital model.

7. The method of claim 6 wherein the additive manufacturing system additionally comprises a flexible blade, wherein the flexible blade scrapes material upon the surface.

8. The method of claim 4 wherein the first digital model is based upon a model of at least one of: a roadway, a driveway, and a parking lot.

9. The method of claim 8 wherein the first digital model includes a path plan where the omnidirectional drive system is used to create a continuous movement flow of the mobile additive manufacturing apparatus during operation of the additive manufacturing system wherein wheels of the omnidirectional drive system do not pass over portions of the surface that have been processed with the additive manufacturing system.
