Abstract

A modular inspection vehicle having at least first and second motion modules is provided. The first and second motion modules are connected to a chassis. The first motion module includes a first wheel mounted to the chassis. The second motion module includes second wheel mounted to the chassis, the second wheel being at an angle to the first wheel. The vehicle further includes a navigation module configured to collect position data related to the position of the vehicle, an inspection module configured to collect inspection data related to the vehicle's environment, and a communication module configured to transmit and receive data. The vehicle can also include a control module configured to receive the inspection data and associate the inspection data with received position data that corresponds to the inspection data collect at a corresponding position for transmission via the communication module.

First claim

The invention claimed is:

1. A modular inspection vehicle, comprising:
a chassis, wherein the chassis comprises first and second chassis sections, each of the first and second chassis sections are coupled to a respective one of a first wheel and a second wheel, the sections being connected via a linkage that permits a degree of freedom of movement between the first and second chassis sections and maintains the first and second wheels in contact with the surface on which the inspection vehicle is traveling;
a first motion module, the first motion module including:
the first wheel mounted to the first chassis section for rotation about a first axis, wherein the first wheel is a magnetic driving wheel;
the second motion module, the second motion module including:

a second wheel mounted to the second chassis section, the second wheel being arranged to rotate about a second axis that is nominally perpendicular to the first wheel for orthogonal rotation with respect to the rotation direction of the first wheel and wherein the second wheel is a magnetic omni-wheel that permits the vehicle to change direction;
an inspection module connected to the chassis configured to collect inspection data related to the vehicle's environment;
a communication module connected to the chassis configured to transmit and receive data;
at least one power module connected to the chassis configured to provide power to the vehicle and its modules; and
a control module connected to the chassis configured to receive the inspection data and wherein the control module is configured to prepare the inspection data for transmission via the communication module.

2. The modular inspection vehicle of claim 1 , further comprising a navigation module connected to the chassis and configured to collect position data related to the position of the vehicle.

3. The modular inspection vehicle of claim 2 , wherein the control module is configured to associate the inspection data with received position data that corresponds to the inspection data collected at a corresponding position, and wherein the control module is configured to prepare the associated data for transmission via the communication module.

4. The modular inspection vehicle of claim 1 , wherein the chassis comprises first and second chassis sections, each coupled to a respective one of the first and second wheels, the sections being connected via a linkage that permits a degree of freedom of movement between the first and second chassis sections.
