Abstract

Systems, methods and devices for the remote control of a robot which incorporates interchangeable tool heads. Although applicable to many different industries, the core structure of the system includes a robot with a tool head interface for mechanically, electrically and operatively interconnecting a plurality of interchangeable tool heads to perform various work functions. The robot and tool head may include several levels of digital feedback (local, remote and wide area) depending on the application. The systems include a single umbilical cord to send power, air, and communications signals between the robot and a remote computer. Additionally, all communication (including video) is preferably sent in a digital format. Finally, a GUI running on the remote computer automatically queries and identifies all of the various devices on the network and automatically configures its user options to parallel the installed devices. Systems according to the preferred embodiments find particular application in the pipeline arts. For example, interchangeable tool heads may be designed to facilitate inspection, debris clearing, cleaning, relining, lateral cutting after relining, mapping, and various other common pipeline-related tasks.

Claims

1. A method of performing rehabilitation on a pipeline, the pipeline including a main pipe and at least one feature of interest in the main pipe, the method comprising:

identifying, using a robotic device, the at least one feature of interest in the main pipe;

implanting, using the robotic device, at least one marking device into a wall of the main pipe proximate the at least one feature of interest; and

sensing, using the robotic device, the at least one marking device from within the main pipe, wherein the at least one feature of interest comprises at least one of the following;

a crack in the main pipe;

a joint of the main pipe; and

a lateral pipe connected to the main pipe.

2. The method of claim 1, wherein identifying the at least one feature of interest comprises using the robotic device to perform a video survey of the pipeline.

3. The method of claim 1, wherein identifying the at least one feature of interest comprises using the robotic device to perform range mapping of the pipeline.

4. The method of claim 1, wherein implanting the at least one marking device into the wall of the main pipe comprises implanting a plurality of marking devices into the wall of the main pipe proximate the at least one feature of interest.

5. The method of claim 1, wherein implanting the at least one marking device into the wall of the main pipe comprises using the robotic device to drill into the wall of the main pipe.

6. The method of claim 1, wherein sensing the at least one marking device comprises electromagnetically sensing the at least one marking device.

7. The method of claim 1, further comprising using the robotic device to clear debris in the main pipe.

8. The method of claim 1, further comprising using the robotic device to clean a surface of the main pipe.
