Abstract

An apparatus for detecting objects on or beneath a surface of a medium having a reach-in arm, the base of the reach in arm connected to a platform, and the distal end of the reach-in arm connected to a sensor. The sensor detects objects on or beneath the surface of a medium and is capable of monitoring the distance of the sensor from objects in the path of the sensor. Motor controllers are connected to the reach-in arm and the sensor for controlling the movements of the reach-in arm and sensor. A computer is in communication with the reach-in arm, the sensor, and the motor controllers. The computer detects objects on or beneath the surface of a medium; determines the location of the reach-in arm and sensor relative to objects in their paths; and controls the movement of the reach-in arm and sensor either automatically using pre-programmed software or according to user inputted commands.

Claims

1. An apparatus for detecting objects on or beneath a surface of a medium comprising:

(a) a platform comprising a vehicle;

(b) a reach-in arm configured as a single arm having a base;

wherein the base of said reach-in arm is mounted to said platform;

(c) a ground penetrating radar sensor for sensing objects on or beneath a surface of a medium, wherein said sensor is connected to the distal end of said reach-in arm by a quick connect-interface configured to provide an automatic disconnect of the sensor from the reach-in arm, said quick-connect interface comprising a contact switch breakaway system and a spring mechanism;

(d) at least one motor controller electronically connected to said reach-in arm and to said sensor;

said at least one motor controller for controlling the movements of said reach-in arm and said sensor;

(e) a computer in communication with said reach-in arm, said sensor, and said at least one motor controller;

said computer;

(i) for processing data received from said sensor to detect objects on or beneath a surface of a medium;

(ii) for controlling the movement of said reach-in arm; and

(iii) for controlling the movement of said sensor.

2. The apparatus of claim 1 wherein the base of said reach-in arm is mounted to and extends outwardly from a front end of the platform.

3. The apparatus of claim 1 wherein said reach-in arm comprises a telescopic arm.

4. The apparatus of claim 1 wherein said reach-in arm comprises an articulating arm.

5. The apparatus of claim 1 wherein said reach-in arm comprises a conveyer system.

6. The apparatus of claim 1 wherein said reach-in arm comprises a plurality of segments;

each segment connected to a second segment by a joint;

said joint providing said computer with distance data used by said computer to control the direction of said reach-in arm and said sensor.

7. The apparatus of claim 1 wherein said reach-in arm is connected to said sensor by a quick connect-interface;

said quick-connect interface comprising a contact switch breakaway system and a spring mechanism.

8. The apparatus of claim 1 wherein said sensor and said reach-in arm are configured to search horizontal media and vertical media.

9. The apparatus of claim 1 wherein said reach-in arm is constructed and arranged to extend the sensor into hazardous areas while the platform remains in a safe area.

10. The apparatus of claim 1 wherein said computer is connected wirelessly.

11. The apparatus of claim 1 further comprising a second reach-in arm coupled to said platform;

wherein the base of said second reach-in arm is mounted to said platform, said second reach-in arm for physically inspecting a medium or an area surrounding a medium.

12. The apparatus of claim 1 further comprising a second sensor for monitoring the distance of said ground penetrating radar sensor from an object in the path of said ground penetrating radar sensor;

said second sensor coupled to said ground penetrating radar sensor and in communication with said computer;

said computer for processing data received from said second sensor to determine the distance between said ground penetrating radar sensor and objects in the path of said ground penetrating radar sensor.

13. The apparatus of claim 1 further comprising a marking system connected to said reach-in arm for marking surface of a medium where an object is located;

said marking system in communication with said computer for controlling said marking system.

14. The apparatus of claim 1 further comprising a display device in communication with said computer;

said display device for displaying data provided by said computer.

15. The apparatus of claim 1 further comprising a camera for capturing images of an area explored by said sensor, wherein said camera is mounted onto the distal end of said reach in arm.

16. The apparatus of claim 15 wherein the camera is capable of night-vision.

17. The apparatus of claim 1 further comprising an input device in communication with said computer;

said input device for transmitting instructions to said computer for controlling the movement of said reach-in arm and said sensor;

said input device providing instructions to said computer for controlling and moving said reach-in arm and said sensor.

18. A method for detecting objects on or beneath a surface of a medium, the method comprising:

(a) providing a platform comprising a vehicle and a reach-in arm configured as a single arm having a base that is mounted to said platform;

(b) providing a ground penetrating radar sensor for detecting an object on or beneath a surface of a medium;

said sensor connected to the distal end of the reach-in arm by a quick connect-interface configured to provide an automatic disconnect of the sensor from the reach-in arm, said quick-connect interface comprising a contact switch breakaway system and a spring mechanism;

(c) moving said reach-in arm in a specified direction to position the sensor over a surface of a medium; and

(d) moving said sensor in a specified direction over the surface of a medium in search of an object on or beneath a surface of said medium.

19. The method of claim 18 further comprising:

(a) providing a second sensor coupled to the ground penetrating radar sensor for monitoring the distance between said ground penetrating radar sensor from an object in the path of said ground penetrating radar sensor;

(b) detecting an object in the path of said ground penetrating radar sensor;
