Automated stringline installation system
An automated stringline installation system includes a vehicle, a 3D control system, at least partly carried by the vehicle, for determining location information, and an adjustable arm assembly, mounted on the vehicle, that identifies the location of a relative point in a stringline installation using the location information determined by the 3D control system. The adjustable arm assembly includes an operational arm having a proximal end and a distal end, a string, dispensed from the operational arm, for use in a stringline installation, and a sensor used to determine information pertaining to the location of the distal end of the operational arm assembly relative to the proximal end of the operational arm.
1. An automated stringline installation system, comprising:
a vehicle;
a 3D control system, at least partly carried by the vehicle, for determining location information; and
an adjustable arm assembly, mounted on the vehicle, that identifies the location of a relative point in a stringline installation using the location information determined by the 3D control system.
2. The automated stringline installation system of claim 1 , wherein the relative point is a particular point, on the ground, where a stake is to be installed in a stringline installation.
3. The automated stringline installation system of claim 2 , wherein the adjustable arm assembly is adapted to install the stake at the particular point.
4. The automated stringline installation system of claim 1 , wherein the relative point is a particular point, elevated over the ground, through which a string is to be installed in a stringline installation.
5. The automated stringline installation system of claim 4 , wherein the adjustable arm assembly is adapted to position the string such that it is routed through the particular point.
6. The automated stringline installation system of claim 5 , wherein the adjustable arm assembly is adapted to install the string such that is routed through the particular point.
7. The automated stringline installation system of claim 5 , further comprising a reel assembly for carrying a spool of string such that the string may be routed from the reel assembly to the particular point.
8. The automated stringline installation system of claim 1 , wherein the relative point is a particular point, in an existing stringline installation, whose actual location is to be determined.
9. The automated stringline installation system of claim 8 , further comprising a database in which the actual location of the particular point is recorded as installed data.
10. The automated stringline installation system of claim 1 , wherein the adjustable arm assembly includes an operational arm and a translational platform.
11. The automated stringline installation system of claim 10 , wherein the translational platform includes a mechanical assembly that permits the operational arm to be displaced, relative to the vehicle, in one or more degree of freedom.
12. The automated stringline installation system of claim 11 , wherein the operational arm shifts, along at least one axis, relative to the vehicle.
13. The automated stringline installation system of claim 11 , wherein the operational arm rotates, around at least one axis, relative to the vehicle.
14. The automated stringline installation system of claim 11 , wherein the mechanical assembly includes a plurality of adjustment mechanisms, each permitting the operational arm to be displaced in exactly one degree of freedom.
15. The automated stringline installation system of claim 1 , wherein the adjustable arm assembly includes an articulated arm.
16. The automated stringline installation system of claim 1 , further comprising an arm-mounted locator assembly disposed at a distal end of the adjustable arm assembly and arranged to point to the relative point.
17. The automated stringline installation system of claim 1 , further comprising a sensor used to determine information pertaining to the location of a distal end of the adjustable arm assembly relative to the 3D control system.
18. The automated stringline installation system of claim 17 , wherein the sensor determines a state or position of an adjustment mechanism in the adjustable arm assembly.
19. The automated stringline installation system of claim 17 , wherein the sensor determines a distance or angle of a first portion of the adjustable arm assembly relative to a second portion of the adjustable arm assembly.
20. The automated stringline installation system of claim 17 , wherein the sensor determines a distance or angle between the distal end of the adjustable arm assembly and the 3D control system directly.
21. The automated stringline installation system of claim 1 , wherein the 3D control system includes a fixed base station locatable in the general vicinity of the vehicle on a construction site, and a mobile unit carried by the vehicle.
22. The automated stringline installation system of claim 21 , wherein the fixed base station is equipped with GPS and the mobile unit includes a GPS unit.
23. The automated stringline installation system of claim 21 , wherein the base station is a robotic laser-based tracking station and the mobile unit includes a prism.
24. An automated system for installing a stringline that may subsequently be utilized to guide a paving machine during operation thereof, comprising:
a vehicle;
a 3D control system, at least partly carried by the vehicle, for determining geodetic information regarding the location of at least a portion of the vehicle; and
an adjustable arm assembly, mounted on the vehicle, that uses the geodetic location information determined by the 3D control system to identify the location of a point in the stringline that is being installed, thereby facilitating the installation of the stringline.
