Patent number: 10926407Abstract: Systems and methods are provided for controlling the motion of a tracked robot assembly. An exemplary method comprises disposing a mobile robot assembly proximate to a fuselage of an aircraft that is being assembled, aligning a left ranging sensor of the assembly with a left target, and aligning a right ranging sensor of the assembly with a right target. The method also includes directing the assembly to traverse to a location within the aircraft fuselage at which a robot on the assembly will perform work upon the fuselage, determining a left distance between the left ranging sensor and the left target while the assembly is moving, determining a right distance between the right ranging sensor and the right target while the assembly is moving, detecting a difference between the determined distances, and adjusting a direction of motion of the assembly based on the difference.Type: GrantFiled: August 24, 2016Date of Patent: February 23, 2021Assignee: The Boeing CompanyInventors: Arun Ayyagari, Thi Q Nguyen, Ngoc S Le, Bally Bang, Wen Xin Wang, David H Amirehteshami

Patent number: 9817402Abstract: Work cell and factory level automation require that an Automated Guided Vehicle (AGV) achieve demanding positional accuracy and repeatability relative to a cradle fixture or workstand within a work cell. The AGV makes distance measurements of objects within the work cell using laser scanner sensors. The distance measurements are filtered of objects that are not target features on the cradle fixture or workstand. Systematic or bias errors of the laser scanner sensor are removed from the filtered distance measurements, and a mathematical filter or estimator is applied to the filtered distance measurements using random errors of the laser scanner sensor to generate estimated distance measurements. A map of the target features is then constructed using the estimated distance measurements, wherein the map is used for path planning and navigation control of the AGV relative to the cradle fixture or workstand within the work cell.Type: GrantFiled: July 12, 2016Date of Patent: November 14, 2017Assignee: The Boeing CompanyInventors: Arun Ayyagari, Thi Q.

Patent number: 8301302Abstract: A fully automated method is performed on a structure having a confined space. The structure has a location that is identifiable from within the confined space and from outside the confined space. A first robotic system moves a first end effector inside the confined space such that the first end effector is positioned over the location. A first vector corresponding to the location is generated. A second robotic system moves a second end effector outside the confined space such that the second end effector is positioned over the location. A second vector corresponding to the location is generated. The first and second vectors are used to move the first and second end effectors to a new location such that the first and second end effectors are in working opposition. The first and second end effectors perform a synchronous operation at the new location.Type: GrantFiled: May 8, 2008Date of Patent: October 30, 2012Assignee: The Boeing CompanyInventors: Branko Sarh, David H. Amirehteshami

Patent number: 7627940Abstract: Methods are disclosed for producing a hole in a work-piece having first and second layers of material. The first layer of material contains a full-sized hole through the first layer of material. The first layer of material is positioned adjacent the second layer of material. An orbital drill is secured to the first layer of material to position a cutting tool of the drill within the through-hole. During operation, when the cutting tool is used to cut a hole in the second layer of material, the alignment keeps the orbital drill stationary.Type: GrantFiled: July 13, 2005Date of Patent: December 8, 2009Assignee: The Boeing CompanyInventors: David H.
