Patent number: 10913158Abstract: A robotic system includes a robotic arm, a base couple coupled to the robotic arm, and a controller. The robotic supports a work implement and is configured to move the work implement to perform an operation on a workpiece. The base is configured to be removably coupled to a mounting surface. The controller is in communication with the robotic arm, the work implement, and the base. Further, the controller is configured to disable the operation of at least one of the robotic arm and the work implement if a coupling parameter between the base and the mounting surface is below a threshold value.Type: GrantFiled: May 14, 2018Date of Patent: February 9, 2021Assignee: Caterpillar Inc.Inventors: Jeremy Roe Hammar, Leon R. Adcock, Bradley Phillip Graham, Matthew J. Behmlander, Joshua Clifton Short, Donald A. Stickel, III

Patent number: 9649966Abstract: A truck body for a machine is disclosed. The truck body has a bottom wall defining a front end and a rear end, a pair of lateral walls extending from the bottom wall, and a front wall extending between the pair of lateral walls at the front end. The truck body includes a pair of bottom beams pivotally coupled to a frame of the machine. The truck body further includes a plurality of tubes disposed on the pair of bottom beams. Each of the plurality of tubes is disposed adjacent to each other to at least define the bottom wall and the pair of lateral walls of the truck body.Type: GrantFiled: June 2, 2015Date of Patent: May 16, 2017Assignee: Caterpillar Inc.Inventors: Huijun Wang, Donald A. Stickel, III, Howard W. Ludewig, Danny L. McCaherty

Patent number: 9545693Abstract: A consumable insert for welding a first component to a second component is provided. The first component is positioned with respect to the second component in such a manner that a gap is defined between adjacent surfaces thereof. The consumable insert includes a body having a profile. The profile of the body matches a scan of a profile of the gap between the adjacent surfaces. The consumable insert also includes a dam portion having a profile. The profile of the dam portion matches, at least in part, a scan of corresponding surfaces of the first component and the second component respectively. The dam portion is provided in contact with at least one end of the body. The dam portion is configured to control an overflow of a weld puddle therefrom. The body and the dam portion are formed using three dimensional printing.Type: GrantFiled: October 7, 2014Date of Patent: January 17, 2017Assignee: Caterpillar Inc.Inventors: Huijun Wang, Leon R. Adcock, Kendall R. Powell, Donald A. Stickel, III, Howard W. Ludewig

Publication number: 20150314407Abstract: A method to join a first enclosed workpiece and a second enclosed workpiece is provided. The first enclosed workpiece includes a first connecting end and a first cavity region. The second enclosed workpiece includes a second connecting end and a second cavity region. A backing member is placed in the first connecting end, with a first end within the first cavity region. A resilient member is positioned in the first cavity region, with a first portion within the first cavity region. The second enclosed workpiece is positioned proximal to the first enclosed workpiece to define a gap between the first connecting end and the second connecting end. Upon positioning, a second end of the backing member and a second portion of the resilient member are placed within the second cavity region. The first connecting end is then welded with the second connecting end over the backing member near the gap.Type: ApplicationFiled: July 14, 2015Publication date: November 5, 2015Applicant: Caterpillar Inc.Inventors: Huijun Wang, Yan Shao, Ronald T.
