摘要： A climbing vehicle with wheel or endless-track type propulsion using suction for generating adhering forces is adapted to climbing non-planar surfaces such as intersecting walls, pipes or other structural members. The suction chamber is relatively fixed to the vehicle chassis and moves with the vehicle chassis. A seal is created around the suction chamber through an adaptive sealing mechanism. The adaptive sealing mechanism consists of a series of links that adapt to the climbing surface geometry and forms a seal at the climbing surface. The links in the adaptive sealing mechanism span a portion of the suction chamber along the longitudinal sides of the vehicle and are elastically sprung to maintain contact with the surface. The adaptive sealing mechanism links also span the lateral sides of the vehicle to fully enclose the suction chamber. Thus, the suction chamber is maintained even as the mobile vehicle passes over significant geometry changes in the climbing surface, for example transitioning between surfaces that are orthogonally opposed.

摘要： This patent discloses a climbing vehicle capable of high payload to weight ratio and capable of climbing surfaces with geometric variations and traveling along a single dimension. More specifically, this invention applies to a vehicle well adapted to climbing non-planar surfaces such as pipes or other structural members while traveling along a single dimension, for example traveling parallel to the axis of the pipe. The climbing vehicle makes contact with the climbing surface through drive wheels and a trialing arm. The adhering members are aligned with the primary axis and are rigidly attached or contained in a suspension that is able to conform to a large range of surface irregularities while providing push and pulling forces between the adhering members and the climbing vehicle chassis to uniformly distribute the climbing loads on the adhering members. The result is a climbing machine that can accommodate large surface irregularities while maximizing the climbing payload with a minimum number and size of adhering members.

摘要： A Mobile Climbing Robot (MCR) with wheel or endless-track type propulsion using magnetic attraction for generating adhering forces is adapted to climbing non-planar surfaces such as intersecting walls, pipes or other structural members. A tether is connected to the MCR through a tether linkage that causes the tether to bend with a radius that keeps it from protruding outside of the MCR wheels. The purpose of this is to increase the mobility when passing over variations of the climbing surface such as edges or corners. The purpose is to further protect the tether from wear caused by rubbing with the climbing surface.

摘要： This patent discloses a climbing vehicle capable of high payload to weight ratio and capable of climbing surfaces with geometric variations and traveling along a single dimension. More specifically, this invention applies to a vehicle well adapted to climbing non-planar surfaces such as pipes or other structural members while traveling along a single dimension, for example traveling parallel to the axis of the pipe. The climbing vehicle makes contact with the climbing surface through drive wheels and a trailing arm. The adhering members are aligned with the primary axis and are rigidly attached or contained in a suspension that is able to conform to a large range of surface irregularities while providing push and pulling forces between the adhering members and the climbing vehicle chassis to uniformly distribute the climbing loads on the adhering members. The result is a climbing machine that can accommodate large surface irregularities while maximizing the climbing payload with a minimum number and size of adhering members.

摘要： Robots are commonly used for automated MIG (Metal Inert Gas) or TIG (Tungsten Inert Gas) welding in many industries such as automotive manufacturing. A weld procedure is defined and the robot performs motion control of the weld torch along the weld seam, while starting and stopping the arc as desired along the weld seams. The robot controls the motion of the torch along the weld path. The motion is defined by a combination of the position and orientation of the torch which is attached to the robot end-effector. The weld specification will generally prescribe a portion or all of the desired orientation of the torch. This information can be used to reduce the complexity of programming a weld path for a robot.

摘要： Abstract of the Disclosure The Invention describes a method to train and edit robot programs without the need to directly interact with the robot program or code. A new program is created by guiding the robot to desired locations in the program and then teaching those program positions with a button or similar input. An existing program is edited by moving the robot end-effector to a position in its workspace that is near the desired location of the program to be edited. An algorithm then is used to find the nearest program point in the existing program to the current robot end effector position. The algorithm then drives the robot to this nearest location. The operator can then visually confirm that this is the correct point in the program to edit, or move the robot again and repeat the algorithm search. Once the operator is satisfied that the robot is at the location of the program to edit, the operator can delete that point by pressing an appropriately labeled button. The operator could also add positions by first finding an edit point in the program using the manual move near the edit point and then running the search algorithm. The operator will then move the robot to the new position and press a button or input to add this new program position to the program. This process can be repeated as needed to edit the program. In this manner, the weld technician is not required to interact with code that defines the robot program but rather work with the end effector to spatially position the end-effector and edit the program.

摘要： This patent defines a method for making robot programming more intuitive for tasks such as welding. The method further is an enhancement of manual guiding methods of robot positioning and can improve situations in which finer resolution or control of the robot end-effector is required. A motion sensor is mounted in series with the n−1 joint and in parallel with the nth joint, where n is the number of degrees of freedom or number of joints of the serial manipulator. The motion sensor is further mounted directly in-line with the nth joint and becomes part the opposing portion of the nth joint. The motion sensor further is uniquely adapted to apply to non-spherical wrist robots. The motion sensor senses input movements by a robot operator and controls the output tool motion in a controlled manner with resolution defined by user input at the motion sensor.
