In some examples, an autonomous robotic welding system comprises a workspace including a part having a seam, a sensor configured to capture multiple images within the workspace, a robot configured to lay weld along the seam, and a controller. The controller is configured to identify the seam on the part in the workspace based on the multiple images, plan a path for the robot to follow when welding the seam, the path including multiple different configurations of the robot, and instruct the robot to weld the seam according to the planned path.

Systems and methods for real time feedback and for updating welding instructions for a welding robot in real time is described herein. The data of a workspace that includes a part to be welded can be received via at least one sensor. This data can be transformed into a point cloud data representing a three-dimensional surface of the part. A desired state indicative of a desired position of at least a portion of the welding robot with respect to the part can be identified. An estimated state indicative of an estimated position of at least the portion of the welding robot with respect to the part can be compared to the desired state. The welding instructions can be updated based on the comparison.

A component having a first part and a second part. The first part has a first interface surface and the second part has a second interface surface that is connected to the first interface surface via a bond. A digital profile of the first interface surface is used to shape the second interface surface to fit against the first interface surface with minimal to no gap therebetween before forming the bond. The digital profile is developed by scanning the first part with a scanner and the second part is shape by cutting or milling with a robotic arm that acts in accordance with a digital profile data read by a controller. The two parts are bonded via a weld that is automatically guided by the digital profile.

Embodiments of the present disclosure are directed towards a robotic system and method. The system may include a robot and a three dimensional sensor device associated with the robot configured to scan a welding area and generate a scanned welding area. The system may include a processor configured to receive the scanned welding area and to generate a three dimensional point cloud based upon, at least in part the scanned welding area. The processor may be further configured to perform processing on the three dimensional point cloud in a two-dimensional domain. The processor may be further configured to generate one or more three dimensional welding paths and to simulate the one or more three dimensional welding paths.

A repair welding device includes an acquisition unit configured to acquire an appearance inspection result including information about a position of a defective portion of a weld bead of a welded workpiece produced by a main welding that is executed by a welding robot, and a robot control unit configured to set a plurality of interpolation points on a virtual welding line of the main welding executed by the welding robot and instruct the welding robot to execute a repair welding on an interpolation point that is closest to the acquired position of the defective portion. The virtual welding line is simulated based on a main welding program for executing the main welding.

A memory in which information that is used in a tracking operation is to be temporarily stored, information cannot be accumulated in the memory when the accumulating intervals and the reading intervals do not match each other. A robot control apparatus includes: a memory; an accepting unit that accepts a sensing result of a laser sensor detecting a shape of a working target before an, and accumulates information according to the sensing result, in the memory. The memory management unit that, in a case in which the memory is running short of free space, deletes the information in the memory; and a control unit that moves the working tool based on teaching data, and corrects the movement of the working tool based on the information according to the sensing result stored in the memory.

An example robotic welding system includes: one or more sensors configured to determine a physical position and orientation of a welding tool with respect to a reference frame; and a processor configured to: communicatively connect to a welding-type power supply; during a welding operation performed using the welding tool: track the physical position and orientation of the welding tool within the reference frame; and monitor at least one of an input or an output of the welding-type power supply; and generate a robotic welding procedure based on the tracked physical position and orientation of the welding tool and based on the at least one monitored input or monitored output of the welding-type power supply.

A torch for use by a robot. The torch has a body that can be connected to an arm of the robot. A first actuator on the body can be activated by a user to initiate a recording cycle at a starting point of a desired welding or cutting path and to terminate the recording cycle at an ending point of the path. A second actuator on the body can be activated by the user to indicate way points from the starting point to the ending point as the user moves the torch along the path. The first actuator sends first information to a robot controller, operatively connected to and located remotely from the robot, to initiate and to terminate the recording cycle at the controller. The second actuator device sends the way points as second information to the controller to be recorded at the controller during the recording cycle.
