    Abstract: 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.

    Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, which provide for welding techniques for manufacturing robots, such as seam localization, gap measurement, or both. For example, the welding techniques may include, during illumination of one or more objects by a light source, controlling a camera to capture images of the one or more objects along at least a portion of a length of a seam formed by the one or more objects. The techniques further include differentiating, in the images, the seam from the one or more objects. In a first aspect, the techniques also include triangulating the differentiated seam to identify a position of the seam relative to a reference point. In a second aspect, the techniques also include determining, based on the differentiated seam, gap information along a portion of the seam. Other aspects and features are also claimed and described.

    Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, that provide for welding techniques for manufacturing robots, such multipass welding techniques for welding robots. For example, the welding techniques may enable generation of weld instructions based on a welding fill plan. The instructions may be generated based on a bead model or a table that indicates a wire feed speed, a travel speed, or a voltage. As another example, the techniques may enable generation of weld instructions based on the one or more dimensions of a seam. As another example, the techniques may enable generation of a joint model of a cross-section of a seam to be welded. The joint model may be generated based on a combination of a plurality of feature components to generate the joint model of the seam. Other aspects and features are also claimed and described.
