A robotic welder includes one or more motors, one or more articulating arms connected to the one or more motors, one or more sensors configured to image a wear plate for determining welding locations for welding the wear plate to a blade of a machine, and an orbital welder to rotate a torch head for welding the wear plate to the blade.

A system for positioning a tool or a component on a workpiece may include a laser configured to project a laser point on the workpiece. The laser may include a field of view and the laser may project the laser point upon objects within the field of view of the laser. The system for positioning a tool on a workpiece may also include a fixture configured to position the tool on the workpiece. The fixture may include a laser indicator configured to be aligned with the laser point projected on the workpiece. The fixture may also include a first tool receptacle configure to receive the tool and locate the tool on a portion of the workpiece outside the field of view of the laser.

Laser projection hardware positional device

A structural member includes a body having a first surface, a second surface, and an end surface at an end portion of the structural member. The end portion of the structural member includes a root protrusion extending radially outward from the second surface of the structural member along a root protrusion radius to an outer end of the root protrusion to define a root protrusion height extending from the second surface of the structural member to the outer end of the root protrusion. The root protrusion further includes a root protrusion width extending between an inner edge and an outer edge of the outer end of the root protrusion. The root protrusion radius, the root protrusion height, and the root protrusion width are configured to define a stress protected weld root region isolated beyond and away from a root stress flow path propagated through the body of the structural member.

A structural member is disclosed. The structural member includes a body having a first surface, a second surface, and an end surface at an end portion of the structural member. The end portion of the structural member includes a root protrusion extending radially outward from the second surface of the structural member along a root protrusion radius to an outer end of the root protrusion to define a root protrusion height extending from the second surface of the structural member to the outer end of the root protrusion. The root protrusion further includes a root protrusion width extending between an inner edge and an outer edge of the outer end of the root protrusion. The root protrusion radius, the root protrusion height, and the root protrusion width are configured to define a stress protected weld root region isolated beyond and away from a root stress flow path propagated through the body of the structural member.

A tip attachment is disclosed. The tip attachment may an attachment body including a recess to fit on or in a tip of a device during programming of a robotic device. The attachment body may be structured such that the attachment body defines a set of angles of the tip during the programming of the robotic device. The recess may be sized such that the recess defines a distance between the tip and a workpiece during the programming of the robotic device.

A retention clip used to retain workpieces during welding includes a spacer that extends along an axis and a plurality of first and second spring members positioned on opposite sides of the axis. The first spring members may be spaced apart from each other along the axis and configured to constrain a portion of a first workpiece between the first spring members and the spacer. And, the second spring members may be spaced apart from each other along the axis and configured to constrain a portion of a second workpiece between the second spring members and the spacer.

Clip for retaining components for welding

A node is disclosed. The node may have a core. The node may also have a projection extending from the core. Further the node may have a structural member attached to the projection. The node may also have a top cover having a top recess. The top recess may be configured to receive the structural member. Additionally, the node may have a bottom cover having a bottom recess. The bottom recess may be configured to receive the structural member. In addition the node may have a fastener to connect the top cover and the bottom cover.

Node for a space frame

A drilling drive system is provided. The drilling drive system has a mast having a longitudinal axis and a surface extending along the longitudinal axis. A bar is fixed to the surface of the mast and extends along the longitudinal axis. A plurality of rungs is disposed along the length of the bar, and a floating chain is disposed around the mast. A drive sprocket has a plurality of teeth that engage the plurality of rungs and the floating chain.
