Abstract: The disclosed systems for automated building construction may include upright supports, a support platform coupled to and vertically movable relative to the upright supports, and a bridge platform coupled to and horizontally movable along the support platform. A track may be mounted on the bridge platform, and a robotic arm may be coupled to and movable along the track. The robotic arm may be configured to retrieve structural insulated panels and to position the structural insulated panels to construct at least a portion of a building. Various other related systems and methods are also disclosed.

Abstract: The disclosed friction bit joining systems may include a ball screw having an internal bore, a chuck and spindle configured to be rotated by a chuck spindle motor, a friction bit joining bit held by the chuck, a support frame, and a chuck driver motor positioned and configure to rotate the ball screw to axially move the chuck and the friction bit joining bit relative to the support frame. At least a portion of the spindle may be positioned within the internal bore of the ball screw. Various other related systems and methods are also disclosed.
