Autonomous apparatus and system for repetitive tasks in construction project

摘要

An autonomous assembly that includes a gantry subassembly, a carrier subassembly movably mounted on the gantry subassembly, a tool actuation subassembly mounted on the carrier subassembly, and an autonomous control system including a perception subsystem, a motion planning subsystem, and a motion control subsystem. The gantry subassembly includes a bridge member for laterally spanning a selected section of a work site and a gantry drive system for effecting travel of the gantry subassembly along a first path, generally in a longitudinally along the length of the selected portion of a work site. The carrier subassembly includes a carriage and a carriage drive system for effecting travel of the carriage along a second path, generally laterally along the bridge member. The tool actuation subassembly includes a motion actuator, an end-effector operatively connected to the motion actuator, and an actuator drive system for effecting linear travel of an end-effector along a third path, generally perpendicular to the second path.
