An improvement to a semi-autonomous apparatus is described herein. In an apparatus having a gantry subassembly, a tram subassembly movably mounted on the gantry subassembly, and an actuation subassembly mounted on the tram subassembly, the improvement includes a gripper subassembly operatively connected to the actuation subassembly. The movement of the subassemblies is controlled in part by a control system that controls drive systems associated with one or more of the subassemblies. The gantry subassembly includes a bridge member for laterally spanning a selected section of a work site. The tram subassembly includes a tram that travels laterally along to the bridge member. The actuation subassembly includes at least one motion actuator for controlling the movement of the gripper subassembly in a generally vertical direction and may include an additional motion actuator for movement in a generally horizontal direction. The gripper subassembly includes passively actuated grippers for lifting, transporting and placing objects, and particularly, elongate objects such as reinforcing bars used in road and other cementitious surface construction.

Semi-autonomous system for carrying and placing elongate objects

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.
