A control system for controlling operation of an implement based, at least, on a pre-determined implement control plan, includes a relative positioning system, a controller, and one or more actuators. The relative positioning system is configured for determining positioning of the and utilize input from perception sensors to determine relative positioning signals. The controller is configured to determine a resume position for a next operation of the implement based on the predetermined implement control plan and at least one of the relative positioning signals and an end position of a previous operation of the implement. The controller may further be configured to determine implement control signals based on, at least, the resume position. The one or more actuators are each operatively associated with one or both of the implement and machine and configured to receive the implement control signals and position the implement based on the implement control signals.

A system for manufacturing a tower structure of a wind turbine includes an additive printing device having a central frame structure with a platform and an arm member. The arm member is generally parallel to a longitudinal axis of the tower structure. The additive printing device also includes a plurality of robotic arms secured to the arm member of the central frame structure. Each of the robotic arms includes a printer head for additively printing one or more materials. The additive printing device further includes at least one nozzle configured for dispensing a cementitious material. Moreover, the system includes one or more molds additively printed via the additive printing device of a polymer material. As such, the mold(s) define inner and outer wall limits of the tower structure. After the mold(s) are printed and solidified, at least one of the printer heads or the nozzle of the additive printing device is configured to dispense the cementitious material between the inner and outer wall limits of the tower structure.

A mast arm for a concrete distributor mast comprises an elongated box profile support composed, in at least some sections, of a lower belt, an upper belt, and two lateral walls that connect the belts, and comprising at least one partition sheet metal element arranged in a hollow cross-section of the box profile support, the partition sheet metal element being welded to the box profile support along longitudinal welding joints running along the box profile support.

A method for manufacturing a tower structure of a wind turbine includes additively printing at least a portion of a frame shape of the tower structure of the wind turbine of a first material on a foundation of the tower structure. Further, the first material has a first cure rate. The method also includes allowing the portion of the frame shape to at least partially solidify. The method includes providing a second material around and/or within the portion of the frame shape such that the portion of the frame shape provides support for the second material. The second material includes a cementitious material having a second cure rate that is slower than the first cure rate, with the different cure rates reducing the net printing time for the overall structure. Moreover, the method includes allowing the second material to at least partially solidify so as to form the tower structure.

An additive printing device and a method for using the same to manufacture a tower structure of a wind turbine is provided. The additive printing device includes a vertical support structure, a support ring suspended from the vertical support structure, and a printer head movably coupled to the support ring for selectively depositing cementitious material. A drive mechanism, such as a rack and pinion, moves the printer head around the support ring while selectively depositing cementitious material. The vertical support structure may be raised and/or the relative position between the vertical support structure and the printer head may be adjusted to raise the printer head to print subsequent layers. This process may be repeated to print the tower structure layer-by-layer from the ground up.

A method for manufacturing a tower structure of a wind turbine includes printing, via an additive printing device, the tower structure of the wind turbine of a cementitious material. During printing, the method includes embedding one or more reinforcement sensing elements at least partially within the cementitious material at one or more locations. Thus, the reinforcement sensing element(s) are configured for sensing structural health of the tower structure, sensing temperature of the cementitious material, heating to control cure time of the cementitious material, and/or reinforcing the cementitious material. In addition, the method includes curing the cementitious material so as to form the tower structure.
