Autonomously and Mechanically Enforces Absolute Positional and Geometric Precision of the Construction Stud Prior to Robotic Pickup
This mechanical-based autonomous material supply station (AMSS) precisely completes industrial construction tasks. Robotics hold immense potential to transform the industrialized construction sector by enhancing productivity, drawing on its similarities with the manufacturing industry. Traditional systems for handling construction materials, such as wood or steel studs, often rely on manual labor or semi-automated equipment to store, position, and feed materials, leading to inefficiencies, inconsistent placement, and increased labor costs. While robotics have a potential application in industrialized construction, the unique project-based nature of construction and the demand for customized building designs present technological hurdles for incorporating robotics into activities. There is ample room in this market for fully automated, efficient machinery.
Researchers at the University of Florida have developed a fully autonomous material supply station designed to improve efficiency and precision in stud handling to address these limitations. The system uses a magazine-style storage unit that holds a single stack of studs and incorporates adaptive holding mechanisms to securely manage the material. This system minimizes human intervention while maintaining consistent, reliable, and precise operations.
Application
Multi-robot system equipped with multifunctional prefabrication end-effectors for completing industrialized construction tasks precisely and efficiently
Advantages
- Upgraded storage system with standardized stainless steel plates, allowing for the precise and distinct adjustment of stud widths
- Upgraded modular stud magazine, automating lateral support for the studs
- Replaces the modular support systems with simple leveling legs, improving the system’s efficiency
- The adaptive stud guiding system is compact, facilitating guided horizontal and vertical movements for the studs
- The system is designed around a compact, magazine-style storage footprint and is reconfigurable and expandable, enabling it to accommodate a broad variety of wood and steel studs required in modern construction
- Enforces absolute positional and geometric precision of the construction stud prior to robotic pickup, offloading complex error correction from the assembly robot
- Employs sensor-based temporal and synchronized positional actuation to replenish the wood studs post-robotic pickup, maintaining the absolute positional accuracy required by the robotic system
Technology
This mechanical-based autonomous material supply station (AMSS) is a streamlined version of the automated precision supplying and cutting station. The innovation in this autonomous material supply station lies in the AMSS’s ability to autonomously and mechanically enforce absolute positional and geometric precision of the construction stud prior to robotic pickup, offloading complex error correction from the assembly robot itself. This precision is achieved through a set of integrated and synchronized mechanisms, allowing the AMSS to support automated, semi-automated, or manual assembly with reliability. The system is designed around a compact, magazine-style storage footprint and is reconfigurable and expandable, enabling it to accommodate a broad variety of wood and steel studs required in modern construction. The magazine-style storage system has an adaptive stud inventory management mechanism and is configured to hold a single stack of construction studs. It then uses a sensor-based autonomous positioning system with adaptive pusher mechanisms to replenish the studs once picked up by a robot. This ensures accurate placement of the construction material.
The AMSS contains three major upgrades, improving overall reliability and reducing system complexity. First, it replaces the aluminum tracks with standardized stainless-steel plates, allowing for precise stud widths. Secondly, it upgrades many of the original aspects of the station to improve efficiency, lowering maintenance requirements and minimizing potential points of failure. Lastly, it eliminates the precision cutting system, resulting in a more cost-effective and dependable solution for material handling in high-throughput production environments.
