Castor Construction Robotics Limited

Company

Castor Construction Robotics Limited, founded in October 2024 and headquartered in Hong Kong, is a pioneering enterprise committed to delivering intelligent hardware solutions for the construction industry. Inspired by nature's master builders - beavers, renowned as exceptional architects and dam engineers, we focus on transforming the construction landscape through innovative robotic technologies. As an incubated company of the Hong Kong Center for Construction Robotics under the leadership of Professor Li Zexiang, we specialise in developing cutting-edge solutions including rebar-tying robots, intelligent rebar cutting production lines, and customised robotic solutions incorporating robotic arms.

Much like beavers that meticulously construct dams to create sustainable ecosystems, we are dedicated to developing smarter, safer and more efficient construction processes. Our mission is to empower the construction industry through automation and intelligent technologies, reducing labour costs, enhancing precision, and promoting sustainable development. At Castor Construction Robotics, we are not merely manufacturing robots - we are building the future of the construction industry.

The Rebar Tying Robot, independently developed by Castor Construction Robotics Limited, is designed for diverse planar rebar tying applications across multiple construction sectors It excels in housing projects, infrastructure development (including roads, bridges, and tunnels), commercial complexes, medical facilities, dam constructions, and industrial plants. With its autonomous recognition and positioning system, automatic obstacle avoidance capability, and intelligent track-changing function, the robot efficiently automates large-scale rebar tying operations in mesh central zones.

With a remarkable efficiency of 400-500 nodes per hour, the robot achieves 2-3 times the productivity of manual labour in a standard 8-hour shift. The system offers flexible remote operation through either a dedicated tablet or smartphone app, with an extended control range of up to 50 meters. Powered by advanced multi-sensor fusion technology, the robot maintains millimetre-level precision in all conditions - day or night, under scorching sun or heavy rainfall. Its exceptional environmental adaptability extends to material compatibility, including specialised applications with non-metallic reinforcements like fibreglass rebar mesh.

This rebar tying robot has won multiple awards, including the Hong Kong Construction Industry Council Innovation Award, the Gold Medal with the congratulations of the Jury (Highest Award) at the 49th International Exhibition of Inventions Geneva, the Hong Kong Innovation and Technology Award, and the Hong Kong Awards for Industries: Equipment and Machinery Design. It significantly promotes automation and intelligence in construction sites, alleviating labour shortages and reducing the high risks associated with manual rebar tying.
