On July 31, the award ceremony of the First Guangdong–Hong Kong–Macao Construction Robotics Competition and the Building the Future: Construction Robotics forum was held in Hong Kong. The intelligent heavy-duty assembly robot independently developed by China Railway Academy Co., Ltd. Southwest Institute won the Innovation Star award in the technology R&D competition.
The robot provides an intelligent solution for tunnel steel ring reinforcement and assembly, overcoming technical challenges in multiple modules including the robot body, rail vehicle carrier and leveling system, recognition system, and gripping system. It achieves intelligent recognition and gripping of steel rings, along with automatic path planning, operating fully unmanned. During operation, the assembly error margin of the steel rings is ±2 mm, with leveling accuracy up to ±0.3°. Compared with traditional methods, it reduces labor requirements by 30% and improves overall productivity by about 33%. It has already obtained two invention patents and one utility model patent, with four additional invention patents under review, and has received honors such as the First Set of Major Technical Equipment in Sichuan Province.
It is reported that the competition was guided by the Development Bureau of the Hong Kong Special Administrative Region Government and the Department of Housing and Urban-Rural Development of Guangdong Province. Through competition and exhibitions, the event aimed to discover and support innovative and entrepreneurial talent teams in the field of intelligent construction robotics, promoting integration across the entire industry chain.
