Mr. Zhang Zhixiang, Founder and President of Legend Robot Technology, recently participated in an in-depth interview with HC Coating Network. The discussion delved into how construction robots address industry labor shortages and efficiency bottlenecks, alongside Legend Robot’s innovative practices and strategic roadmap. As a "dream builder" dedicated to bridging traditional construction and advanced robotics, Zhang shared the philosophy and ambition behind the company’s three-year journey to overcome industry challenges.
When the global construction sector faces critical labor shortages and efficiency bottlenecks, a Shenzhen-based start-up has achieved a remarkable leap from R&D to large-scale commercialization in just three years. Like the "magpie" implied by its name, Zhang Zhixiang and Legend Robot Technology are steadfastly building a solid bridge for traditional construction to the intelligent future through robotic technology.
Bridging Traditional Construction and Advanced Robotics: The "Magpie Bridge" Vision
“In Chinese folklore, the magpie builds a bridge across the Milky Way. Inspired by this imagery, I named the company 'Legend Robot' (literally, ‘Leading Magpie’) to symbolize our mission: replacing manual labor in construction with intelligent robots,” Zhang said. “The construction industry and robotics are like two sides of the galaxy—we want to be the magpie that builds the bridge between them. Let robots do the work; we’ll automate the connection.”
This poetic metaphor reflects a clear strategic position. Legend Robot Technology positions itself as a driving force in the construction robotics ecosystem. As a core equipment developer, the company deeply understands industry pain points and continues to iterate on its robotic product line. It empowers equipment operators through leasing or sales models and ultimately serves construction clients by driving efficiency gains across the sector. “We’re not just pioneers—we’re a key engine powering transformation across the value chain,” Zhang emphasized.
Empowering Industry with Intelligence, Safeguarding Workers with Dignity
"Empower Construction with Intelligence, Elevate Labor with Dignity"—this mission, written by Zhang himself, is embedded in the genetic code of Legend Robot’s products.
To fulfill the promise of intelligence, Legend Robot has stuck firmly to the path of true autonomy from the outset. While the industry debated whether full automation was necessary, Zhang was clear: “Remote control may be easier and cheaper, but only autonomous perception and unmanned operation can truly transform construction.” Backing this conviction with investment, Legend Robot became the first in the field to realize full-stack capabilities for environmental sensing and autonomous decision-making.
The company’s proprietary IoT system monitors equipment status in real time and collects massive construction data. Despite increasing operational costs, Zhang insists on offering this system free for clients. “If we want a smarter industry, profits can take a back seat,” he stated.
As for protecting worker dignity, Legend Robot prioritizes use cases with the greatest health risks. “Paint spraying sites are filled with dust—even in protective gear, my formaldehyde allergy made it unbearable within 15 minutes,” Zhang recalled. “The noise and dust from floor grinding are just as harmful.” His personal experience reinforced the decision to target these hazardous tasks first, replacing human exposure with robotic intervention.
Breaking Technical Barriers: Self-Perception & Decision-Making Redefine Industry Heights
At the core of Legend Robot’s six-product portfolio lies a fundamental differentiator: perception and decision-making capabilities. Unlike industry solutions reliant on preloaded CAD/BIM drawings, Legend’s robots possess deep spatial understanding. They identify points, lines, and surfaces to reconstruct a 3D model of the job site with millimeter-level precision.
“In construction, deviations are the norm. The gap between paper drawings and real-world conditions is where traditional automation fails,” Zhang explained. Legend’s robots boast 99.9% accuracy in object classification and precise dimensional recognition, enabling them to autonomously generate operational plans for complex site conditions.
“The real breakthrough lies in perception and decision-making,” Zhang reiterated. Legend continues to invest heavily in these pillars—expanding environmental perception from indoor to outdoor environments, scaling object recognition from hundreds to thousands of categories, and optimizing AI-driven planning algorithms for greater efficiency.
Dual-Focus Strategy: Residential & Public Buildings, with Vertical & Horizontal Expansion
Legend Robot has focused on the two largest construction scenarios—residential and public buildings—ensuring both technological adaptability and commercial scalability. Looking ahead, its roadmap is clear: vertical deepening to cover more construction processes, and horizontal extension into new phases of the building lifecycle.
“Currently, we focus on paint spraying, tile laying, and floor grinding,” Zhang said. “But a single building involves dozens of processes.” The company plans to expand its robotic product chain to fill these gaps.
Horizontally, Zhang sees opportunity beyond construction: “Building is only the beginning of a space’s life cycle. As our robots mature, they can extend into operation, maintenance, and service—opening up entirely new markets.”
Vision of a Bridge Builder
As the construction industry evolves toward intelligent transformation, Zhang Zhixiang and Legend Robot are delivering on the "magpie bridge" promise. Their work is redefining construction—faster, more accurate, and less labor-dependent—while lighting the way to a smarter, more humane, and more sustainable future for the industry.
Legend Robot’s path—powered by innovation and responsibility—deserves continued attention. As the “dream-building magpie” takes flight, it may well guide China’s construction sector into a new era of robotics.
