A Robust High-Strength Multi-Surface Rapid UV-Curable Payload Installation System for Generic Multirotors via Impact Delivery

This letter details the design and development of a novel 3D-printed, lightweight and rapid-curing automated payload installation system for aerial robots, using a 3D printed resin-filled adhesive carrier tile (ACT). Its structure is designed to fracture and disperse ultraviolet (UV) curable resin on impact, delivered with a lightweight spring-driven impactor that rams the tile against a target surface. The dispersed resin is then cured with UV light. Shear-testing experiments with 40 × 40 mm ACTs across common building materials, surface conditions and roughness demonstrate loading exceeding 900 N only after 10 seconds of curing, showcasing the strength, robustness and speed of the proposed system. Automated payload installation experiments show potential for applications requiring strong and permanent bonds to wall structures, such as sensor payloads or tether points within urban environments. To the authors' knowledge, this is the first work employing wet UV adhesives for payload installation via multirotors.
