Multimodal Ultra-Thin Light Robots to Change Inspection and Maintenance Methods
Researchers for the Rolls-Royce University Technology Centre in Manufacturing and On-Wing Technology at the University of Nottingham developed a technology of ultra-thin light robots intended for inspection of narrow spaces in challenging construction conditions.
The developed robots are of just 1.7 mm enabling them to access and navigate in confined spaces, such as millimeter-wide gaps beneath doors or within complex machinery. They have a multi-layer structure driven by dielectric elastomers, allowing them to crawl, climb, swim and transition between solid and liquid domains. This adaptability makes them ideal for complex environments that include multiple obstacles across various terrains.
Multimodal locomotion capabilities are set to transform inspections and maintenance methods at power plants, bridges and aero engines, etc.
Preliminary tests have already demonstrated the potential of robots in real-world conditions, including the inspection of electrical generators of advanced hybrid-electric power systems. The robots successfully navigated the narrow air gap between the rotor and stator of a generator, a feat that traditional tools and robots cannot achieve.
The researchers plan to further optimize the robots’ design and explore new applications in sectors such as aerospace and energy maintenance and nuclear decommissioning.
