Robotics has revolutionized global construction, boosting productivity and safety while advancing sustainable cities. However, its adoption in Nigeria faces major obstacles. This study identifies key barriers hindering robotics adoption in the Nigerian built environment. A quantitative approach was employed, using a structured questionnaire based on a comprehensive literature review. Data analysis involved mean item score, exploratory factor analysis, the Mann-Whitney U test, and frequency distribution. Results highlight electricity supply limitations, high initial costs, and workforce displacement concerns as primary barriers. Four critical barrier groups emerged: investment in innovation, environmental impediments, technological gaps, and resource and risk concerns. The Mann-Whitney U test revealed significant differences in perceptions between indigenous and foreign firms. Addressing these challenges can drive robotics adoption, enhancing efficiency, safety, and innovation while fostering sustainable development in Nigeria's construction sector.
