Autonomous mobile construction robots in built environment: A comprehensive review

Combined robotic arms and mobile platforms, mobile construction robots(MCRs) are providing an energizing choice for the digitalization of the building industry. To enhance the comprehension of the research trajectory towards MCR applications and technologies in building construction, we focus on the following aspect: Current representative applications of MCRs in built environments and critical technologies involved. This comprehensive review identified 184 publications in the last 15 years to unravel MCRs in construction applications, scrutinized the crucial technologies involved, and deliberated on challenges and opportunities. Results indicate that MCRs are a growing application field, although the majority are still confined to laboratory settings. To further expand the application of MCR in construction scenarios, this paper proposes corresponding research roadmaps to address the challenges identified. The findings of this review provide an in-depth insight into digital construction and robotics, benefiting researchers and constructors in advancing robotic commercialization.
