Aerodynamic analysis of City-Climber robots

A multi-disciplinary robotics team at the City College of New York has developed a new generation wall-climbing robot named as City-Climber, which can operate on both smooth and rough surfaces and carry relatively large payload. This paper presents the adhesion mechanism and aerodynamic analysis of City-Climber robots using a computational fluid dynamics (CFD) simulation tool. The simulation results not only match the experimental test but also provide the directions to improve the adhesion mechanism design.
