The video presents recent progress of the wall-climbing robot project at the City College of New York. The robots are named as City-Climbers which adopt a novel adhesive mechanism based on aerodynamic attraction to achieve good balance between strong adhesion force and high mobility. The video demonstrates that the City-Climber robots can operate on various smooth or rough surfaces and have the capabilities to move on the ground, walls, ceilings, and transit between them. The video also displays the Fluent simulation results of the aerodynamic attraction, and experimental tests of suction force. DSP-based control system is introduced which enables the robot to operate both manually and autonomously.
