This E-Team is developing the City-Climber, a wall-climbing robot intended for use in the inspection of building facades. New York City law mandates the inspection of building facades every five years, and the task is currently accomplished by lowering three trained workers down the side of the building by scaffold equipment. Each additional drop to reach other areas of the façade requires a complete relocation of the rigging equipment, making the process time-consuming and expensive (the cost for one day can exceed $3,000). The E-Teams robot adheres to the wall by employing aerodynamic attraction produced by a vacuum rotor package. Cameras and sensors inside the robot are used to assess the condition of the building façade, and the robot itself is remotely operated by a joystick.
