A wall climbing robot using propulsive force of propeller

A Survey of Technologies and Applications for Climbing Robots Locomotion and Adhesion

“…Finally, their application has also been proposed in the education (Bell and Balkcom (2006); Berns et al (2005)) and human care (Balaguer et al (2005)) areas and in the prevention and fire fighting actions (Chen et al (2006);Nishi (1991)). …”

“…The propulsion type robots make use of the forces developed by propellers to move and to adhere to the surfaces (Nishi (1991)), but are used in very restricted and specific applications. Nishi (1991) developed a climbing robot using the thrust force of propellers to locomote (Figure 5).…”

“…Nishi (1991) developed a climbing robot using the thrust force of propellers to locomote (Figure 5). The contact between the robot and the surface is maintained though a large number of non-actuated wheels.…”

OmniClimbers: Omni-directional magnetic wheeled climbing robots for inspection of ferromagnetic structures

“…For holding a robot attached to a smooth surface, the mainly used systems are: suction cups [1], [2], [3], [4], attraction force generated by propeller (negative pressure) [5], [6] or magnets [7], [8], [9], [10]. Other new systems such as biological inspired adherence through wet or dry adhesion and electro adherence have also been developed (See [11] for instance).…”

City-Climber: A New Generation Wall-Climbing Robots

“…These constraints greatly limit the application of the robots. The third choice is to create attraction force based on aerodynamic principles including the use of propeller (Nishi & Miyagi, 1991) (Nishi & Miyagi, 1994) and recent innovative robots such as vortex climber (Illingworth & Reinfeld, 2003) and City-Climber (Xiao et al, 2005) (Elliott et al, 2007) robots. The vortex climber is based on a so-called "tornado in a cup" technology, while the City-Climber combines the suction and aerodynamic attraction to achieve good balance between strong adhesion force and high mobility.…”
