Abstract
In recent years, various kinds of small flying or hovering robots have been developed at various research institutions. The robots are expected to be used for observing the places where humans cannot enter, and any security cameras are not placed. However, it is difficult to keep robots hovering in the air for a long time because power loads of motors are heavy and battery capacities are limited. For this reason, a hovering robot stickable to a wall over 24 hours without supplying powers to main rotors was investigated here. By developing a new sucker with a soft surface ring of thermoplastic styrene elastomer and new mechanisms for dealing with pitching and yawing, a robot surely stickable to a wall was successfully fabricated.
