The Coandă effect is a natural phenomenon, which is that flowing fluid on a certain surface is pulled to the surface due to the viscosity of the fluid. This phenomenon can be utilized to produce the lift force of a flying object. This paper presents a new type of unmanned aerial vehicle (UAV) lifted by the Coandă effect, called SCoandă. We introduce the empirical study of its design and implementations...
Low speed and low energy efficiency are intrinsic issues to be tackled in the study of legged robots. To cope with these problems, this paper presents a bio-inspired design methodology and its implementation on the compliant robotic leg. The proposed robotic leg achieves excellent performances for the high-speed running with low inertia, high energy reusability and large workspace. Moreover, its joint...
In this work, we present a flying saucer, a kind of unmanned aerial vehicle(UAV), lifted based on Coandă effect. Coandă effect is an interesting fluid dynamic phenomenon that the interaction between the flow and curved surfaces produce attraction, which results in the lifting of the object. The flying saucer adopting Coandă effect is easy to hover while keeping its posture stable, and vertical take-off...
