The video shows stable hover of a novel Vertical Take-Off and Landing (VTOL) aircraft — the Cyclocopter, developed at the University of Maryland by Dr. Moble Benedict, Mr. Joseph Mullins, Dr. Vikram Hrishikeshavan and Prof. Inderjit Chopra.
Cyclocopter utilizes cycloidal-rotors (cyclorotors), a revolutionary horizontal axis propulsion concept which has many advantages such as higher aerodynamic efficiency and maneuverability. One of the key advantages of the cyclorotor is its thrust vectoring capability, which is utilized in the present study for yaw control. The present vehicle has a quad-cyclorotor configuration where each of the rotors is powered using independent motors. Also by using separate thrust vectoring mechanisms for each rotor, each of the thrust vectors could be independently tilted making the vehicle extremely maneuverable.
The cyclorotor design was optimized based on the detailed experimental studies conducted by Dr. Moble Benedict, Mr. Tejaswi Jarugumilli and Prof. Inderjit Chopra. A novel attitude control technique is developed using differential RPM control and thrust vectoring which is also designed to take care of the inherent pitch-roll couplings. For closed-loop attitude stabilization of the vehicle, a proportional-derivative controller was implemented on an onboard 3 gram processor-sensor board. Using this control system, the stable autonomous hover of the cyclocopter was successfully demonstrated. This is the first pure cyclocopter (entire thrust produced from cyclorotors) in the history to perform stable controlled hover after the inception of this concept 100 years back.

New media art duo SWEATSHOPPE aka Blake Shaw and Bruno Levy are back from Europe with a new video that showcases their live interactive video wheatpaste in Berlin, Bristol, Belgrade, London and Paris. Over a two week period the duo pasted their videos in over 10 spots including the Berlin Wall, Les Invalides, Cordy House and even constructed a 5 meter telescopic electronic paint roller to create a two-story tall video painting in Bristol.
Video painting is a technology the duo developed that allows them to create the illusion that they are painting videos onto walls with electronic paint rollers they built. It works through custom software that they wrote that tracks the position of the paint rollers and projects video wherever they choose to paint, allowing them to explore the relationship between video, mark making and architecture and create live video collages in real time.
