For example, the UAV Voliro developed by ETH Zurich is an innovative helicopter that can transform any direction.
Last month, we reported the Omnicopter, developed by the ETH Zurich (ETH Zurich), which has a cube shape that provides thrust for the translation and rotation of all directions. There are many indications that Omnicopter is very convenient to operate. But because of its huge volume, it may only serve in the Swiss Laboratory for a lifetime.
An undergraduate team from ETH Zurich has developed a more flexible UAV Voliro on the basis of the Omnicopter design principle, which can also do azimuth decoupling and state control. The difference is that the Omnicopter has a cubic shape, which leads different directions from the rotor, and the UAV uses a rotating cabin, more useful than the traditional aircraft, and the skill of aerobatics.
Voliro is a key project of ETH Zurich’s autonomous system laboratory. This autonomous system laboratory provides undergraduate students with the opportunity to design a complete system from the end of the last year. It has to be said that this way is very effective. It can enable students who are going to graduate to get practical robot manufacturing experience in laboratory.
Students need to create Voliro from scratch in a short span of 9 months, and the result is amazing.
Compared to the Omnicopter UAV, the Voliro has a more complicated disadvantage, and the overall design provides more freedom in the use of the rotating cabin, but there are more fault points. Control is different from Omnicopter, but they all has the multipurpose potential. They pointed out that over the past few years, other aircraft have been extensively studied. In Omnicopter’s design, the Richard Voyles of the University of the University of the University stressed his 2010 research on the use of inclined components on fully driven helicopters, such as the following video:
In addition to ETH Zurich’s Omnicopter UAVs, the Marx Planck biocybernetics Research Institute also exhibited a “Omnicopter” at the 2013 ICRA meeting, which is just a name coincidence, and the two are different. The latter “Omnicopter” is driven by tilted rotor to achieve similar results.
Lei Feng’s network has learned that Voliro is unique in that it does not only have azimuth decoupling and state control, but ETH Zurich also aims to build it into a “amphibious robot” that can fly, swim, and run on the ground. At present, how to give UAV swimming function is not yet eyebrows, but the Voliro group will develop a lot of improved technology in the future, such as using the three tilt rotor unit as the landing gear, and installing the ball in the Voliro center, so that it can roll on the ground in all directions.
You may feel the engine pod is very familiar, it is because we have seen before in the VertiGo robot. This hybrid electric vehicle can be directly propelling vertically by means of the tilt rotor propulsion, which is impressive. What’s more surprising is that VertiGo is also a key project of research cooperation between independent system laboratory and Disney.
The ideas derived from these focus projects are creative and exciting. We hope that after the end of the research team, do not abandon the research model, if we can keep the integrity of the model, it is the best.
