Sentences with word «quadrotor»

«This is a more energy - efficient and reliable solution since stationary hovering is difficult for quadrotors in the presence of even mild wind — which is common for construction sites.

The compliant wings of a bat - like flapping robot flapping at lower frequencies (7 - 10 Hz vs. 100 - 300 Hz of quadrotors) are inherently safe: because their wings comprise primarily flexible materials and are able to collide with one another, or with obstacles in their environment, with little or no damage.»

In a laboratory experiment, a 50 centimetre by 50 centimetre quadrotor craft equipped with the navigation system was able to take off, travel through an obstacle - filled indoor space and land successfully on an elevated platform.

«The B2 possesses a number of practical advantages over other aerial robots, such as quadrotors,» said Chung.

For example, to get multiple quadrotors to cooperate in building a structure, Mellinger and colleagues designed a loop in 3D space with two destinations and two queues, each with slots where the bots can wait without hitting each another.

He's taken hobbyist quadrotors made by German manufacturer Ascending Technologies and fitted them with custom microcontrollers, open - source software and grippers that allow them to maintain a precise hovering position, and to pick up and manoeuvre small payloads.

Abe Bachrach, a graduate student at the Massachusetts Institute of Technology who has worked with similar quadrotors, though without the aid of external sensors, calls Mellinger's work «impressive».

Advances in software and sensing have given jaw - dropping powers to cheap quadrotor helicopters — ones with four rotors.

Nano quadrotors fly in formation in this great video from the GRASP Lab at the University of Pennsylvania.

A pop - up screen displays the video feed from the EnGuard's onboard quadrotor drone, a DJI Phantom 4.

Images and pre-order information are also locked as well but that's fine since we have a couple of leaked images featuring the new quadrotor.

Furthermore, perching or landing conventional aircraft and quadrotors in such unusual places is nearly impossible, due to their limited control authority at slow motor speeds and aerodynamic couplings such as wall or ground effects.»

Since the B2 does not use high - speed rotors that emit loud, high - frequency noise, it is significantly less intrusive than quadrotors or other aerial robots.

The cameras reveal the position of the quadrotor to within a millimetre and feed the data to a nearby laptop.

Planning software then calculates position - control commands and transmits them to the quadrotor via a wireless link.

A team from the University of California, Berkeley, recently fitted a quadrotor with a Kinect camera, proving the idea could work.

But he says that it may be a while before the quadrotors are truly autonomous.

«Hopefully at some point in the future, we would be able to develop a system that could manoeuvre as aggressively as Daniel's quadrotors have been able to, while doing onboard sensing,» says Bachrach.
