Crazyswarm: a large nano-quadcopter swarm
(0) | 24/05/2017 | Translate: Crazyswarm is a swarm of 49 Crazyflie 2.0 nano-quadcopters operating in a new experimental robotics building at USC.
We localize the quadcopters with a Vicon motion-capture system and a custom object tracker that supports identical marker arrangements. Three shared radios broadcast position updates at 100Hz and send high-level trajectory commands to each vehicle. Vicon-IMU sensor fusion, trajectory evaluation, and position control are all performed onboard at 500Hz.
The rotating pyramid demo is built from ellipse commands. The USC letters demo is built from point-to-point commands with each vehicle planning fifth-order polynomial trajectories onboard. A Python scripting layer controls the overall sequence of events.
A forthcoming publication from our group will describe the components of this system, the platform constraints, tradeoffs, and the associated design decisions in detail.
Man built a swimming pool in the shape of a pirate ship for his children, but the neighbors forced it to be demolished It took Toronto resident John Konstantinidis eight weeks to build a swimming pool on the property of his suburban home. The man wanted his children to have more fun during the lockdown during the coronavirus pandemic. However, an unusual object in the form of a pirate ship had to be demolished after complaints from neighbors. Just a week after the completion of the work, Konstantinides was approached by representatives of local authorities with an order to dismantle the facility. As it turned out, they received an appeal from one of the man's neighbors, according to whom, the pool was built too close to the border of the site and the fence standing there. The municipality agreed with the complaint, pointing out to Konstantinidis that the construction of pools requires a special permit. In addition, for an object of this size, it is also necessary to draw up a special document regulating building codes and regulations. According to the father, the news of the demolition of the pirate ship was extremely upsetting for his two children. He was outraged by the attitude of the neighbors and claims that they could first express their grievances in a personal conversation. Nevertheless, the man dismantled the pool, received all the necessary documentation and built it again in accordance with all the requirements of the authorities. So in the end the story ended well.- Converting a Russian UAZ van into a “house on wheels” Building a mobile home on an UAZ platform

- First Interstellar Asteroid Wows Scientists Scientists were surprised and delighted to detect --for the first time-- an interstellar asteroid passing through our solar system. Additional observations brought more surprises: the object is cigar-shaped with a somewhat reddish hue. The asteroid, named ‘Oumuamua by its discoverers, is up to one-quarter mile (400 meters) long and highly-elongated—perhaps 10 times as long as it is wide. That is unlike any asteroid or comet observed in our solar system to date, and may provide new clues into how other solar systems formed.

- Phase-Functioned Neural Networks for Character Control We present a real-time character control mechanism using a novel neural network architecture called a Phase-Functioned Neural Network. In this network structure, the weights are computed via a cyclic function which uses the phase as an input. Along with the phase, our system takes as input user controls, the previous state of the character, the geometry of the scene, and automatically produces high quality motions that achieve the desired user control. The entire network is trained in an end-to-end fashion on a large dataset composed of locomotion such as walking, running, jumping, and climbing movements fitted into virtual environments. Our system can therefore automatically produce motions where the character adapts to different geometric environments such as walking and running over rough terrain, climbing over large rocks, jumping over obstacles, and crouching under low ceilings. Our network architecture produces higher quality results than time-series autoregressive models such as LSTMs as it deals explicitly with the latent variable of motion relating to the phase. Once trained, our system is also extremely fast and compact, requiring only milliseconds of execution time and a few megabytes of memory, even when trained on gigabytes of motion data. Our work is most appropriate for controlling characters in interactive scenes such as computer games and virtual reality systems.
- NVIDIA AI Car Demonstration In contrast to the usual approach to operating self-driving cars, we did not program any explicit object detection, mapping, path planning or control components into this car. Instead, the car learns on its own to create all necessary internal representations necessary to steer, simply by observing human drivers. The car successfully navigates the construction site while freeing us from creating specialized detectors for cones or other objects present at the site. Similarly, the car can drive on the road that is overgrown with grass and bushes without the need to create a vegetation detection system. All it takes is about twenty example runs driven by humans at different times of the day. Learning to drive in these complex environments demonstrates new capabilities of deep neural networks. The car also learns to generalize its driving behavior. This video includes a clip that shows a car that was trained only on California roads successfully driving itself in New Jersey .

- Mercedes Future Truck 2025 (Autonomous Driving Demo) The Mercedes-Benz Future Truck 2025 constitutes a revolution in efficiency, safety and networking, a revolution for road traffic and its infrastructure, for professional driving and for the road transport sector. This is not a new truck, but rather the key element in the interconnected transport system of the future. It is being developed as part of the "Shaping Future Transportation" initiative by Daimler Trucks to conserve resources and reduce emissions of all kinds. Other aims are to ensure the highest possible level of traffic safety and to boost networking with intelligent data management considerably for tailor-made vehicle and service solutions.
The prototype demonstrated the exciting capabilities of the Future Truck 2025 back in the summer at speeds of up to 80 km/h in realistic traffic situations on a section of the A14 motorway in Magdeburg, Germany. Now the thrilling exterior and interior of that same vehicle are being revealed.
