How to Keep Drones Flying When a Motor Fails
Robotics researchers at the University of Zurich show how onboard cameras can be used to keep damaged quadcopters in the air and flying stably - even without GPS. As anxious passengers are often reassured, commercial aircrafts can easily continue to fly even if one of the engines stops working. But for drones with four propellers - also known as quadcopters - the failure of one motor is a bigger problem.

Miniscule robots of metal and plastic
Researchers at ETH Zurich have developed a technique for manufacturing micrometre-long machines by interlocking multiple materials in a complex way. Such microrobots will one day revolutionise the field of medicine. Robots so tiny that they can manoeuvre through our blood vessels and deliver medications to certain points in the body - researchers have been pursuing this goal for years.

On the way to lifelike robots
In order for robots to be able to achieve more than simple automated machines in the future, they must not only have their own "brain". Empa researchers postulate that artificial intelligence must be expanded to include the capabilities of a Physical Artificial Intelligence, PAI. This will redefine the field of robotics and the relationship between man and machine.

Drones to monitor ecological changes
A team of researchers from Empa and Imperial College London developed drones that can attach sensors to trees to monitor environmental and ecological changes in forests. Sensors for forest monitoring are already used to track changes in temperature, humidity and light, as well as the movements of animals and insects through their habitats.

Deep Drone Acrobatics
A navigation algorithm developed at the University of Zurich enables drones to learn challenging acrobatic maneuvers. Autonomous quadcopters can be trained using simulations to increase their speed, agility and efficiency, which benefits conventional search and rescue operations. Since the dawn of flight, pilots have used acrobatic maneuvers to test the limits of their airplanes.

This Drone Can Play Dodgeball - And Win
Using a novel type of cameras, researchers from the University of Zurich have demonstrated a flying robot that can detect and avoid fast-moving objects. A step towards drones that can fly faster in harsh environments, accomplishing more in less time. Drones can do many things, but avoiding obstacles is not their strongest suit yet - especially when they move quickly.

Allowing robots to feel
With the help of machine learning, ETH researchers have developed a novel yet low-cost tactile sensor. The sensor measures force distribution at high resolution and with great accuracy, enabling robot arms to grasp sensitive or fragile objects. We humans have no problem picking up fragile or slippery objects with our hands.

A soft robotic insect that survives being flattened by a fly swatter
Researchers at EPFL have developed an ultra-light robotic insect that uses its soft artificial muscles to move at 3 cm per second across different types of terrain. It can be folded or crushed and yet continue to move. Imagine swarms of robotic insects moving around us as they perform various tasks.

On the way to intelligent microrobots
Researchers at the Paul Scherrer Institute PSI and ETH Zurich have developed a micromachine that can perform different actions. First nanomagnets in the components of the microrobots are magnetically programmed and then the various movements are controlled by magnetic fields. Such machines, which are only a few tens of micrometres across, could be used, for example, in the human body to perform small operations.

DeepFly3D: the deep-learning way to design fly-like robots
EPFL scientists have developed a deep-learning based motion-capture software that uses multiple camera views to model the movements of a fly in three dimensions. The ultimate aim is to use this knowledge to design fly-like robots. "Just think about what a fly can do," says Professor Pavan Ramdya, whose lab at EPFL's Brain Mind Institute , with the lab of Professor Pascal Fua at EPFL's Institute for Computer Science, led the study.

"Flying fish" robot can dive and fly
A bio-inspired bot uses water from the environment to create a propelling gas and launch itself from the water's surface. The robot had been developed by researchers at Imperial College London. It can travel 26 meters through the air after take-off and could be used to collect water samples in hazardous and cluttered environments, such as during flooding or when monitoring ocean pollution, report the team lead by Mirko Kovac, who also heads the joint "Materials and Technology Center of Robotics" at Empa, in the latest issue of "Science Robotics".

A miniature stretchable pump for the next generation of soft robots
Scientists at EPFL have developed a tiny pump that could play a big role in the development of autonomous soft robots, lightweight exoskeletons and smart clothing. Flexible, silent and weighing only one gram, it is poised to replace the rigid, noisy and bulky pumps currently used. The scientists' work has just been published in Nature.

The world’s smallest stent
Researchers at ETH Zurich have developed a new method for producing malleable microstructures ' for instance, vascular stents that are 40 times smaller than previously possible. In the future, such stents could be used to help to widen life-threatening constrictions of the urinary tract in foetuses in the womb.

Robot-ants that can jump, communicate and work together
A team of EPFL researchers has developed tiny 10-gram robots that are inspired by ants: they can communicate with each other, assign roles among themselves and complete complex tasks together. These reconfigurable robots are simple in structure, yet they can jump and crawl to explore uneven surfaces.

Robots enable bees and fish to talk to each other
Through an imaginative experiment, researchers were able to get two extremely different animal species located far apart to interact with each other and reach a shared decision with the help of robots. Bees and fish don't often have the occasion to meet, nor would they have much to say to each other if they did.

New foldable drone flies through narrow holes in rescue missions
A research team from the University of Zurich and EPFL have developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters. Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them.

Researchers from EPFL and Stanford have developed small drones that can land and then move objects that are 40 times their weight, with the help of powerful winches, gecko adhesives and microspines. A closed door is just one of many obstacles that no longer pose a barrier to the small flying robots developed jointly by Stanford University and Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland.

New technique reveals limb control in flies - and maybe robots
A new neural recording technique developed by EPFL bioengineers enables for the first time the comprehensive measurement of neural circuits that control limb movement. Tested on the fruit fly, results from the technique may inspire the development of more sophisticated robotic control approaches. One of the major goals of biology, medicine, and robotics is to understand how limbs are controlled by circuits of neurons working together.
