Aerone’s super-sized drone appears to have come a long way since we last saw it lifting a skydiver high into the air for a jump almost a year ago.

The Latvia-based drone developer has been busy refining the design and equipping the flying machine with various tools that allow it to perform a variety of tasks.

The European Space Agency (ESA) has successfully tested a prototype ion engine powered by air that could provide propulsion for orbiting satellites almost indefinitely, and could even help power future missions to Mars.

You’re probably familiar with those regular old light switches that you fumble for in the dark, but maybe you’re unclear on what a smart switch is. Good news: you’ve come to the right place.

In order for bipedal robots to live up to their potential usefulness, it’s important that they can navigate on a variety of different surfaces and deal with whatever potential obstacle is thrown their way. That’s something that researchers from China’s Guangdong University of Technology’s School of Automation have been working on with a new self-balancing robot called Jet-HR1.

A new robotic tool could help rescue workers locate victims of disasters and other emergencies before venturing into collapsed buildings or other potentially dangerous places.
