In this week's headlines Internet-beaming balloons; battery-free driving on electric roads; an interview with Indy 500 winner Tony Kanaan; and a robot that runs like a cat.
Tech communities are booming all over Africa, says Nairobi-based Juliana Rotich, cofounder of the open-source software Ushahidi. But it remains challenging to get and stay connected in a region with frequent blackouts and spotty Internet hookups. So Rotich and friends developed BRCK, offering resilient connectivity for the developing world.
As a novelist, Daniel Suarez spins dystopian tales of the future. But on the TEDGlobal stage, he talks us through a real-life scenario we all need to know more about: the rise of autonomous robotic weapons of war. Advanced drones, automated weapons and AI-powered intelligence-gathering tools...
This week in WDD’s HotSeat, improved safety at level crossings; tracking motor vibrations through skin in three dimensions; unlocking new applications for telepresence with iRobot’s Ava 500; and a wireless payment system from Audi.
