Cities—whether you love them or hate them, before long most of us will be living in them. By 2008, more than half the world’s population will be urban dwellers. By 2030, 4.9 billion, or 60 percent of us, will call the city home.

This special report focuses on how to solve some of the big engineering challenges we face as the world’s cities multiply, grow, and mature, particularly as they are being played out in the largest and most complicated urban habitats human beings have ever lived in: megacities. In 1950, there were just two cities with populations of 10 million or more: New York–Newark and Tokyo. But by 2015, according to the United Nations, there will be 22 megacities, and 12 of these will have populations of 15 million or more.

Golf Robot Learns To Putt Like A Pro

While being able to drive the ball 300 yards might get the fans excited, a solid putting game is often what separates a golf champion from the journeymen. A robot built by German researchers is quickly becoming a master of this short game using a clever combination of classical control engineering and machine learning.

In golf tournaments, players often scout out the greens the day beforehand to think through how they are going to play their shots, says Annika Junker, a doctoral student at Paderborn University in Germany. So she and her colleagues decided to see if giving a robot similar capabilities could help it to sink a putt from anywhere on the green, without assistance from a human.

These Haptic Microfingers Tickle Pill Bugs’ Toes

Balloon actuators and liquid metal sensors enable tactile human-insect interactions

All things considered, we humans are kind of big, which is very limiting to how we can comfortably interact with the world. The practical effect of this is that we tend to prioritize things that we can see and touch and otherwise directly experience, even if those things are only a small part of the world in which we live. A recent study conservatively estimates that there are 2.5 million ants for every one human on Earth. And that’s just ants. There are probably something like 7 million different species of terrestrial insects, and humans have only even noticed like 10 percent of them. The result of this disconnect is that when (for example) insect populations around the world start to crater, it takes us much longer to first notice, care, and act.

To give the small scale the attention that it deserves, we need a way of interacting with it. In a paper recently published in Scientific Reports, roboticists from Ritsumeikan University in Japan demonstrate a haptic teleoperation system that connects a human hand on one end with microfingers on the other, letting the user feel what it’s like to give a pill bug a tummy rub.
