The emerging field of soft robotics, which involves mimicking the squishiness and stickiness of such creatures as octopuses, starfish, and squid, may be taking its next cue from a different source: plants.

Researchers at the University of California at Berkeley describe in the journal Nano Letters a new hydrogel that, inspired by phototropism (the phenomenon of plants moving toward light), can actually expand and shrink in a very controlled fashion via light.

"Shape-changing gels such as ours could have applications for drug delivery and tissue engineering," principal investigator Seung-Wuk Lee, associated professor of bioengineering, said in a school … Read more

In you-knew-that-would-happen news, an adult app store called MiKandi is building apps for Google Glass. A robot refills your beer glass when you're ready for another round. And "Arrested Development" is proving popular, especially with pirates. All that and more on this week's Crave extravanganza. … Read more

When you think of killer robots, you probably imagine Arnold Schwarzenegger running around in a leather jacket and sunglasses, or even ED-209 from "Robocop" causing all kinds of damage. Those sorts of mechanical menaces from film are turning out to be the subject of some real concern in the actual world.

A month ago, Human Rights Watch launched a campaign aimed at stopping killer robots. "Urgent action is needed to preemptively ban lethal robot weapons that would be able to select and attack targets without any human intervention," the organization said in a release.

Now, Christof … Read more

Be afraid. Be very afraid of these three letters: LAR.

Lethal autonomous robots is what Christof Heyns, United Nations special rapporteur on extrajudicial, summary, or arbitrary executions, wants you to think about. He wants a global ban on the development of machines that can target people and kill them without supervision.

"The possible introduction of LARs raises far-reaching concerns about the protection of life during war and peace," Heyns said Thursday during the presentation of his latest report to the U.N. Human Rights Council. "If this is done, machines and not humans will take the decision on who is alive or dies." … Read more

Robot! Fetch me a beer!

Yes, robots can actually carry out that order. Now, they can even anticipate where to pour your beverage of choice.

Cornell University's Personal Robotics Lab has trained a PR2 robot from Willow Garage to figure out where and when to pour beer, as well as perform other actions that require anticipation.

Armed with a Kinect 3D camera and a database of 3D videos, PR2 can analyze what it sees by breaking down activities into several steps. Then it anticipates what might happen next with objects it picks out in the scene. It can choose the most likely next step for activities like eating, drinking, cleaning, and putting things away. … Read more

From personal photographers to aerial artworks, drones are finding new applications every day. Now Germany's national rail network wants to deploy them against graffiti.

Deutsche Bahn says its trains were defaced about 14,000 times in 2012 alone, costing the operator about $9.8 million in cleanup expenses.

The company will start testing drones at large rail depots, where vandalism frequently occurs at night. The drones will be nearly silent and will have GPS tracking and sensitive infrared cameras to establish evidence for criminal prosecution.

The drones will fly at altitudes up to 492 feet with a top speed … Read more

In the wake of the colossal tornado that rampaged through 17 miles of central Oklahoma, plans for storm-chasing UAVs are taking on new significance.

Students at Oklahoma State University have been working on "storm-penetrating air vehicles" that could help cope with deadly tornadoes.

The aircraft are "designed to penetrate thunderstorms, including the supercells that spawn tornadoes" to gather data used to predict storms and warn people about them, the university said in a release. … Read more

If you feel bad about leaving Fluffy home alone, consider giving her the laser treatment.

Petcube is stylish box that lets you play with your pet when you're away. It beams leasers around the room while you control it from afar via smartphone.

Connected to your home Wi-Fi network, Petcube is a 4-inch cube that has a wide-angle camera, microphone, and low-intensity laser pointer.

The prototype is made of glass and aluminum and is being developed by robot enthusiast Alex Neskin, along with Yaroslav Azhnyuk, and Andrey Klen. The Ukranian startup recently showed it off at Seedcamp Week Berlin. … Read more

SAN FRANCISCO--If you don't think a playable Lego electric guitar, complete with the ability to play different notes and adjust pitch, is possible, you don't have enough faith.

Later this year, Lego will launch the third generation of its popular Mindstorms programmable robotics platform. Known as EV3, the third-generation kit will come with plans for 17 different models. But 12 of those models were created by members of an elite, hand-picked, team of Lego community members.

Now, with the eighth-annual Maker Faire hitting the San Francisco Bay Area this weekend, Lego is unveiling three of the 12 community-created … Read more
