Robot locomotion can take many forms, from crawling like snakes to rolling like tanks. This one swings like an android ape, using brachiating arm motion to grab onto a surface and forward momentum to keep going.
Concentrating deeply, Cathy Hutchinson stared at the tumbler of coffee on the table in front of her wheelchair. A cup-shaped dome on her head powered her small neural implant, capturing signals from her motor cortex as she thought about holding the mug. Slowly, the robot arm began to move.
Our favorite grippy robot fist, the balloon filled with coffee grounds, has graduated from grabbing to throwing. Its developers at Cornell University and the University of Chicago have taught it how to hurl objects, from mini basketballs to darts.
Dextre, the Canadian robot living idly on the exterior of the International Space Station, will freeload no more. Dextre's first major job as the ISS's man on the outside will demonstrate key technologies that will hopefully lead to future robotic systems that can refuel satellites in orbit, creating a new breed of legacy satellites that don't have to be scrapped simply because their fuel supplies have dwindled.
Exoskeletons aren't all just made for soldiers — now they can help desk jockeys reach for a pen or a cup of coffee, and reduce the fatigue that comes with typing all day long.
The x-Ar arm support won't give you superhuman strength or do your work for you — it will just help your arm feel a little less like dead weight.
The most dextrous, most careful and most useful robotic gripper is not a claw or a hand with several fingers — it's a sack of coffee grounds.
Working with funds from DARPA, researchers at Cornell University, the University of Chicago and iRobot came up with an ideal robotic gripping device, simply a latex party balloon filled with ground coffee. We'll call it the Kinetic Object grippiNg Arm. Cornell would rather call it a "universal gripper," but we think KONA has a nice DARPA-y ring to it.
Armed with better batteries and stronger materials, new submersibles aim to go deeper than ever before and open up the whole of the unexplored ocean to human eyes

The Deep Flight II sub uses stubby wings that propel it down like an airplane goes up.
By liberal estimates, we've explored about 5 percent of the seas, and nearly all of that in the first 1,000 feet. That's the familiar blue part, penetrated by sunlight, home to the colorful reefs and just about every fish you've ever seen. Beyond that is the deep—a pitch-black region that stretches down to roughly 35,800 feet, the bottom of the Marianas Trench. Nearly all the major oceanographic finds made in that region—hydrothermal vents and the rare life-forms that thrive in the extreme temperatures there, sponges that can treat tumors, thousands of new species, the Titanic—have occurred above 15,000 feet, the lower limit of the world's handful of manned submersibles for most of the past 50 years.
Now engineers want to unlock the rest of the sea with a new fleet of manned submersibles. And they don't have to go to the very bottom to do it. In fact, only about 2 percent of the seafloor lies below 20,000 feet, in deep, muddy trenches. If we extend our current reach just 5,000 feet—another mile—it will open about 98 percent of the world's oceans to scientific eyes.

You are dangling like bait at the end of a 22-foot-long robotic arm, and it looks and feels exactly like you're zooming through space. It's tempting to gaze at distant planets, except that an asteroid as big as a house is hurtling toward you. Just before impact, you blast it with a phaser cannon while executing a series of buttery barrel rolls to avoid the debris. The asteroid bits pelt your ship, rattling you to the marrow. Then, without warning, you're sucked through the blackness of a wormholeback into reality.
