ICYMI: Robots so advanced, they cool themselves with sweat
try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: Researchers from the University of Tokyo devised a better air cooling system for robots that is modeled on their as-yet-overlords, sweaty humans. The 3D-printed bones have spaces for tiny pores, allowing Kengoro to do pushups for 11 minutes without overheating. Next up, world domination.
Brobot can 'sweat' to do push-ups for longer
The Terminator may not feel remorse or pity, but does it even lift, bro? Researchers from the University of Tokyo have developed a robot called Kengoro that can sweat, helping it get through 11 minute push-up sessions that would normally fry the motors. Unlike a normal water-cooled radiator system, liquid flows into porous aluminum bones and then evaporates on the surface to cool the motors, in the same way that sweat cools a human.
ICYMI: Soon flying UAVs could pick stuff up; carry it away
try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: A large format hexacopter with mechanical gripper arms is all set to swoop in on your backyard and move some chairs around. Going by the Prodrone's YouTube video, it can carry 10 kilograms.
ICYMI: Robosurgeon, wigglebot and a very cute penguin
try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: A robot from the Ben-Gurion University of the Negev produces a wave-like motion that can propel itself across a floor or through water, only with one motor. Also a robotic surgeon called Flex can snake its way down throats or other orifices and perform surgeries in a less-invasive way than traditional means. But you should probably take in Purps the penguin and her 3D-printed boot, and also the robotic massager we all wish we had. As always, please share any interesting tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.
These LED bulbs are brighter despite fewer diodes and a lower price
One of the toughest parts to swallow of LED lighting technology is just how costly it can be. Well, the folks at Cree have taken umbrage with that and developed a bulb that'll retail for around $5 per 40- and 60-watt-equivalent bulb -- less than some standard CFL lamps by a few bucks. How's it doing that? In part by changing the bulbs' design and eliminating the need for heat sinks. As IEEE Spectrum reports, instead of the collar that more or less does double-duty holding the LEDs in place and dissipating heat, the new models get rid of hot air via convection. Meaning, as diodes get warmer, they naturally draw cool air in from outside the bulb as the higher temperature rises upward and outward.
Visualized: a look inside iRobot's gadget-filled 'cool stuff room' (video)
We've all seen a Roomba at one point or another, be it picking up debris around our feet in a friend's living room or chauffeuring a courageous kitty for an entertaining clip on YouTube. Likely far less familiar, however, is iRobot's gadget-filled Massachusetts headquarters, including the museum-like "cool stuff room" in the lobby. There you'll find a large variety of autonomous devices, ranging from an early Roomba prototype that subs in a removable cloth for the vacuum to the relatively creepy My Real Baby -- an $89 doll that cries for food and offers realistic reactions to tickling. There's also plenty of industrial and military gear on hand, including a long cylindrical bot used for repairing oil rigs as they continue to operate, a full-size self-driving vehicle and a wall-climbing robot that uses suction cup wheels to ascend vertically. Some of the exhibits are downright creepy, such as a crab-like prototype which an iRobot employee referenced as being "inspired by nature," though the company's familiar household gadgets help to balance out the eerie. Sadly, the collection doesn't appear to be open to the public, though IEEE was granted a tour, which it graciously filmed for your enjoyment -- you'll find that video walkthrough just past the break.
Fukushima technician gives behind-the-scenes look at the cleanup operation
New details about the robotics deployed to help clean up Japan's Fukushima nuclear plant have emerged, thanks to a series of blog posts penned by an anonymous technician. Known only as 'S.H.', the blogger wrote of the effectiveness of the donated iRobot Packbots and Warriors (despite their prolonged exposure to electronics-damaging radiation), while criticizing the Tokyo Electric Power Company for what he saw as inept supervision, unreasonable schedules and disregard for technician safety. S.H., who helped retrofit a vacuum cleaner onto a robot to collect radioactive dust, also revealed technical details about the robots, explaining that they were manipulated with a PlayStation-style controller via a Panasonic Toughbook and that the devices were most effective in pairs, which allowed for better wireless connectivity and faster emergency response. The site was taken down after it began circulating on Twitter but IEEE kept and translated the posts, available for your perusal at the source link, below.
