Zenta ball hexapod Windoro Window-Cleaning Robot Demo In our best robots of CES roundup last week, it appears that we left out an interesting offering: the Windoro window-cleaning robot from South Korea. That's right. This robot wants to do for your windows what Roomba and Scooba do for your floors. It's quite a sight to see this gizmo magically crawling on glass. But there's no magic, of course. Watch how it works: The mighty iRobot, with its best-selling Roomba vacuums and innovative Scooba floor-washing bots, dominates the cleaning-robot market. Unveiled late last year, the Windoro robot was a joint development between Ilshim and the Pohang Institute of Intelligent Robotics, or PIRO. The Windoro robot can clean windows 6 to 25 millimeters thick (0.2 to 1 inch). One of the robot's two modules works as the navigation unit. The robot first moves up and down and left and right to determine the dimensions of the window. One battery charge lasts about 2 hours, and the robot can clean a surface of up to 12 square meters (130 square feet).

AIST's HRP4: Sci-Fi-Like Household Helper Robots Have Arrived You've seen plenty of robots and androids in the news, but you've probably never seen anything as astonishing as HRP4, which promises to be cheap, powerful, and the most sci-fi-like bot built to date. AIST and Kawada Industries just revealed the new humanoid machine, and by making it look "athletic" they've also turned HRP4 into a real-world version of the fictional life-assisting robots you've seen in countless sci-fi movies (the older generation of 'droids in Will Smith's I, Robot movie for one). He's five feet tall and weighs just 86 pounds, including battery. Bipedal android robotics seems to have evolved swiftly enough that new machines don't need props like Asimo's chunky battery backpack. Nevertheless, HRP4 has 34 degrees of freedom in movement, including full arm articulation and simple hand moves, which give it a grasping force of 1.1 pounds. Check out HRP4 in the video below--it's eight minutes, but worth it. Did you spot the potential here?
Solenoids Basics Introduction to Solenoids / Basics of a Solenoid Two basic laws govern solenoids: Faraday's Law Ampere's Law Faraday's Law The voltage induced in a coil is proportional to the number of turns and rate of change of flux. Ampere's Law The magnetomotive force (mmf) around a closed loop is equal to net current enclosed by the loop. Types of Solenoids There are two main categories of solenoids: Rotary Linear Linear solenoids have applications in appliances, vending machines, door locks, coin changers, circuit breakers, pumps, medical apparatus, automotive transmissions and postal machines to name just a few. Rotary solenoids have applications in machine tools, lasers, photo processing, media storage, medical apparatus, sorters, fire door closures, and postal machines, also just to name a few. Solenoids are used in almost every conceivable industry in the world and are well known as an efficient, affordable and reliable actuation alternative. Force – applies to linear products.

mental_floss Blog » Robot Orders Scone, Leaves Big Tip Today's completely true weirdness: a telepresence robot orders a scone from a coffee shop in Mountain View, California. The robot is given the scone, pays for it, and turns out to be a good tipper. Now, part of what's remarkable about the following video is the whole bit about the robot (which is completely controlled by a person -- that person is visible in a screen on the robot's "face" and speaks with coffee shop patrons and employees via a mic/speaker/camera combo). So we're not talking about autonomous scone-ordering robots just yet. But the more remarkable thing, to me, is how people in the coffee shop react to the robot. This particular video starts a little slowly (as the videographer apparently hears from a friend that a robot is in line, and the videographer dashes to the coffee shop).
Robots: Al.I.S.E Here is my latest robot. Al.I.S.E is an Aluminum, Infrared Scanning Entity; or just an old-school style crank arm hexapod :) This project was based on the mechanicals of the "Hexapod Monster" kit I built and reviewed back in 2008. I scaled it up a little, and added 2 super torquey gear head DC motors I found at a surplus store in Minneapolis. Power comes from a 9.6v RC transmitter pack, along with a separate 9v for the BS2 microcontroller. Motor control is handled by a Solarbotics 1198 CMD driver board kit. I used pencil top erasers for her feet, and found that using scrap pieces of solid core cat5e cable came in really handy for sub-board inter-connects. Paro Therapeutic Robot "Jamming" Robot Gripper Gets Official: Article Published in PNAS Remember that compliant "jamming" end effector unveiled by Colin Angle (iRobot CEO) at TEDMED 2009? Even then, it was demonstrated picking up medication bottles, keys, and water bottles (a hand-held version was also demonstrated). Well, it just got a whole-lot more official with the publication of "Universal robotic gripper based on the jamming of granular material" in the Proceedings of the National Academy of Sciences (PNAS). The cool thing about this method of grasping is its relative simplicity: a rubber sack (balloon) filled with coffee grounds is pressed onto an object, it conforms to the object's natural contours, and the air is pumped out (a volume change less than 0.5%) to form a stable grasp-- no complex grasp planning required. Update on Oct 28th, 2010: John Amend, co-author of the PNAS article, wrote in to share this updated video with voice-over. The latest effort is a joint effort between U. ScienceMag discusses some of the limitations:

Chapit, your new Domestic Robot Today the Raytron company presents a small new robot named Chapit which is an “intelligent” companion helping you for some basic tasks like turning the light on or turning on electric or electronic devices (television… air conditioning system…)one of the biggest advantages of the Chapit is the capacity to recognize a man, woman or child without any programmation. The base model comes with a vocabulary of about 100 words only but it is possible to teach it up to 10.000. It also features an internet connection allowing distant control.
