Since they conquered the task of programming "observer" robots to track "target" robots, Stanford computer scientists are tackling the more difficult problem of getting their observers to stalk robots on the move. The autonomous observer does more than follow its target around at a discreet distance. The spy robot continuously calculates where it needs to be to ensure that the target doesn't disappear behind a column or down a hallway. The robot measures distances to walls and furniture with a horizontal laser range sensor and uses this information to create a two-dimensional floor plan. A built-in horizontal video camera creates a series of overlapping three-dimensional views of the space. The robot combines this information into a 3D rendering of the area. The robot has a second camera focused on the ceiling to help it track its position. The target robot doesn't stand a chance of blending in, with a black-and-white pattern stenciled on every side. In an associated project with Professor Ruzena Bajcsy's group at the University of Pennsylvania, Chairman of Stanford's Computer Science Department, Jean-Claude Latombe and his students are developing an observer robot that can identify and track unmarked robots and people. The 4-ft tall spies are built by Nomadic Technologies (Mountain View, CA) resemble an upright tank vacuum cleaner without the hose. An additional grant from the Army will give the researchers four more robots. These smaller additions will allow the researchers to devise methods for deploying multiple observers.

Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
