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.

If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
Robots in films during the 2000s hit the big time; no longer are they the sidekicks of nerdy character actors. Robots we see on the big screen in recent years include Nicole Kidman, Arnold Schwarzenegger, and Eddie Murphy. Top star of the era, Will Smith, takes a spin as a robot investigator in I, Robot. Robots (or androids or cyborgs) are fully mainstream in the 2000s.
