Advanced mathematical techniques enable better AUV navigation

November 8, 2011 3:42 am | by Nancy Stauffer, MIT Energy Initiative | News | Comments

Since the 1970s, when early autonomous underwater vehicles (AUVs) were developed at the Massachusetts Institute of Technology, scientists there have tackled various barriers to the design of robots that can travel autonomously in the deep ocean. Part two of the four-part series examines how advanced mathematical techniques enable AUVs to survey large, complex, and cluttered seascapes.

Father of artificial intelligence dies in California

October 26, 2011 10:28 am | News | Comments

John McCarthy, a pioneer in artificial intelligence technology and creator of the computer programming language often used in that field, died this week at age 84. He was a leader in the field, coining the term in a 1955 research proposal and going on to create influential laboratories at both Stanford University and Massachusetts Institute of Technology.

Robot biologist solves complex problem from scratch

October 14, 2011 5:16 am | News | Comments

First it was chess. Then it was Jeopardy. Now computers are at it again, but this time they are trying to automate the scientific process itself. An interdisciplinary team of scientists at Vanderbilt University, Cornell University, and CFD Research Corporation Inc., has taken a major step toward this goal by demonstrating that a computer can analyze raw experimental data from a biological system and derive the basic mathematical equations that describe the way the system operates.

Honing household helpers

May 26, 2011 5:55 am | by Emily Finn, MIT News Office | News | Comments

Imagine a robot able to retrieve a pile of laundry from the back of a cluttered closet, deliver it to a washing machine, start the cycle, and then zip off to the kitchen to start preparing dinner. This may have been a domestic dream a half-century ago, when the fields of robotics and artificial intelligence first captured public imagination. However, it quickly became clear that even "simple" human actions are extremely difficult to replicate in robots. Now, MIT computer scientists are tackling the problem with a hierarchical, progressive algorithm that has the potential to greatly reduce the computational cost associated with performing complex actions.
