Wed, 10/13 7:00 pm HMC’s Galileo Auditorium
On Robots, Probability, and Artificial Intelligence
This talk will expose the audience to recent developments in real-world robotics. The speaker and his team have developed mobile robots that have operated as interactive tour-guides in a Smithsonian museum, assisted elderly people in everyday tasks, and explored several abandoned coal mines inaccessible to people, all completely autonomously. His current effort aims at winning the DARPA Grand Challenge, which requires the development of a ground vehicle that can drive from L.A. to Las Vegas without human assistance. These developments would not have been possible without a new paradigm in robot software design, known as probabilistic robotics. Probabilistic robotics imports concepts from statistics and decision theory into the field of robotics. As part of this presentation, the speaker will introduce the audience to the basics of probabilistic robotics, and explain why statistical techniques have become such an essential tool in robotics, in such a remarkably short time.

Top-down program design
Given: a description of the problem
1. Visualize what the program will do -- the more detail, the better
2. Break the work required into a set of smaller tasks.
3. Sketch out these tasks (in a file or on paper)
- If so, write ( and test ) a method that does the job.
Wanted: a program that solves it
• Do any of the pieces you need occur often ?
• What do you need: variables, if/switch, for/while loops?

except
