Abstract

 

It's a tough world for mobile robots: the terrain is rugged, their legs get trapped in crevices, they struggle with poor surface traction, and they wait for human assistance to recover.  How can we study such problems to improve mobile-robot robustness?  This talk presents our approach to mobile-robot error-recovery problems: modeling the available robot freedoms and exploiting the robot's internal dynamics.

We focus on two specific examples: 1) a high-centered legged robot and 2) a wheeled robot stuck in a ditch.  In the high-centered robot problem, we use mechanical-systems theory to analyze a novel locomotion technique called 'legless locomotion': the robot locomotes using the reaction forces produced by swinging its legs.  In the wheeled-robot problem, we use dynamic programming to explore the solution space, since our hand-crafted solutions don't work well.  In future work, we will explore other locomotion errors and search for a common structure.
