• Autonomous Robotics: Estimation and Nonlinear Dynamics

  Christopher Heckman

  Time: 12:00 PM

  In this talk, I will discuss algorithms that are addressing critical challenges to robot autonomy: visual-inertial perception with online statistical change detection and drift correction, and adaptive simulation-in-the-loop model predictive control (MPC). Visual-inertial simultaneous localization and mapping (SLAM) is a technique used to navigate in unknown environments; we have augmented it with the ability to both self-calibrate and correct for calibration drift over time. Our method relies on determining when calibrations have become stale and initiates a new self-calibration when they do, applying calibrations post-hoc for higher accuracy. Nonlinear MPC on the other hand focuses on how to infer optimal control inputs of a high-dimensional nonlinear plant model. I will show how these methods apply to autonomous vehicles moving at fast speeds, and how they extend to novel maneuvers such as jumping and slipping on real platforms.

• Structural Properties of Substitution Minimal Systems

  Andrew Dykstra

  Hamilton College

  Time: 12:00 PM

  View Abstract

  Iterating a substitution rule is a simple way to generate a symbolic dynamical system, and with modest assumptions about the substitution rule, the system it generates will enjoy nice structural properties. In this talk we will look at examples of substitution systems, as well as how structural properties of a given substitution system are preserved under topological conjugacy.
