Combining neural networks and tree search for task and motion planning in challenging environments

IROS 2017poster

Task and motion planning subject to Linear Temporal Logic (LTL) specifications in complex, dynamic environments requires efficient exploration of many possible future worlds. Model-free reinforcement learning has proven successful in a number of challenging tasks, but shows poor performance on tasks…

Sampling-based synthesis of maximally-satisfying controllers for temporal logic specifications

IROS 2017poster

Sampling-based methods have advanced the state of the art in robotic motion planning and control across complex, high-dimensional domains. With few exceptions, such approaches only admit simple constraints and objectives, such as collision-avoidance and reaching a goal state. In this work we leverag…

Dynamics-driven adaptive abstraction for reactive high-level mission and motion planning

ICRA 2015poster

We present a new framework for reactive synthesis that considers the dynamics of the robot when synthesizing correct-by-construction controllers for nonlinear systems. Many high-level synthesis approaches employ discrete abstractions to reason about the dynamics of the continuous system in a simplif…

Online horizon selection in receding horizon temporal logic planning

IROS 2015poster

Temporal logics have proven effective for correct-by-construction synthesis of controllers for a wide range of robotic applications. Receding horizon frameworks mitigate the computational intractability of reactive synthesis for temporal logic, but have thus far been limited by pursuing a single seq…
