Investigating Compounding Prediction Errors in Learned Dynamics Models

no code implementations17 Mar 2022 Nathan Lambert, Kristofer Pister, Roberto Calandra

In this paper, we explore the effects of subcomponents of a control problem on long term prediction error: including choosing a system, collecting data, and training a model.

Nonholonomic Yaw Control of an Underactuated Flying Robot with Model-based Reinforcement Learning

no code implementations2 Sep 2020 Nathan Lambert, Craig Schindler, Daniel Drew, Kristofer Pister

As a comparison to the significant engineering effort required for an analytic control law, we implement a data-driven model-based reinforcement learning yaw controller in a simulated flight task.

Data-efficient Learning of Morphology and Controller for a Microrobot

1 code implementation3 May 2019 Thomas Liao, Grant Wang, Brian Yang, Rene Lee, Kristofer Pister, Sergey Levine, Roberto Calandra

Robot design is often a slow and difficult process requiring the iterative construction and testing of prototypes, with the goal of sequentially optimizing the design.

Learning Flexible and Reusable Locomotion Primitives for a Microrobot

no code implementations1 Mar 2018 Brian Yang, Grant Wang, Roberto Calandra, Daniel Contreras, Sergey Levine, Kristofer Pister

This approach formalizes locomotion as a contextual policy search task to collect data, and subsequently uses that data to learn multi-objective locomotion primitives that can be used for planning.
