Using Dynamic Rewards to Learn a Fully Holonomic Bipedal Walk

Patrick MacAlpine and Peter Stone

In the AAMAS Adaptive Learning Agents (ALA) Workshop in Valenica, Spain, June 2012.

This page provides details on the optimization of walk parameters for a fully holonomic walk (omnidirectional walk which can walk at the same maximum velocity in all directions). The walk was learned using the goToTarget optimization and the CMA-ES policy search algorithm. Rewards for walking speed in the three cardinal directions of forward, backwards, and sideways were dynamically reweighted from one generation to the next during learning in order to encourage equal walking speeds in all directions.
