Motivation
Motivation
Humans decide current step based on the prediction of future steps
Likewise, humanoids and quadruped robots require prediction of the future for multi-contact locomotion
Problem Statements: High-dimensional space (poor real-time performance) and complex dynamics (instability of controller)
