Master Thesis: Stable Walking Patterns Through Simplified Models
3. Juli 2012
The principals behind walking and running are up to now far from being completely understood. Simple biological inspired models have been use to capture the key features of human and animal locomotion. The Spring Loaded Inverted Pendulum (SLIP) is probably the most used of such models. It allows generation of stable limit cycles with human-like contact force profiles. While many different approaches have been proposed to design feedback controllers for the SLIP model when it is used to describe running motions, not so many are known for the walking case (bipedal SLIP model).
The goal of this thesis is to summarize the established approaches for control of the SLIP model, extend them to the bipedal SLIP model, find alternative and more suited approaches directly for walking patterns and finally map the results obtained for the simple model to a more complex multi body model based on .
The whole work will be carried out in simulation.
