Background & Goal
The goal of BALANCE is to realize a robotic exoskeleton that improves the balance performance of humans while standing and walking. Such a robot could help in situations where keeping balance is difficult, such as in specific work conditions, or help people that have difficulty maintaining their balance, such as people with neurological injury, for example during rehabilitation sessions.
The exoskeleton will be human-cooperative. This means that it will support the user, but not fully take over the control when this is not needed. Depending on the application it can either assist only in difficult conditions or in case of erroneous behavior of the user, or it can fully take over postural balance control. Supported tasks are functional standing and walking, in a clinical, real all-day life or work environment.
Our main task in the project is to identify human balance control and understand how this seemingly simple task works. There are two main approaches to this: balance experiments in healthy human subjects and modeling of balance control. The former focuses on measuring the kinetics and kinematics of subjects during balance-challenging experiments, and extracting balance strategies from them. The latter can be used to validate strategies and test balance controllers in a simulation environment. An example experiment is walking with a reduced base of support by using custom-built orthoses. Used models vary from simple inverted pendulum models to more complex multibody systems.
