A better understanding of how actuator design supports locomotor function may
help design and develop novel and more functional powered assistive or robotic legged
systems. Legged locomotion can be described as a composition of locomotor
sub-functions, | A better understanding of how actuator design supports locomotor function may

- | In this
project, we focus on the axial leg function (e.g., spring-like hopping) based on a novel concept of a hybrid electric-pneumatic actuator (EPA). This principal locomotor sub-function determines
the movement of the body center of mass. We will design and manufacture EPA prototypes
as enhanced variable impedance actuators (VIA). In contrast to other VIAs, the EPA provides not only adaptable compliance (e.g. an adjustable spring)
but with the pneumatic artificial muscle (PAM) also
an additional powerful actuator with muscle-like properties, which can be
arranged in different configurations (e.g., in series or parallel) to the electric motor (EM). This novel hybrid actuator
shares the advantages of EM and PAM combining precise control with compliant
energy storage required for efficient, robust and versatile human-like leg motions via simple control
laws. | + | In this
