Abstract
A system for control of a prosthetic device includes at least one Inertial Measurement Unit detecting orientation of a user'"'"'s foot. The at least one Inertial Measurement Unit is in communication with a device module configured to command at least one actuator of a prosthetic device. The at least one Inertial Measurement unit sends output signals related to orientation of the user'"'"'s foot to the device module and the device module controls the at least one actuator of the prosthetic device based on the signals from the at least one Inertial Measurement Unit.
