Method of Studying a Process of Turning in an Orthotic Robot

Abstract

This paper analyzes an orthotic robot’s capability of changing the direction of motion as part of its gait process while it is being worn by a user. Exoskeletons and orthotic robots are presented, focusing on their capabilities regarding the implementing a turn of their lower limbs. The devices are analyzed, and a method is proposed, being safe for the user, which ensures the required change of the angular position of the user’s trunk, having performed a turn of the device. The smallest movement of each lower limb, which is necessary to enable a turn of the trunk in such a way that the turn can be performed by both lower limbs, is determined.
