Extending the spinal orthotic module with a passive self-aligning hip module

A misalignment compensation mechanism for the hip was developed to increase the comfort of the exoskeleton and to hinder movements as little as possible. A purely passive torque source at hip level generates the support needed to unload the lower back.

Passive spinal orthosis with viscoelastic element

Continuus carbon fiber beams which generate support and allow for a large range of motion are used as a back interface. Combined with the torque source at the hip, they generate the torque which reduces the strain on the lower back.

Biomechanical requirements for active version of spinal exoskeleton

We assessed full body kinematics and spine load components in natural lifting, to find kinematic and support pattern requirements for the SPEXOR actuated exoskeleton. Furthermore, using a benchmark actuated exoskeleton, we investigated how specific actuation control modes interact with subject behavior, and how this affects spine loading.
