Lower limbs exoskeletons

A lower limbs exoskeleton can help its wearer to move using its own legs. The LSRO is developing several active orthoses, targeted on specific disabilities.

The Hip ball-screw orthosis (HiBSO) is a partial exoskeleton that assists the flexion-extension of the hip joint. It is designed to enable the elderly to walk longer, and help them for the task that require more strength (e.g. standing-up, climbing stairs, etc.).
Its novelty comes from its kinematic, which offers a variable transmission ratio, that depends on the position (maximum torque when sat, high dynamics when walking).

TWIICE is a full mobilization exoskeleton that allows paraplegic people to walk again. The goal of this project is to design a modular exoskeleton, that can fit more people and handicaps. To make it possible, it was designed to be very simple, and cheap to manufacture.
The current prototype of TWIICE allowed Silke Pan to participate to the Cybathlon, the first international competition for para-athletes assisted by robots, on the 8th of October 2016.

Autonomyo is an exoskeleton designed to assist the gait of people with muscular weaknesses, such as myopathy patients, even if they cannot use crutches. It has three actuated degrees of freedom per leg, and is cable-driven.
