Cover Story: Robotics exoskeletons have arisen as a cost/effective solution for the increasing demand for rehabilitation services in the private or public health system. In most cases, rehabilitation exoskeletons are designed to follow a specific therapy/treatment, and it is assumed that patients are going to enhance their mobility. However, in neurodegenerative diseases, where patients have lost their mobility, external assistance could improve their life quality. ALICE (Assistive Lower Limb Controlled Exoskeleton) brings a novel concept into robotics rehabilitation. ALICE aims to be an advanced mechanical sensor that allows computing real-time information of both kinetic and kinematic data, opening up a new personalized rehabilitation concept. The ALICE platform includes a robotics wearable exoskeleton and an on-board muscle-driven simulator to estimate the user’s kinetic parameters.View this paper.
