Understanding the Value of User Feedback in Exoskeleton Design

HeroWear --- UNITED STATES

Exoskeleton developers must pay special attention to the true benefactors of their technology: the user. In this session, Dr. Matthew Yandell, Chief Innovation Officer for HeroWear, will discuss how HeroWear turns user feedback into usable design requirements and implements these requirements into updated features that users actually want. Included will be case studies about Apex exosuit design details that resulted from this process and culminated in the release of the Apex in 2020, and how HeroWear utilizes rapid innovation to pivot to user needs that have been presented and discovered post-launch.

Exoskeleton-based Multimodal Action and Movement Recognition

University of Cincinnati --- UNITED STATES

The talk will present a novel machine learning-based framework that would allow the future of exoskeletons to detect a wide range of actions and movements - walking, walking upstairs, walking downstairs, sitting, standing, lying, stand to sit, sit to stand, sit to lie, lie to sit, stand to lie, and lie to stand, with an accuracy of 82.63%. Thereafter, the talk will also present the optimal machine learning approach for development of such a framework by discussing the findings of a comprehensive comparative study where 17 different machine learning approaches were developed, implemented, and evaluated to deduce the best approach.

Compact upper limb exoskeleton with a hydraulically actuated elbow joint

Johannes Kepler University Linz JKU --- AUSTRIA

A compact, hydraulically actuated upper limb exoskeleton is presented, which supports heavy load lifting in occupational activities. A hydraulic cylinder in combination with an optimized kinematic to reduce the space occupied by the drive system actuates the exoskeleton elbow joint. The presented upper limb exoskeleton is fixed onto a backpack frame structure. The backpack carries the hydraulic supply system and battery. The passive shoulder joint system realizes full three rotary degree of freedom movability centred to the shoulder joint. The wearer of the exoskeleton controls the movement by its muscles; the exoskeleton provides only a supportive force proportionate to an electromyography sensor signal. An electrohydraulic system composed of a speed variable electric motor and a pump creates the force.

Endowing robots with emphatic skills to improve robot-assisted therapy

Department of Neuroscience, Imaging and Clinical Sciences of the University "G. D'Annunzio" Chieti-Pescara --- ITALIA

Recently, there has been a growing interest in the development of social robots to assist children and the elderly with their social needs. However, to be successful in their goal, social robots must be able to empathize with their interlocutors. A great deal of research in the Human-Robot interaction (HRI) area reveals that people sympathize with, and even trust, robots if they recognize their emotional states and react appropriately to them. This research proposes a highly accurate deep-neural-network-based emotion recognition model, efficiently integrated into a robotic platform, and designed to enhance robotic awareness of human emotional state through facial expressions recognition. Further investigation on this course could potentially improve HRI and enable the social robots to become successful tutors.

speakers

Backbone-based back support exoskeleton for working activities

IDSIA USI/SUPSI --- SWITZERLAND

The presentation will introduce a motorized backbone-based exoskeleton for the back support, aiming to assist operators executing working activities. Firstly, the main design concept will be introduced, especially considering the backbone kinematic modeling that is used to design the device. Then, the re-design of the device (introducing additional features, and making it passive) will be described. Finally, preliminary evaluation results will be provided. The exoskeleton is currently under testing within two EUROBENCH phase 2 funded projects: XSPINE and REMOTe_XSPINE. The developed device is a collaboration between IDSIA USI/SUPSI, Politecnico di Milano, and Polibrixia s.r.l.

Exo-H3 integration on SALOEXO Set-up

Technaid, S.L. --- SPAIN

We will speak about the integration of the Exo-H3 in an experimentation infrastructure that include technologies such as emg, optrackers, hololens, IMU or HR. All these will be integrated into ROS, to generate a control interface to obtain real-time information from the different devices and record their information in a synchronized way. Then, according to these recordings, control commands can be given to the exoskeleton to correct or resolve the behavior of the device. This research is carried out within the SALOEXO project that seeks to find the key performance metrics to measure the comfort of the exoskeleton user.

speakers

NUADA: Innovative Hand Function

NUADA --- PORTUGAL

Nuada develops soft and intelligent exoskeletons. The first product is a glove that looks like a normal glove; however, it can hold up to 40 kg of weight with the hand completely relaxed. This product is useful for those who have lack of strength or pain in the hand. These problems can have many causes, such as accidents, disease or old age. Nuada can also be used as an injury prevention or hand rehabilitation system.

speaker

A novel design and control of digital hydraulically driven knee exoskeleton

Johannes Kepler University, Linz --- AUSTRIA

Hydraulically actuated exoskeletons present an attractive alternative (to electrically actuated exoskeletons) due to their high force density, easy energy recuperation, motion locking and damping capabilities. In this presentation, a novel design of digitally driven knee exoskeleton is presented that uses a unique mechanism to satisfy the peak torque requirements during a typical gait cycle with a smaller hydraulic force. The control strategy involves a passive control during the stance phase and a model predictive control during the swing phase. The preliminary results show that the device is successfully able to track the desired knee motion and deliver the required torque.

speakers

Unpowered Exoskeleton for Various Applications

Mawashi Science & Technology --- CANADA

Mawashi's UPLIFT exoskeleton is designed to assist the user during high stress/high fatigue activities that involve lift, move and carry tasks. This innovative exoskeleton intends to increase worker's performance, productivity and endurance when performing logistics tasks. The UPLIFT is designed to assist four main joints with fully unpowered mechanical systems: Knees, Lower back, Shoulders and Elbows. Because of its smart assistance capability, this system also contributes to increase workers'safety and health (reduce risks of developing load carriage related injuries) when lifting and carrying objects by reducing the stresses applied directly on the user's musculoskeletal system.

speaker

Assessment of a lumbar exoskeleton in laboratory conditions

Instituto de Biomecánica de Valencia --- SPAIN

An investigation in the laboratory to assess the impact of the use of the Laevo lumbar exoskeleton in terms of fatigue, free of motion and joint moments was conducted. 10 participants were asked to perform a series of tasks, with and without wearing the exoskeleton. The participants were monitorized with EMG, motion capture, and plantar forces insoles. The EMGs of the muscles gluteus, quadriceps, semitendinosus and spinal erector were measured for the muscle activity analysis. The joint angles motion capture was carried out by measuring the angles of the lumbar, hips, and knees. Also, a biomechanical model was built in order to assess the hip and knees joint moments.

Low-cost 1 degree of freedom ankle exoskeleton for children with Cerebral Palsy

Polytechnique Montréal --- CANADA

Cerebral palsy (CP) is a group of common pediatric neuromuscular disorders (3.1 to 3.6/1000 of children) [1]. This generally results in a pathological gait pattern. Therapies based on the use of exoskeletons on treadmills have shown encouraging results by providing punctual mechanical assistance during the patient's walk [2]. Due to a large market gap, our goal is to develop a low-cost portable and lightweight powered ankle exoskeleton suitable for children. A 3D model was designed was designed and should be able to adapt to a variety of height and weight of the user.
