EMPOWER reimagines human-machine synergy by empowering machines with advanced intelligence and humans with augmented physical strength. Through the integration of real-time AI into active exoskeletons, EMPOWER creates a human-machine system where human expertise and decision making directs exoskeleton support to optimally augment human physical strength. Multi-modal, multi-sensor perception enables the prediction of workflows, the understanding of complex tasks, and the proactive adjustment of exoskeleton support characteristics. We will present work-in-progress results on multi-modal activity recognition for exoskeleton control. EMPOWER will demonstrate its innovations in industrial environments such as steel processing, logistics and construction, where prototypes with showcase how adaptive body-worn exoskeletons can reduce physical strain, mitigate the risk of musculoskeletal disorders, and preserve human-centered decision-making in demanding work settings.

At the research group Mobilab&Care, we collaborate with the healthcare industry to implement digital design workflows and 3D-printing techniques for the production of customized assistive devices, including orthotics, prosthetics, exoskeleton interfaces, and occupational therapy aids. We present a parametric design approach using Rhino 3D and Grasshopper algorithms to create devices based on 3D scans and anatomical landmarks, enabling optimal fit, improved alignment, and reduced production time. The method supports design flexibility and integration of mechanical components. To address durability concerns, we developed custom mechanical testing protocols, as existing standards are limited for evaluating patient-specific, additively manufactured devices

Manual labor is still strongly present in industrial contexts. this commonly involves tasks requiring working in non-ergonomic conditions and manipulating heavy parts, which can lead to musculoskeletal disorders. the back is one of the most affected regions. the eit-m superhuman project aims to industrialize, test, validate, and assess a hip-low back exoskeleton for labor applications, assisting the workers. the consortium integrates the supsi back-support exoskeleton and the gogoa hip exoskeleton. ctag provides expertise in laboratory tests, and art-er assists the consortium in engaging industrial partners for testing purposes. bonfiglioli riduttori and mch sonae are the two end users testing the proposed solution. in this presentation, we will provide the audience with the design and evaluation strategies adopted in the project.

The presentation focuses on reducing the mass of the rehabilitation exoskeleton of an upper extremity targeted at convenient home use with the possibility of assembling the device to the objects of daily use (such as chairs or beds). the presented investigation included a hybrid approach to finite element model topology and parametric optimisation for additively manufactured objects. it elaborates on the different methods of constructing driving systems and passive joints to enable high-stress resistance and stiffness while not increasing mass and providing full mobility of shoulder and elbow joints - critical for the task-oriented treatment. the design process is based on the real-life registered activities of daily life and multibody dynamics computations of the simulated exoskeleton with different extremity models. the works were held within a research project funded by the national center for research and development (lider xiv, contract number lider14/0196/2023).

We will discusses a novel approach in 3D movement analysis in humans (and non-rigid exoskeletons/robotics). Custom ‘UMIMU sensors’ were developed, each comprising a fully-integrated pair of Magnetic Inertial Measurement Unit (MIMU) and UIWB sensors, with an timing-optimizied embedded protocol measuring all distances within an UMIMU swarm. EKF-based position-estimating methods were developed/validated for achieving the accuracy and reproducibility required for improved 3D movement analysis. A study into ranging errors in typical gait analysis conditions were studied. Their mitigating is subject of current research. Also a novel segment calibration method is discussed that merges the worlds of marker-based and MIMU-based movement analysis, facilitating e.g. MIMU-based gait analysis in patients that cannot perform the standard pose/squat tasks required in current MIMU-based gait analysis.

Nonverbal communication plays a crucial role in social interactions, yet visually impaired individuals face significant challenges in perceiving these cues. This talk explores the development of a haptic glove designed to convey emotional and contextual information through vibrotactile feedback. Based on qualitative research and user studies, we examine which information should be transmitted and how emotions can be effectively perceived haptically. The talk will discuss findings from user interviews, prototype development, and initial evaluations, highlighting the potential of haptic technology to enhance accessibility and social inclusion. By bridging the gap between technology and human interaction, this research aims to create more intuitive and meaningful communication experiences for visually impaired users.

Lymphedema, caused by congenital malformations or secondary injuries from cancer treatments, results in lymph accumulation and tissue swelling. Affecting over 250 million people worldwide, it predominantly impacts adult women. This work presents an advanced healthcare solution leveraging soft robotic actuation to enhance lymphedema therapy. The device, designed as a textile sleeve, integrates pneumatic actuators with inflatable polymeric bladders, enabling dynamic pressure adjustments that replicate certified manual lymphatic drainage techniques. Focused on treating the upper arm, forearm, and hand, this innovation prioritizes effectiveness, user safety, and comfort. By automating therapy with biomimetic pressure patterns, it offers a high-performance, non-invasive alternative for improved patient outcomes.

FleXo is a lightweight, flexible, passive back-support exoskeleton designed to reduce lower back strain during lifting tasks while allowing complete freedom of movement for activities like walking or sitting. FleXo's mechanical structure is based on a chain of patented Modular Assistive Vertebrae whose dimension and location are the outcome of a multi-objective design optimization strategy, emphasizing both functionality and user comfort by simultaneously balancing the reduction of lower back strain, the preservation of the user's range of motion, and weight and ergonomics of the device. FleXo's design has been validated through lifting experiments, with particular attention to the subjects' feedback, which is used to inform the design of subsequent versions, ensuring continuous improvement and practical efficacy in reducing lower-back strain.

This study aims to develop a hybrid FES-exoskeleton system to enhance neurorehabilitation for lower limb mobility. By incorporating a biomechanical model of the lower limbs, including joint stiffness, the research examines motion dynamics and muscle activation patterns to enable seamless integration of functional electrical stimulation (FES) and exoskeleton support. The system features adaptable control designs tailored to individual users, ensuring a more personalized approach to rehabilitation. Additionally, real-time electromyography (EMG) signals are utilized as feedback to improve the interaction between the user and the system, fostering more efficient and natural movement patterns.

Industrial exoskeletons are gaining acceptance in workplaces to reduce work-related musculoskeletal disorders (WMSDs). Because workers perform diverse tasks, exoskeletons must be versatile. Active exoskeletons offer greater adaptability than passive exoskeletons, allowing for adjusting force assistance based on user activity. A key challenge is to determine the amount of control users should have while ensuring safety and functionality. Advances in virtual augmented and mixed reality can enhance user interaction. This talk presents a VR-based user interface for occupational exoskeletons. The system allows users to manage key functions such as calibration, adjustment, activation, and force modulation. It can automatically adapt force assistance when users handle loads, thereby improving both efficiency and usability.
