Tutorial 1: Design in Rehabilitation Robots: a Hand Exoskeleton for Spasticity Assessment
Dr. Hao Yu
Dr. Hao Yu
Hao is post-doctoral research associate at the RAI Lab of Heriot-Watt University. He obtained his PhD at Heriot-Watt University and the University of Edinburgh with a focus on exoskeleton-assisted hand rehabilitation. In his PhD project, he was mainly working on the design and development of a hand exoskeleton for spasticity assessment. Prior to this, He obtained a Bachelor's degree in Mechatronics Engineering from Harbin Institute of Technology and a Master's degree in Human and Biological Robotics from Imperial College London. His research interests lie primarily in rehabilitation robotics, neuromechanics, and musculoskeletal simulation.
Abstract: Traditionally, hand exoskeletons have been designed primarily for functional training or movement assistance, rather than for pathological diagnosis. In many existing designs, the mechatronic development of hand exoskeletons often precedes a clear understanding of clinical needs, resulting in general-purpose devices whose applications are explored only afterward—leaving a gap between the final product and clinical applications. In this presentation, I will introduce a novel hand exoskeleton specifically designed around the clinical need for finger spasticity assessment. I will walk through the entire development process, from clinical need analysis and design specification, to concept development, mechanical design, kinematic and dynamic modelling and simulation, prototype testing, and an initial attempt at integrating digital twin technology.
Tutorial 2: Ergonomic Design of Exoskeletons for Movement Assistance and Rehabilitation
Dr. Emilio Trigili
Emilio Trigili is Assistant Professor at the BioRobotics Institute of Scuola Superiore Sant’Anna (SSSA). He completed his PhD in BioRobotics at SSSA in 2019 and holds an MSc. in Biomedical Engineering from the University of Pisa (Italy). He is actively involved in several European and national projects, leading, supervising and conducting activities related to the design, control and validation of upper- and lower-limb robotic exoskeletons for rehabilitation and assistance, as well as robotic lower-limb prostheses. He is currently the PI of the BioARMnext project, funded by and in collaboration with the Italian National Institute for Insurance against Accidents at Work (INAIL), aimed at developing a portable upper-limb exoskeleton for people with brachial plexus injuries.
Abstract: The design of a wearable robot for movement assistance and rehabilitation poses several challenges for what concerns the physical and cognitive human-robot interaction. In this tutorial talk, the concepts of physical and cognitive human-robot interfaces for wearable robots will be introduced, along with ergonomic design principles of wearable robots for movement assistance and rehabilitation. Safety and ergonomics issues can be addressed via the employment of compliant actuation units, such as series-elastic actuators (SEAs), for their shock-absorption and energy storage capabilities, and via the inclusion of passive degrees of freedom in the robot kinematic chain, in order to allow the self-alignment between the human and robot axes and unload the articulations from undesired forces. On the other hand, smart algorithms and control strategies can be implemented in order to timely detect the user’s intention to move, and adapt the robot action accordingly for a seamless human-robot interaction. Starting from the experience of The Wearable Robotics Lab of Scuola Superiore Sant’Anna, which has a consolidated know-how in the design of rehabilitation and assistive exoskeletons with compliant actuation units (i.e., SEAs), such ergonomics principles will be presented showing examples of their implementation on wearable exoskeletons for the upper- and lower limbs.
Hands-on Session

In this hands-on session, attendees will be guided through a design strategy to create a rehabilitation device tailored to their specific medical needs. The process will start with identifying the target rehabilitation function, followed by progressively translating the clinical requirements into a cohesive integration of technical solutions, and will culminate in a design sketch of a prototype. This design process will take approximately one hour. Afterwards, participants will have the opportunity to try out the hand exoskeleton we have developed for spasticity assessment using this design strategy. They will be able to refine their designs through discussions with the organizers and fellow attendees.

Dr. Michele Francesco Penna
Michele Francesco Penna is a post-doctoral researcher at the Wearable Robotics Lab of Scuola Superiore Sant’Anna (Pisa, Italy), where he obtained his PhD in BioRobotics in 2025. He graduated in industrial engineering with a master’s degree in biomedical engineering from Campus Bio-Medico University of Rome. His research interests include the development, control and validation of upper-limb exoskeletons for rehabilitation and assistance scenarios.
In this hands-on session, we will work on an upper-limb exoskeleton developed by the Wearable Robotics Lab of Scuola Superiore Sant’Anna. The device is a portable elbow exoskeleton, which was designed to be integrated as modular component of an upper-limb portable exoskeleton (shoulder and elbow) for assistance of daily-living in people with brachial plexus injuries or after a stroke. The exoskeleton is capable to monitor torque and position at the elbow level and can be controlled to provide different interaction modalities (from simple gravity compensation to robot-in-charge assistance), to deal with patients with different levels of movement limitations. The device is the result of a user-centered design process, in which different stakeholders, including clinicians and patients, were involved since the initial phase of the design, to identify the clinical needs and the main functional requirements to be translated into technical specifications.
In the hands-on session, participants will be guided in the design and implementation of a simulator that takes as input data from the exoskeleton sensors (elbow joint torque and angle) to verify the implementation of specific control strategies (e.g., gravity compensation) tailored to the target end users. Additionally, they will build a graphical user interface in LabVIEW environment, to visualize graphically the exoskeleton’s sensor data and other real-time processed data, set the control input for the device and save the data. The design of the simulator and the GUI will take into account the main features of the device, specifically considering a target end user population, as well as requirements for a user-friendly interface that can be easily operated by non-technical personnel (e.g., clinicians). At the end of the hands-on session, participants will have the opportunity to try the device, with the possibility of implementing the simulated control strategy on the real hardware.
