This work proposes a new swing controller for semi-powered low impedance transfemoral prostheses that resolves the issue of potentially competing inputs between artificial assistive power and user-sourced power. Rather than add power as an exogeneous input, the control approach uses power to modify the homogeneous portion of the shank dynamics, and...

Over the last decade, the automotive industry has faced several challenges to reduce vehicle's emissions, moving towards more efficient wheeled transportation. Among all, automotive suspension systems are becoming key players in reducing the carbon footprint of vehicles. In this context, regenerative shock absorbers (RSAs) have been employed to rec...

Recent human-centred design studies suggest that acoustic noise could affect the physical use and psychological acceptance of a biomedical device. These aspects are especially relevant in the prosthetic field, in which device loudness is often related to rejection. The aim of the study is to inquire on the possibility to reduce the acoustic noise e...

In the following research work, an experiment of guided innovation is presented. The context is the Innovation for Change (I4C) program, in which we, a group of students, either PhDs or MBAs, are asked to solve a challenge provided by a stakeholder. The problem is "the future of work" in the context of a post pandemic scenario, with a focus on how...

This work proposes a systematic methodology for designing an active leveling system (ALS) actuator for lunar landing application. The ALS actuator is integrated into an inverted tripod leg layout, exploiting a honeycomb crushable damper as a shock absorber. The proposed ALS actuator is fitted within the leg’s primary strut and features a custom per...

In mechatronic applications such as electro-hydrostatic actuators, gerotor machines are often preferred over other technologies due to their high efficiency, low wear, low noise, and compactness. The design approach for hydraulic machines, either for motoring or pumping applications, involves the definition of different geometrical parameters, whic...

Non-destructive evaluation (NDE) has become a reliable inspection tool to detect structural flaws in many engineering domains. Similarly, advancements in computer-vision made it possible to assess structural conditions from a set of digital images. This research introduces a novel inspection technique for detecting subsurface defects that cause hea...
