Special Issue Information

Dear Colleagues,

Assistive robots represent a fundamental technology designed to enhance the quality of life for individuals with various conditions, including mobility and neurological diseases, among others. The adoption and widespread use of these robots are influenced by public perception of new technologies and the reliability and robustness of these systems.

Extensive research has focused on advancing this technology to broaden the range of tasks that can be performed with robotic assistance. In fact, the integration of assistive robots into everyday life has the potential to improve the quality of life for all individuals, not just those with specific conditions. However, for this integration to be successful, significant advancements in robot behavior and interaction are essential.

This Special Issue will concentrate on enhancing the reliability of assistive robotics and improving human–robot interactions. We invite scientists to submit their exceptional work addressing these topics, including but not limited to the following areas:

  • The design, modeling, and control of assistive robots;
  • Human–robot interaction;
  • Reliability of robots;
  • Robotic manipulators;
  • Rehabilitation robots;
  • Social assistive robotics.

We look forward to your contributions and to advancing the field of assistive robotics together.

Most exoskeletons designed to assist users in load-bearing tasks face a mechanical dilemma in their conception. Designers may find a compromise between stiff active actuators-based architectures which are powerful but bulky and compliant actuator-based designs which are much less assistive but less constraining for users. This article presents a new open-source simulation-based design tool and a human-centered method that lets orthosis designers explore different device configurations and evaluate some performance criteria. This framework was applied in three different young-adult subjects. The effects of design personalization on user morphology and gait were studied. First, an ankle–foot orthosis designed to support a 20 kg backpack was defined according to the user’s height, weight, and walking speed. Then, a simulation of the subjects fitted with their customized design walking at a self-selected speed on flat ground carrying this additional load was performed. First, the results showed that the designed method inspired by natural joint stiffness behavior provided viable personalized mechanisms. Second, significant reductions in peak joint torque and mean joint activity were observed when comparing muscle-generated torques while the subject was wearing the 20 kg backpack with ankle–foot orthoses on both legs or without. Finally, it shows the value of an open-access tool for exploring the coupling of passive and active actuators to generate lighter and more compliant designs. Full article
