Designing
Exoskeletons and Prosthetic Limbs that Enhance Human Performance
Steven H. Collins, PhD
Stanford University - Mechanical Engineering
Department |
Abstract: "My central research
goal is to develop wearable robotic devices that improve mobility and quality
of life, especially for people with disabilities. My laboratory uses three
complementary approaches. First, we develop tools to speed and systematize the
design of prostheses and exoskeletons. Humans are complex, limiting the
effectiveness of typical robotics design methods, so we have developed a new
approach that utilizes versatile, laboratory-based emulator systems. Second, we
leverage our emulators in basic scientific experiments aimed at discovering and
characterizing new methods of assistance. Our versatile hardware allows rapid
implementation of new ideas, controlled characterization of human response to
device functionality, and new approaches to design and prescription involving
online adaptation and patient-specific device optimization. Finally, we
translate successful approaches into energy-efficient mobile devices. For
example, we recently demonstrated an ankle exoskeleton that uses no energy
itself yet reduces the metabolic energy cost of human walking. We are currently
developing actuators based on electrostatic adhesion that are both energy
efficient and controllable, which will enable new types of high-performance
wearable robots."

Stanford,
Designing
robotic prostheses and exoskeletons that improve human
mobility
Biosketch: Steven H.
Collins received his BS in Mechanical Engineering in 2002 from Cornell
University, where he performed research on passive dynamic walking robots with
Andy Ruina. He received his PhD in Mechanical Engineering in 2008 from the
University of Michigan, where he performed research on the dynamics and control
of human walking with Art Kuo. He performed postdoctoral research on humanoid
robots with Martijn Wisse at TU Delft in the Netherlands. He was a professor of
Mechanical Engineering and Robotics at Carnegie Mellon University for seven
years. In 2017, he joined the faculty of Mechanical Engineering at Stanford
University, where he teaches courses on design and robotics and directs the
Stanford Biomechatronics Lab. His primary focus is to speed and systematize the
design and prescription of prostheses and exoskeletons using versatile device
emulator hardware and human-in-the-loop optimization algorithms (Zhang et al.
2017, Science). Another focus is efficient autonomous devices, such as
highly energy-efficient walking robots (Collins et al. 2005, Science)
and exoskeletons that use no energy yet reduce the metabolic energy cost of
human walking (Collins et al. 2015, Nature). He is a member of the
Scientific Board of Dynamic Walking and of the Editorial Board of Science
Robotics. He has received the Young Scientist Award from the American
Society of Biomechanics, the Best Medical Devices Paper from the International
Conference on Robotics and Automation, and the student-voted Professor of the
Year in his department.
