Episode 19 From EMG to TLVs Picking the Right Occupational Exoskeleton with Dr Jason Gillette
Manage episode 504022962 series 3598595
Dr. Sugar and I are proud to be able to share Episode 19 of the Exoskeletons and Wearable Robotics Podcast for ExR's Patreon Supporters! This time, we are lucky to have as a guest Dr. Jason Gillette, who shares his impressions of occupational exoskeletons. His Biomedical Engineering degree, decades of hands-on expertise in ergonomics and multiple industrial exo projects have given him a deep understanding of the field. During this conversation, he is happy to share his observations on evaluating and task-matching industrial exoskeletons and wearable devices. Together, we discuss tools and methodologies for recording and analyzing job sites, from simple phone recording to EMG sensor studies and everything in between. The conversation flows between biomechanics to simple observations, underlyning the importance of understanding objective and subjective data when running pilots.
