Researchers Develop New Approach for Robotic Exosuit Assistance
The new approach relies on robotic exosuit assistance being calibrated to an individual, and it adapts to various different real-world walking tasks in just seconds. The bio-inspired system uses ultrasound measurements of muscle dynamics, which enables it to be personalized and activity-specific for users.
...“We used ultrasound to look under the skin and directly measured what the user’s muscles were doing during several walking tasks,” said Nuckols. “Our muscles and tendons have compliance which means there is not necessarily a direct mapping between the movement of the limbs and that of the underlying muscles driving their motion.”
...“From these pre-recorded images, we estimated the assistive force to be applied in parallel with the calf muscles to offset the additional work they need to perform during the push off phase of the walking cycle,” said Swaminathan.
