In the past few years, we have covered plenty of exosuits that can assist you in walking and other activities indoors and outside. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have taken the idea to the next level by calibrating robotic exosuit assistance to individuals. It can adapt to a variety of walking tasks in seconds. The system relies on ultrasound measurements to develop personalized assistance. As they explain:
We used ultrasound to look under the skin and directly measured what the user’s muscles were doing during several walking tasks. 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.
