Design and optimization of a novel lower limb assisted smart robot technology: Evaluation of human-computer interaction based lower limb assisted robot design

Abstract

A new type of intelligent, natural and comfortable lower limb muscle assist robot based on daily operations. It can represent the most cutting-edge design innovation at this stage with minimizing the stress on the body and providing the most valuable technical solution in daily design and operation work. At the same time we have to develop the design and evaluation of human-computer interaction based lower limb assistive robot design with the help of scientific technology. This paper focuses on four research direction areas. a) Aesthetically, the four-piece design of the new lower extremity muscle-assisted robot (i.e., mechanical structure, belt, leg brace, and walking boot) looks more like sports equipment than a wearable robot. b) Inspired by the human body, it combines soft and hard components and a mix of materials for the robot that reflects the body's own muscles, tissues, and bones. The layer closest to the body is made of soft, stretchable fabrics (i.e., neoprene and fly stitch). c) To increase strength, the outer layers become progressively stiffer toward a robotic limb made of carbon fiber, thereby maximizing strength while minimizing weight. d) Intelligent. By being equipped with sensors, it can dynamically capture the user's movement trend to make dynamic adjustments, providing precise assistance and force enhancement effects. Data as well as positioning information can be viewed in the accompanying APP. The validation of this solution is through the use of advanced technology where the new lower limb muscle assist robot is symbiotic with the wearer. The combination of machine learning, force and position micro-sensors within the fabric layer, and slim yet powerful axial flux motors at the body's natural rotation points, allows for seamless coordination between body and machine. One of the most innovative solutions and the future of the industry, the design and optimization of the new lower limb muscle assist robot technology is demonstrated by physical operation cases that are applicable and forward-looking in the future.
