Human-computer interaction-based robotic design and development and control system testing —Prototyping and implementation testing study of a robotic hand

Abstract

One of the most challenging issues in the development of existing robotic hand design and development based on existing policies and in everyday people’s needs for interactive technologies that can assist patients who have lost hand manipulation due to neurological or stroke induced. This paper focuses on robotic hand designs aimed at assisting post-stroke patients with enhanced human-computer interaction, including four innovative research direction areas. a) Aesthetically, the four-piece human-computer interaction-based robotic hand design (i.e., internal mechanics, five elastic bands, electrodes, and soft skin-friendly material) looks more like sports equipment than a wearable machine. b) Inspired by human palm design engineering, the The human-computer assisted manipulator is an innovative form of mixing soft and hard components and materials, constructed from layers closest to the body made of soft, stretchable fabrics (i.e., neoprene and fly stitch fabric). 3D printed flexible TPU components, which use BOA dials to increase or decrease finger tension. c) For added strength, the product is worn on the palm of the hand, and then tightening the wrist strap prevents unwanted movement This is an innovative patent and is integrated into the glove. This is innovative and patented and the BOA dial integrated in the glove is attached to five elastic bands, one for each finger, which are secured in place by a channel placed on the TPU piece. This makes it lighter in weight. d) Intelligent. By being equipped with sensors, it can be intelligently sensed internally to properly release tension with promoting blood circulation in the wearer’s hand, they push the BOA dial in and rotate it to increase tension, and to release tension, the user simply pulls the BOA dial upward. This will help the muscles relax and restore normal fluid movement. The data can be viewed in the accompanying app. After researching and investigating the existing human-machine interaction based robotic hand mostly made of steel, the sensor cannot sense the material of the object well after wearing, temperature, and the set finger bending angle cannot fit the object well. Through experimental data to test the best working area and experimental daily use force, we study and adjust the best for the human-machine interaction-based robotic three-dimensional work treatment area. This is one of the most innovative solutions with the future of the industry, this research focuses on the process of human-computer interaction for the patient’s hand is also required for a large number of interaction resources also with human resources. The development of a more skin-friendly, safer, and less expensive human-computer interaction-based manipulator (HES) that can operate by itself is sufficient to support all daily living activities (ADLs) of the hand. Finally, the physical field study experiments also showed that the device is flexible and can be customized by anyone for the right size and use.
