Towards Human-like Walking with Biomechanical and Neuromuscular Control Features: Personalized Attachment Point Optimization Method of Cable-Driven Exoskeleton

The cable-driven exoskeleton can avoid joint misalignment, and is substantial alterations in the pattern of muscle synergy coordination, which arouse more attention in recent years to facilitate exercise for older adults and improve their overall quality of life. This study leverages principles from neuroscience and biomechanical analysis to select attachment points for cable-driven soft exoskeletons. By extracting key features of human movement, the objective is to develop a subject-specific design methodology that provides precise and personalized support in the attachment points optimization of cable-driven exoskeleton to achieve natural gait, energy efficiency, and muscle coordination controllable in the domain of human mobility and rehabilitation. To achieve this, the study first analyzes human walking experimental data and extracts biomechanical features. These features are then used to generate trajectories, allowing better natural movement under complete cable-driven exoskeleton control. Next, a genetic algorithm-based method is employed to minimize energy consumption and optimize the attachment points of the cable-driven system. This process identifies connections that are better suited for the human model, leading to improved efficiency and natural movement. By comparing the calculated elderly human model driven by exoskeleton with experimental subject in terms of joint angles, joint torques and muscle forces, the human model can successfully replicate subject movement and the cable output forces can mimic human muscle coordination. The optimized cable attachment points facilitate more natural and efficient collaboration between humans and the exoskeleton, making significant contributions to the field of assisting the elderly in rehabilitation

Humanoid Robot handling Hand-Signs Recognition

Recent advancements in human-robot interaction have led to tremendous improvement for humanoid robots but still lacks social acceptance among people. Though verbal communication is the primary means of human-robot interaction, non-verbal communication that is proven to be an integral part of the human interactions is not widely used in humanoid robots. This thesis aims to achieve human-robot interaction via non-verbal communication, especially using hand-signs. It presents a prototype system that simulates hand-signs recognition in the NAO humanoid robot, and further an online questionnaire is used to examine people's opinion on the use of non-verbal communication to interact with a humanoid robot. The positive results derived from the study indicates people's willingness to use non-verbal communication as a means to communicate with humanoid robots, thus encouraging robot designers to use non-verbal communications for enhancing human-robot interaction

Robôs humanóides e a interação humano-máquina na cultura japonesa: uma exploração do imaginário tecnológico contemporâneo

TCC (graduação) - Universidade Federal de Santa Catarina. Centro de Filosofia e Ciências Humanas. HistóriaNeste Trabalho de Conclusão de Curso intento realizar um ensaio bibliográfico, com trabalhos, artigos, teses e livros - sobre a relação Humano-Máquina no Japão contemporâneo. Com foco na hipótese heurística – relação animismo-natureza – que existe para questionar a relação japonês-androide na contemporaneidade. Através desse questionamento, entrarei nos pontos de discussão específicos de minha pesquisa, onde abordarei a grande participação mundial do Japão na produção de robôs, liderando principalmente o mundo pós-industrial no desenvolvimento de robôs humanóides, discutindo a questão cultural japonesa em lidar com os robôs, através de suas crenças religiosas e filosóficas, mostrando que o Japão possui um histórico de relação com robôs desde o século XVII, a partir dos Karakuri Ningyo, considerado o primeiro robô japonês. Procuro então discutir a hipótese de como essas crenças religiosas e mitológicas do povo japonês são fatores que vem a contribuir para essa relação Humano-Máquina no Japão, discutindo essa interação dos japoneses com a tecnologia robótica
