By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-New research on Robotics is the subjec t of a report.According to news originating from Shenyang,People's Republic of China,by NewsRx correspondents,research stated,"For patients with functional motor disorders of the lower limbs due to brain damage or accidental injury,re storing the ability to stand and walk plays an important role in clinical rehabi litation.Lower limb exoskeleton robots generally require patients to convert th emselves to a standing position for use,while being a wearable device with limi ted movement distance." Our news journalists obtained a quote from the research from the Chinese Academy of Sciences,"This paper proposes a reconfigurable behavioral assistive robot t hat integrates the functions of an exoskeleton robot and an assistive standing w heelchair through a novel mechanism.The new mechanism is based on a four-bar li nkage,and through simple and stable conformal transformations,the robot can sw itch between exoskeleton state,sit-to-stand support state,and wheelchair state .This enables the robot to achieve the functions of assisted walking,assisted standing up,supported standing and wheelchair mobility,respectively,thereby m eeting the daily activity needs of sit-to-stand transitions and gait training.T he configuration transformation module controls seamless switching between diffe rent configurations through an industrial computer.Experimental protocols have been developed for wearable testing of robotic prototypes not only for healthy s ubjects but also for simulated hemiplegic patients.The experimental results ind icate that the gait tracking effect during robot-assisted walking is satisfactor y,and there are no sudden speed changes during the assisted standing up process,providing smooth support to the wearer.Meanwhile,the activation of the main force-generating muscles of the legs and the plantar pressure decreases signific antly in healthy subjects and simulated hemiplegic patients wearing the robot fo r assisted walking and assisted standing-up compared to the situation when the r obot is not worn.These experimental findings demonstrate that the reconfigurabl e behavioral assistive robot prototype of this study is effective,reducing the muscular burden on the wearer during walking and standing up,and provide effect ive support for the subject's body."
