Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Investigators publish new report on Ro botics - Robotics and Automation. According to news reporting out of Tianjin, Pe ople's Republic of China, by NewsRx editors, research stated, "Lower-limb exoske letons can improve human mobility and endurance, especially for people with leg impairments. To minimize metabolic penalty and maximize assistance capacity, the design of the mobile exoskeleton needs to compromise between the system weight and actuation power." Financial support for this research came from National Natural Science Foundatio n of China (NSFC). Our news journalists obtained a quote from the research from Nankai University, "In the paper, we developed a lightweight high-torque mobile bilateral ankle exo skeleton with compliant end-effectors and a high-efficiency actuation. The syste m can provide 80 Nm assistive torques for both ankles with 3.4 kg entire exoskel eton weight by actuators' parallel connection and cooperative operation. Develop ed embedded hardware implemented a real-time torque controller comprising the da mping-injected feedback control, model-based feedforward compensation, and itera tive learning, achieving more than 10 Hz gain-limited closed-loop bandwidths and less than 2% torque tracking error. Preliminary physiological exp eriments demonstrated the exoskeleton's ability to reduce soleus muscle activiti es by over 50% at different walking speeds."
