Background: Manipulator is widely used in the manufacturing industry because it can imitate some movements of human hands, and replace human hands to complete some high-risk and heavy labor or carry out man-machine cooperation. Flexible soft manipulator made of flexible materials is a new field of the manipulator. Investigation of the material and driving mode of the flexible soft manipulator is helpful to im Read More

Background: In China, there are more than 2 million patients with hand function impairment caused by trauma and stroke each year. Since the hand is an important sensory and motor organ of the human body, the loss of hand function seriously affects people's daily activities and work. The current hand function rehabilitation robots are mainly rigid. The rigid robot has the problems of fixed rehabilitation track, high rigidity, a Read More

Background: At present, with the rapid development of technology in medical treatment and rescue, how to reduce the operational complexity caused by limited space has become one of the hot topics. For example, in search and rescue, it is difficult for people to enter these high-risk areas due to various restricted geographic environments. During some medical treatment processes, minimally invasive surgery is difficult to Read More

Background: The high-speed motorized spindle system is the main component and the most significant heat source of high-precision CNC machine tools in mechanical processing. Plenty of research shows that 60%~80% of the machining accuracy error comes from the thermal deformation of each part in automated manufacturing. Therefore, it is urgent to study the control method of thermal error for motorized spindle syste Read More

Background: Roller bearing is a widely used component in modern machinery. It has the advantages of small friction, low starting torque, high rotation accuracy, less power loss, and high efficiency. The researches on the structure and working principle of new type roller bearings are conducive to improving the performance of bearings. Therefore, it is necessary to analyze and summarize the recent research. Objectiv Read More

Background: Only a fraction of the produced social media data is usable in mental health assessment. So the problem of sufficient training data for deep learning approaches arises. Data sufficiency can be presented in terms of number of users or the number of posts per user. Objective: We examine the data need of machine learning and deep learning models for a practical system and let researcher choose best fitting mod Read More
