Gesture recognition has always been a research hotspot in the field of human-computer interaction. Its purpose is to realize the natural interaction with the machine by recognizing the semantics expressed by gesture. In the process of gesture recognition, the occlusion of gesture is an inevitable problem. In the process of gesture recognition, some or even all of the gesture features will be lost due to the occlusion of the gesture, resulting in the wrong recognition or even unrecognizability of the gesture. Therefore, it is of great significance to study gesture recognition under occlusion. The single shot multibox detector (SSD) algorithm is analyzed, and the front-end network is compared. Mobilenets is selected as the front-end network, and the Mobilenets-SSD network is improved. In tensorflow environment, based on the improved network model, the self-occlusion gesture and object occluding gesture are trained in color map, depth map, and color and depth fusion respectively. The recognition models of self-occlusion gestures and object-occlusion gestures in color map, depth map, and color and depth fusion are obtained. And compare and analyze the learning rate, loss function, and average accuracy of various models obtained for occlusion gesture recognition.

“…Before the stress field analysis, the ladle was divided into grids, and a fine grid was separately divided for the area of the ladle shell and the hoop plate, rib plate, and trunnion. 61 Then the temperature field results in the previous article are loaded into the stress analysis. From the analysis of the temperature field under ladle baking and holding conditions, the temperature distribution under the two working conditions is roughly the same.…”

For meeting the comprehensive requirements of "super insulation," "lightweight," and "longevity" of the contemporary ladle, this article designs a new kind of lightweight ladle with heat preservation and longevity performance, and based on steady-state analysis method and numerical simulation technology, the comparison of temperature distribution between new lightweight and traditional ladle under typical operating modes is made and analyzed. The simulation results of temperature field prove that the performance of heat preservation in new kind of lightweight ladle has been improved obviously from the two aspects of ladle shell temperature and molten steel file rate. At the same time, the simulation results of stress field indicate that the stress of designed lightweight ladle reduced and distributed more evenly, which is conducive to prolonging the work time in-service of the ladle. Finally, based on the field test, the simulation is proved to be effective, and the designed ladle structure achieves the expected purpose.

“…This robot is flexible to suit to the physiological characteristics of the patient. [27][28][29] However, the patient's left and right legs are not fixed, and the movement gait is easily deformed during the rehabilitation process. The horizontal robot is only suitable for early bed training for rehabilitation patients, and its functions are limited.…”

Compound lower limb vibration training rehabilitation robot

Yin

et al. 2020

This paper uses a bionic lower limb rehabilitation mechanism combined with a running frame structure to simulate human gait movement for lower limb rehabilitation training. The vibration excited by the vertical vibration module causes the muscle to oscillate, and the mechanical vibration excites the neuromuscular system to obtain corresponding rehabilitation functions. The robot system is modeled in three dimensions, and the static analysis and modal analysis of the running frame are carried out. The mechanism and application of vertical vibration in the key technology are clarified, and the vibration element in the vertical vibration device is analyzed. The vibration theory is deduced, and the vibration displacement figure is drawn using simulation software. The related cooperative vibration spring has also been analyzed with single-degree-of-freedom damping vibration, and the spring's center of mass movement, momentum, and position changes over time are illustrated. The design of the robot system solves the current situation of single movement of the lower limb rehabilitation robot and unsatisfactory rehabilitation effect, laying a foundation for the practical application of the subsequent lower limb rehabilitation robot system.
