Minimally invasive surgery (MIS) has gradually become the preferred method of surgery due to its advantages of less trauma and faster recovery. However, the small and complex surgical area places high demands on the performance of the robot and the skill level of the doctor. In order to avoid the damage of other healthy organs with surgical instruments during the operation, a variable workspace of a continuum robot is designed in this paper. The information of the dynamic transformation of the surgical environment is used to continuously update the workspace of the continuum robot. For healthy vital organs, the workspace can actively shield its corresponding posture. Experiments have verified that for a variety of complex surgical scenarios, the variable workspace can simply and effectively implement the safety protection of healthy organs, and can avoid interference when multiple arms work together.

AGV state monitoring is becoming increasingly important for production system safety in digital workshops. This paper develops a global and first-person view fusion to monitor the AGV (Automated Guided Vehicle) running state in the complex digital workshops. Based on the affine transformation model, the AGV running states, i.e., position, velocity and orientation are estimated by the global camera with the assistance of ArUco markers, which are pasted on the front side of the AGV. Besides, the first-person view camera is used to implement pedestrian detection and distance measurement based on the YOLOv3 model. It is noticeable that the pitch angle is considered for distance measurement, and an improved triangular model for distance measurement is proposed. The effectiveness of the proposed method has been verified in our built platform.

A novel tactile P300 paradigm was proposed for Brain-Computer Interface(BCI), in which only two types of stimuli was used to distinguish different targets. We also adapted an algorithm for intention recognition, which used spatial information to distinguish different stimulation sites, and frequency information to identify attended-target stimuli and disturbances. Our novel paradigm was verified on both vibration and electrical stimuli modes, and achieved an average classification accuracy of 95.21% for vibration stimuli mode and 94.88% for electrical stimuli mode, respectively. Furthermore, we evaluated performances of brain's functional connectivity by the correlation coefficient, and preliminarily explored the similarities and differences between vibration stimuli mode and electrical stimuli mode.

As the country pays more and more attention to energy saving, emission reduction and environmental protection, electric vehicles have become a hot spot in the development of automobile technology. Power battery determines the comprehensive performance of electric vehicle, and the protective performance of battery box directly affects the safety of the vehicle. Therefore, the battery box is taken as the research object, and the box is designed according to the power battery. The box body is arranged under the chassis of the car, and the 3D model and finite element model of the box body are established based on SolidWorks and ANSYS Workbench software. The static performance, impact and modal analysis of the box body are carried out under typical working conditions. Based on the stiffness of the lower box, the box is optimized and verified by modal analysis. The analysis results show that the stiffness of the box can be increased by adding X type stiffeners at the bottom of the box, and the designed power battery box can meet the actual safety requirements of the car.

Aiming at providing effective technical means for intelligent bathing and low-intensity care for the semi-disabled elderly, an impedance iterative learning sliding mode control (IILSMC) scheme for robot-assisted bathing with unknown model parameters is investigated in this paper. Firstly, the desired trajectory is adjusted by impedance control in order to ensure the active compliance control of the robot-assisted bathing. Secondly, iterative learning control (ILC) is implemented to dynamically estimate the unknown model parameters, and reconstructed trajectory method is employed to ensure the convergence accuracy of iterative learning with any initial conditions. Thirdly, as for handling nonparametric uncertainties, external disturbances and the human-machine interaction (HMI) torque, adaptive sliding mode control (SMC) is proposed where the chattering problem in output torque is suppressed by adaptive method. Based on the composite energy function (CEF) method, the convergence of the double closed-loop system in the time domain and iterative domain is proved. Finally, through co-simulation of MATLAB and ADAMS, tracking errors of all joint angles can be maintained within 0.002rad with constant HMI force. The simulation results demonstrate that the IILSMC strategy is verified to be effective and superior.

We present an improved A* algorithm based on road boundary constrainted for road scenes such as campuses, communities, and industrial parks. Firstly, the LIDAR scans the surrounding environment and saves it in the point cloud data, pre-processes the point cloud and acquires the road boundary, then translates the acquired road boundary to generate a minimal cost feasible domain, and finally adds the feasible domain to the A* algorithm for path planning. To verify the feasibility of the method, experiments were conducted in both simulated and real environments. The experimental results show that the method can improve the problem of the paths planned by the A* algorithm being too close to the road edges and reduce the influence of road boundaries when the mobile robot is moving outdoors.

In order to meet the demand for autonomous feeding of people with upper limb dysfunction, a meal-assistance structure which is composed of modular lightweight robot arm, dexterous feeding hand and rotating plate was designed. The kinematics model of the meal-assistance robot is established by the Modified D-H method, and the forward and inverse kinematics are solved. Based on the variation of the robot's teaching posture parameter, the working mission segments of the robot were divided into four segments and the motion trajectory of the robot was planned by quintic B-spline. The trajectory planning result shows that the joint curve is smooth and continuous, the trajectory of the end of the spoon is stable, and the posture varys are smooth as expected.

As the core component of the atomic force microscope(AFM), the probe directly affects the measurement results. Many AFM-based experiments require control validation of the same target in a sample in different modes. The existing dual-probe system is complex, cannot switch the same target, and cannot be applied to the existing commercial AFM system. In this paper, an integrated dual-probe design based on a common probe is proposed, and a single optical path lever is used for sensing, which can quickly switch imaging at the same target. A U-shape dual-probe structure was designed, and the single-optical path signal decoupling was realized by distinguishing the resonant frequencies of the dual-probes. The designed integrated dual-probe can perform different modifications on the tip to achieve rapid switching imaging of the same target with different functions, and is fully compatible with commercial AFMs without the limitations of systems and environments.

Based on the principle of constant total potential energy of the system, we designed a lower limb rehabilitation robot for MMT-2 level patients. It balanced The gravity of the patient's leg to a certain extent so that the patient can make full joint range of motion. After determining the operation range of each joint in human lower extremity and the average gravity of the leg, a specific structure was designed and the overall static and kinematic analyses were performed to verify that the stiffness and strength of the structure met the requirements and could achieve the required range of motion.
