摘要： The new era with prosperous artificial intelligence (AI) and robotics technology is reshaping the materials discovery process in a more radical fashion. Here we present authentic intelligent robotics for chemistry (AIR-Chem), integrated with technological innovations in the AI and robotics fields, functionalized with modules including gradient descent-based optimization frameworks, multiple external field modulations, a real-time computer vision (CV) system, and automated guided vehicle (AGV) parts. AIR-Chem is portable and remotely controllable by cloud computing. AIR-Chem can learn the parametric procedures for given targets and carry on laboratory operations in standalone mode, with high reproducibility, precision, and availability for knowledge regeneration. Moreover, an improved nucleation theory of size focusing on inorganic perovskite quantum dots (IPQDs) is theoretically proposed and experimentally testified to by AIR-Chem. This work aims to boost the process of an unmanned chemistry laboratory from the synthesis of chemical materials to the analysis of physical chemical properties, and it provides a vivid demonstration for future chemistry reshaped by AI and robotics technology.

摘要： MCU端软件结构设计质量是影响循迹机器人工作效率、适应突发任务变更和异常状态能力的重要因素,但目前普适性的改进手段不多。本文通过遥控竞赛机器人任务特征分析,设计基于位置关联的控制设备与机器人间通讯协议,使用链表进行任务节点的封装和序列构造,最终基于位置信息实施控制流程。结果表明,任意给定任务序列能够准确实现。相对顺序式控制流程,该软件结构和关联流程设计在路径优化的同时还能适应任务序列的重整定。

摘要： 针对视觉伺服机器人系统中存在的动力学不确定性的问题,提出了一种基于动态补偿与摩擦力补偿的自适应鲁棒控制方案。该方案创新性在于将图像平面上的输出信号反馈至关节空间,结合动力学模型的参数线性化性质设计自适应算法在线标定不确定的动力学参数,同时无需测量摩擦力,通过设计自适应鲁棒项在线预估摩擦力。通过李亚普洛夫稳定性分析工具能证明提出的控制方案可以全局镇定闭环系统,同时实现精确的图像轨迹跟踪。仿真结果表明了所提出的自适应鲁棒控制方法的有效性。

摘要： This paper proposes a new double-stator magnetless vernier (DSMV) machine for direct-drive robotics. By artfully incorporating the double-stator structure, vernier configuration and dc excitation together, this DSMV machine yields the merits of the flux control capability, low-speed operation, high torque output, free maintenance, and high cost-effectiveness. Also, the optimizations of the rotor-teeth arc angle, stator-teeth arc angle, and current phase angle are carried out for the improvement of torque performance. In this way, the torque ripple of the machine is significantly reduced up to a tiny value of 3.67%. Moreover, the rational dc current range and the rotational speed range are obtained through the performance analysis with flux regulation. In addition, the comparison is performed with the conventional surface-mounted permanent-magnet machine. Therefore, the proposed machine shows the distinct features and is fit for the special application. Finally, both theoretical derivation and simulation are given for the validation of the machine design.

摘要： Ever since digital technology entered in the operating theater (OT) surgery has moved out through one of the big transformation on account of medical world and now we are foreseeing the era of digital OT. Robotic assisted surgery (RAS) is a way of technological development in the medical environment that uses robotic structure to assist in surgical measures. RAS was designed to beat the limitations of Minimal Invasive Surgery (MIS) and to improve the ability of medical doctor during surgery. The paper depicts the control methodology for surgical robots based on the combination of fuzzy logic control (FLC) with sliding mode control (SMC). The appreciable features of SMC like simplicity in design and high degree of robustness motivate researchers to employ this methodology in robotics. Nevertheless, the destructive chattering phenomenon is circumvented by espousing FLC in SMC. Additionally, the output gain of fuzzy sliding mode control (FSMC) is online tuned by a supervisory fuzzy logic control (SFLC), which results in chattering diminution. System stability is investigated using Lyapunov theorem. All numerical simulations have been carried out using MATLAB tool for 2 DOF surgical robot manipulator formulated for high speed trajectory tracking and for the typical condition during surgery. Moreover, the performance has been validated in real-time using Opal-RT Lab simulator show the efficacy of the proposed methodology. The simulation as well as real time digital simulator (OP-4500) results of FSMC and supervisory fuzzy logic based sliding mode control (SFSMC) are compared with the conventional SMC which represents the improvement of control law for attainment of optimized results by rejecting perturbations and achieving the desired system performance within a specific band of operation.
