摘要： 提出了一种基于3维运动测量系统Optotrak3020的柔性关节模块机器人动力学模型参数辨识方法.首先将机器人的动力学模型参数化为不包括刚度力矩的线性形式,避免了参数矩阵的标定问题.激励轨迹基于有限的傅里叶级数函数,采用自适应遗传算法得出了优化的傅里叶级数系数.机器人每一关节单独跟随优化激励轨迹进行运动,同时电机位置、连杆位置、电机力矩被实时测量并记录.最后,采用经典的线性最小二乘参数辨识方法,对PowerCube模块化机器人的前3个关节进行了动力学参数辨识实验,得出了机器人动力学模型参数.

摘要： Large-scale conformational rearrangement of a lid subdomain is a key event in the interfacial activation of many lipases. We present herein a study in which the large-scale "open-to-closed" movement of Burkholderia cepacia lipase lid has been simulated at the atomic level using a hybrid computational method. The two-stage approach combines path-planning algorithms originating from robotics and molecular mechanics methods. In the first stage, a path-planning approach is used to compute continuous and geometrically feasible pathways between two protein conformational states. Then, an energy minimization procedure using classical molecular mechanics is applied to intermediate conformations in the path. The main advantage of such a combination of methods is that only geometrically feasible solutions are prompted for energy calculation in explicit solvent, which allows the atomic-scale description of the transition pathway between two extreme conformations of B. cepacia lipase (BCL;open and closed states) within very short computing times (a few hours on a desktop computer). Of interest, computed pathways enable the description of intermediate conformations along the "open-to-closed" conformational transition of BCL lid and the identification of bottlenecks during the lid closing. Furthermore, consideration of the solvent effect when computing the transition energy profiles provides valuable information regarding the feasibility and the spontaneity of the movement under the influence of the solvent environment. This new hybrid computational method turned out to be well-suited for investigating at an atomistic level large-scale conformational motion and at a qualitative level, the solvent effect on the energy profiles associated with the global motion.

摘要： A novel 4-UPS-RPS high-speed spatial 5-Degree of freedom parallel robot was proposed. The stationary platform of the parallel robot is connected with the moving platform by the same four UPS (universal joints-prismatic pairs-spherical joints) driving limbs and a RPS (revolution joints-prismatic pairs-spherical joints) driving limb. In order to grasp the dynamic characteristics of 4-UPS-RPS high-speed spatial parallel robot, and privide the important theoretical base of the optimization design and the system control for 4-UPS-RPS parallel robot, the rigid-flexible coupled dynamics modeling and analysis for the parallel robot were realized. The rigid-flexible virtual prototype of 4-UPS-RPS parallel robot was constructed by the united application of CAD, CAE and visual technologies while the driving limbs and spherical joints were treated as flexible bodies, the moving platform, stationary platform and other joints of parallel robot were treated as rigid bodies. Based on the rigid-flexible virtual prototype, the dynamic behaviors, including kinematics output response, dynamic stress of driving limbs and natural frequency, were obtained. The simulation results show that the rigid-flexible model proposed can indicate the dynamic characteristics of parallel robot, the flexibility of driving limbs are demonstrated to have significant impact on system kinematics and dynamics.

摘要： The article offers information on the Bluefin-9 unmanned underwater vehicle (UUV) of Bluefin Robotics Corp. which uses Microsoft Office SharePoint Server (MOOS)-IvP autonomy system software. It states that the of the MOOS-IvP, an open-source C++ software, allows an ocean sensing of UUV without the need for human operators. It says that the software controls the UUV with its Huxley software operating system.
