The coupling effect between elastic deformation and the rigid motion was concerned in the dynamic equations. At the same time, the flexible manipulators were assumed as Euler-Bernoulli beams, the elastic deformation of the manipulator was represented by modality truncation equations, both elastic and gravitational potential energy were considered to calculate the total energy for whole system, therefore the finial dynamic modeling is more accurate and simple than others published.

该方法考虑了柔性机械臂刚体运动和弹性变形之间的耦合影响，并将柔性机械臂假设为一段Euler-Bernoulli梁处理，将弹性变形用截断模态方程表示，同时考虑了弹性势能和重力势能的影响，得到的双连杆柔性机械臂的动力学模型具有模型准确、结构简单等特点。

Afterwards, we propose a new constant coefficients measurement method in dynamic equation of robot manipulators, this measurement method includes three groups of experiments: group one, let each joint of robot manipulator keep static to measure the constant coefficients in gravity term of dynamic equation and Coulomb frictional torque, group two: let only one joint of robot manipulator move at a constant velocity to measure the viscous frictional coefficient and constant coefficients in effective inertia of dynamic equation, group three: let only one joint of robot manipulator move at constant acceleration at a time to measure constant coefficients in Coriolis and centrifugal term and coupling inertia of dynamic equation.

让操作器单个关节恒速运动，在对驱动系统中传动机构，减速装置和电感系数综合考虑的基础上，这组实验对粘滞摩擦系数及有效惯量中常数系数进行测量。这种测量方法只要求旋转关节的驱动电机施加恒定电压，回转关节驱动电机施加正弦波电压。3。让操作器单个关节恒加速运动，这组实验测量动力学方程中哥氏力、离心力项和耦合惯量项中的常数系数，这种测量方法只要求单个关节匀加速运动，而其它各关节保持静止，这种测量方法虽然要求关节匀加速运动，但不必进行关节角加速度检测，而只需进行关节角位移和角速度检测即可，输入量直接给定为输入电压。

The manipulative person can not trust himself, he could not trust other people as well the manipulator tries to control himself by controlling other because he can't control himself. The most common manipulative behaviors include: intimidates, deceive, self- harm, demands, flatters, ingratiation and so on. The worst part of such behavior is that it will split the health professionals in some way. It also causes conflicts between nursing staff and disturbs the emotional status of them. To avoid these situations, all nursing staff should help patients with consistent attitude. In addition, nurses should master behavior of manipulators to reduce the chance of being manipulated. Helping patients to solve their problems may help build up the sense of trust and security and promote self-control. They will beable to increase recognition of behaviors, mature interpersonal relationship and gain self control.

操控者不会信任自己，更不能信任他人，他无法控制自己，所以由控制他人来控制自己，他们最常表现的操控行为，包括：威胁、欺骗、自我伤害、要求特权、谄媚、迎合他人等，比较严重的是他们会分化整个医疗团队的成员，造成成员之间的冲突及情绪上的困扰，为了避免这些状况产生，所有的成员应该要达成共识，用一致性的态度来帮助病人；另外，护理人员要熟知操控者的行为表现，减少被操控的机会，同时灵活运用问题解决方法，来协助病人对他人产生信任感、安全感及增加对自己的控制感，以达到增加行为的认知，学会成熟人际关系，达到自我控制的目的等预期结果。

It is able to perform spatial transformational movement, rotation, hoisting, tilting, planar rotation and tilted rotation. Based on configuration analysis, kinematic position equations were formulated, kinematic model of parallel fine-tuning structure was discussed as a key and inverse position analysis and velocity mapping equations were presented. Kinematic simulation of the mechanism was conducted using MATLAB software. A case study was provided, which applied the mechanism in tunnel erector assembling manipulators.

通过对该机构进行分析研究，建立其运动学位姿方程，重点探讨了并联微调机构的运动学模型，建立了其位置逆解与速度映射解析方程，运用MATLAB软件对该机构进行了运动学仿真分析；同时提供了该串并联机构应用于隧道管片拼装机械手的具体实例。

Because of the unstructured environments and the force impulse excitation of the following manipulators, the invertibility control input can not control the conducting manipulator exactly. In this paper, a new adaptive and sliding mode control scheme is developed assuming that all system parameters including the joint flexibility values are uncertain but within given bounds.

在以上方法的基础上，本文再对多杆柔性关节机械手在约束空间的轨迹优化规划问题进行了研究，首先利用坐标转换得出多杆柔性关节机械手的约束动力学模型，然后利用逆系统方法求出了系统在约束空间的次优化轨迹及力控制器。
