They told stories of their wonderful feats with fowl, fish, and quadruped—how many wild ducks and turkeys they had shot, what"savage trout" they had caught, and how they had bagged the craftiest foxes, outwitted the most clever possums, and overtaken the fleetest deer, until I thought that surely the lion, the tiger, the bear, and the rest of the wild tribe would not be able to stand before these wily hunters.

他们夸耀自己打野禽和捉鱼的高超本领，不厌其烦地描述打了多少只野鸭和火鸡，捉住多少凶猛的鲑鱼，怎样用口袋捉狡猾透顶的狐狸，怎样施计捉住灵巧的松鼠，如何出其不意地捉住跑得飞快的鹿。

The main work of this paper: Firstly, Basing on the summarization and analysis of the walking mechanism, Parallel drive five-bar mechanism is applied for walking mechanism. And then the characteristic of the trail and positive kinematics as well as reverse kinematics are discussed. Secondly, the model of walking mechanism is established according to Parallel drive five-bar mechanism, and then a figure planning is designed for the foot-end trail. The characteristics of the parallel drive are emphasized to research in this paragraph by the method of insert value. At last, the simulation is performed in the ADAMS to compare the real result to the theoretical value. Thirdly, a sealed structure of a Quadruped Walking Robot is designed and established. The whole control system, including motor, sensor and control circuit, is sealed in the robot. Walking is derived in the way of the shaft driving and the dynamic torque sensor is used to the surrounding conditions of the robot's foot-end to be the foundation of the robot's control. At last, the applying principle of the dynamic torque sensor is researched in detail basing on the traditional sensor of the walking robot. Moreover, the principle is divided into several sorts to discuss. Finally, simulation and verification of the monitor principle are come through in the Mechanism of the Pro/Engineer.

论文的主要工作有：在对传统步行机构总结分析的基础上，提出将平面并联五杆机构应用于四足步行机器人的腿部结构，并对其轨迹特性、正运动学、逆运动学特性做了详细计算分析；依据平面并联五杆机构的模型，建立机器人步行机构的实体模型，对其足端的轨迹做了图谱规划，并利用插值法对并联驱动端的特性曲线作了研究，并在ADAMS中进行仿真，将结果与理论值相比较；然后设计了一套四足步行机器人密封装配结构设计方案，建立四足步行机器人单足结构、驱动以及传感器监测的三维实体模型，将机器人的整个控制系统，密封装配在步行机器人的机体中，通过轴传动来驱动步行机构实现步行，采用动态扭矩传感器监测步行机构的驱动关节受到的扭矩变化，从而获得四足步行机器人足端的周围情况，为步行机器人的控制方案奠定了基础；论文的最后在分析步行机器人传统控制传感器的基础上，详细分析了动态扭矩传感器的监测原理，并分几种情况分别分析了其监测原理，并在Pro/E的Mechanism模块中实现了监测原理的仿真与验证，最后给出了传感器监测信息与系统判断之间的关系。

The greatness of the prize induced Oedipus, a man of wisdom and penetration, but lame from wounds in his feet, to accept the condition and make the trial: who presenting himself full of confidence and alacrity before the Sphinx, and being asked what kind of animal it was which was born four-footed, afterwards became two-footed, then three-footed, and at last four-footed again , answered readily that it was man; who at his birth and during his infancy sprawls on all fours, hardly attempting to creep; in a little while walks upright on two feet; in later years leans on a walking stick and so goes as it were on three; and at last in extreme age and decrepitude, his sinews all failing, sinks into a quadruped again, and keeps his bed.

这丰厚的彩头引得俄狄浦斯，这位富于智慧和洞察力，却因受伤而瘸腿的人，接受了条件，前去一试：他信心十足，心情放松的出现在斯芬克斯面前，被问到哪种动物生下来四条腿，后来只有两条腿，又后来变成三条腿，最后又回到四条腿。他马上就回答说这是人，人在刚刚出生和婴儿阶段时以四肢着地，艰难的试着爬行；不久之后就两脚直立行走；到了晚年要着拐棍走路所以是三条腿；最后风烛残年了，腿骨无力，又回到四足状态，呆在床上。
