  • R-SLAM--Resilient localization and mapping

    Accurate pose estimation plays an important role in solution of simultaneous localization and mapping (SLAM) problem, required for many robotic applications. This paper presents a new approach called R-SLAM, primarily to overcome systematic and non-systematic odometry errors which are generally caused by uneven floors, unexpected objects on the floor or wheel-slippage due to skidding or fast turns.The hybrid approach presented here combines the strengths of feature based and grid based methods to produce globally consistent high resolution maps within various types of environments.

  • Autonomous+Robots+Modeling,+Path+Planning

    A kinematically redundant manipulator is a serial robotic arm that has more independently driven joints than are necessary to define the desired pose (position and orientation) of its end-effector. With this definition, any planar manipulator (a manipulator whose end-effector motion is restrained in a plane) with more than three joints is a redundant manipulator. Also, a manipulator whose end-effector can accept aspatialposeisaredundant manipulator ifithas morethan sixindependently driven joints. For example, the manipulator shown in Fig. 1.1 has two 7-DOF arms mounted on a torso with three degrees of freedom (DOFs). This provides 10 DOFs for each arm. Since the end-effector of each arm can have a spatial motion with six DOFs, the arms are redundant.

  • Intelligence_-A-Modern-Approach

    Artificial Intelligence (AI) is a big field, and this is a big book. We have tried to explore the full breadth of the field, which encompasses logic, probability, and continuous mathematics; perception, reasoning, learning, and action; and everything from microelectronic devices to robotic planetary explorers. The book is also big because we go into some depth. The subtitle of this book is “A Modern Approach.” The intended meaning of this rather empty phrase is that we have tried to synthesize what is now known into a common frame- work, rather than trying to explain each subfield of AI in its own historical context. We apologize to those whose subfields are, as a result, less recognizable.

  • 工業機器人動力學仿真及有限元分析

    自1995年美國推出世界上第一臺Unimate型機器人以來,工業機器人的數量在世界范圍內不斷增長,焊接從一開始就是工業機器人應用最重要的領域之一,焊接機器人能顯著提高焊接質量和工作效率,減輕工人的勞動強度,降低生產成本和對工人操作技術的要求,它的廣泛應用和國產化、產業化,對實現我國在21世紀前半葉成為世界制造強國的目標具有非常重要的意義。本文針對一臺6R焊接機器人,系統分析了其動力學性能和結構特性。首先運用D-H方法,建立了該機器人的連桿坐標系,在此基礎上,推導了機器人的運動學正反解、求解了機器人的雅可比矩陣;對機器人進行了詳細的靜力學、動力學分析:利用robotic Toolbox和IMatlab編程實現了機器人的運動學可視化仿真,直觀地反映了機器人各關節變量與末端位姿矩陣之間的關系,為機器人的三維圖形仿真提供了參考;利用Matiab/Simulink建立了機器人的動力學仿真模型,編制了相應的Matlabi算程序,通過動力學仿真,得到了運動過程中機器人各關節驅動力矩的變化曲線,為合理選擇驅動電機、軸承等關鍵零部件以及機器人的實時和最優控制提供了依據針對機器人操作機的機構優化設計,對機器人關鍵承載部件進行了分析和簡化,建立了關鍵承載部件的有限元分析模型,選取了最危險的受力狀況作為分析工況,對各部件進行了靜力分析,得到了各部件的應力和位移分布,獲得了各部件的最大變形,對機器入局部剛度進行了評價。
