摘要: | 本研究針對pitch-yaw串接型機器蛇,利用中樞模式產生器(CPG)模型產生可微分步態,就機器蛇各關節的座標與接地點之變化進行模擬及分析,找出各種不同步態接地點的移動與模型參數之關係,並進一步實現於機器蛇上。所分析與實作於機器蛇上的六種步態分別為直線步態、轉彎步態、滑動步態、側向平移步態、旋轉步態和滾動步態。使用中樞模式產生器模型來實現機器蛇之步態有以下優點:可簡化控制演算法、提升運算速度、產生順暢的動作等。本研究針對串接型機器蛇的長度與節數提出一套旋轉步態之參數設定規則,最後並提出一套機器蛇各種步態參數設定的流程,使能系統而有效地產生機器蛇的步態。 The purpose of this paper is to implement differentiable gaits of pitch-yaw connecting snake robots through investigating the coordinates of each joints and the motion of ground points based on the central pattern generator (CPG) model. Six different gaits, i.e., rectilinear, turning, slithering, lateral shift, rotating and rolling gaits, have been analyzed and implemented on a real snake robot, which consists of 16 joints. Using CPG model to implement the gaits of snake robots can simplify thecontrol, accelerate the computational speed and smooth the movements. A new rule for the parameter setting of rotating gait was proposed for snake robots with different length and different number of joints. Finally, a procedure for the gaits determination of those differentiable gaits, based on CPG, has been developed. Thus the gaits of snake robots can be generated more systematically and efficiently. |
