摘要: 设计并研制具有柔性元件的可采用人造壁虎脚掌吸附材料的足式仿壁虎机器人结构。针对采用人造壁虎脚掌吸附的足式爬壁机器人,仿照生物壁虎设计基于连杆的仿壁虎机器人结构,进行运动原理分析,对机构进行简化,以及自由度计算。设计相应的运动步态,选用对角线步态实现机器人的直线行走以及转弯动作。为简化机构并使运动柔顺,采用柔性杆作为仿壁虎机器人的身体连接件,通过对机构自由度的计算,分析机构的可行性,并结合静力学分析对柔性杆的选择进行讨论。在Adams软件环境下建立虚拟样机进行仿真和测量,对各关节的受力情况进行分析。通过实物样机爬行试验,验证了设计的有效性和可行性。

Abstract: A foot-type wall-climbing gecko robot using compliant shanks as body is designed, which uses dry adhesive to absorb. First of all, the structure of foot-type wall-climbing gecko robot based on link is designed by simulating biological gecko, the principle of movement and the degrees of freedom are analyzed, then the structure is simplified. Secondly the corresponding movement gait is designed, the diagonal gait is chosen to make the robot walk on straight line and turn around. Thirdly, to simplify the mechanism and make movement compliant, a compliant shank is used to connect the body parts, according to the calculation of degrees of freedom, the feasibility of mechanism is analyzed and a flat compliant shank is chosen on the basis of statics analysis. Lastly, by simulation using Adams and experiment with virtual machine, the force of every joint can be analyzed. Through making experiment by physical platform, analyzing the sample of the trajectory of robot crawling, the validity and feasibility of the design are verified.
