To deal with the traditonal problem of the low precision and automation, a photoing robot test system with a CCD camera,is given in this paper. The robot system is pided into many modules,including the main,the walking mechanism,the driving mechanism,the transmission mechanism and the reducing mechanism.This paper designs a cylindrical robot refering to characteristics of general pipe robots.The robot controls the step motor to rotate with SCM.And the robot realizes the functions of positioning,stopping and walking by transforming the movement from the worm mechanism and synchronous belt wheel mechanism to the wheel accurately and steadily.In addition,the screw mechanism can make structure meet different diameters of bore;"three jaw centering" mechanism support the consistency of the robot’s and bore’s barrel axis which can assure the photoing quality;the flexible adjustment mechanism prevent stucking even meeting some special casees. This paper used three-dimensional software Pro/E to get the inpidual components.According to the simulation results,the robot is modified to prevent the interference.In the end,the whole assembly model is given.After that,this paper uses the solid element and shell element to analyses the static characteristics of robot structure by finite element analysis software.Then we give some advise to de structure.
