Located in the central robot as a mobile platform can be loaded with control dc power supply and various related equipment, used to finish all kinds of particular task, in the motion process generally keep level. On both sides of the frame is based on a parallelogram structure deformation of the crawler module, mainly by the four connecting rod deformation institutions, the drive wheels, passive round and round the track of the wheel track composition, four of them deformation mechanism of connecting rod, connecting active and passive crank crank up, used to provide a driving force,And can be rotated around the frame, realizing track deformation, the obstacle to provide additional auxiliary motion robot. The robot has 3 degrees of freedom, namely a translational degrees of freedom and two rotational degrees of freedom. Mounted on a robot two main driving wheel motor through the coupling drive, the main drive wheel rotation motion into translational motion track of the robot, straight forward, backward and steering. A motor is mounted on the frame, through the chain transmission drive around both sides of track deformation module of the driving crank around the rack is located in front of the axis of rotation, thus realizing the four connecting rod mechanism of deformation, eventually winding around the track configuration changes. The structure is characterized in that the clever use of four bar linkage mechanism can make the robot traveling and track deformation, so that the robot has good barrier properties and ground adaptability.Key words: parallelogram Four connecting rod deformation caterpillar robot The obstacles河南理工大學(xué)萬方科技學(xué)院本科畢業(yè)論文II
