According to the instruction from the host, the driving speed of the two wheels was adjusted to implement advancing, backing off, turning left and turning right. When the controlling unit receives the signal from colliding-switch, it can keep away from the obstacle according to the fixed programming.

Abstract: Fault diagnosis of PLC control system includes fault diagnosis of peripheral equipment, hardware and software of system. The block storehouse, interrupt storehouse and local storehouse can automatically create the state of each part by self-diagnosis of system. Fault causation and fault position of the system can be judged with programmer reading or writing state word and control word. By calling the state test, input or output signal, comparing memory, it can complete PLC self-diagnosis. Input switch, output pilot lamp is tested with direct test way, and the keyboard fault can be judged by inserting keyboard short circuit program in initialization program of system. The first fault can be tested through defining the symbol of first fault in the program.

Abstract: The close-loop structure was adopted in 5-coordinate machining robot, the host shaft was connected with a number of spatial connecting poles. Moving coordinate system is composed of cutting tool center and hinge joining parts of principal axis of cutting tool. Center coordinate of hinge joining point between control shaft and host shaft parts is calculated to determine machining posture of cutter. The azimuth of the host shaft was determined with A set of Eulerian angle (precession angle, nutation angle, self- rotation angle ). Corresponding to every posture of machining, the position of a certain part of the host shaft was calculated, and the position can made the lengths of the two control axes are instantaneous equal. The length of connecting poles was changed through servo motor to adjust posture of host shaft. So that if one of control ends of NC system controls two axes simultaneously, the function of the 6-coordinate system can be realized with 5-coordinate system.
