In the servo driving system of the robot, expensive servo motors are replaced by common direct motors and magnetic encoder. Finally, the closed loop control of motors are successful realized.
For the magnetic-sensing resistor transducer: magnetic ink pattern recognizing transducer, gear transducer, magnetic encoder, Linear displacement transducer and Contactless magnetic-sensing resistor potentiometer etc. The working principle, structure, the main technical feature and their applications are also presented respectively.
TMS320LF2407A DSP makes up of the core of the servo controller. It implements the operation of the timing and the comparing, the controlling of the speed and position, the communication with the identifying and orientation system of beacon, the communication of the host, and the operation of I/O scanning algorithm.
Based on the working conditions of the drilling robot, the author analyzes and compares the revolving photoelectric encorder, revolving inductosym and magnetism encorder which are used as an angle sensor of the drilling robot control system respectively, and discusses some questions which selection and application of them involve in.
Insb magnetic-sensing resistor element and magnetic-sensing resistor transducer are the main, new rinds of the magnetic -sensing and transducer. The first, their working principle, structure and property etc are briefly introduced respectively.
