Ultrasonic Imaging Sensor (Mechanical)

Brief Description

Imaging system developed at CSIO makes use of ultrasonic ranging module to find the range of the object continuously as the robot scans it mechanically. 40 KHz ultrasonic transducers have been integrated with the gripper of PUMA 560 robot. The controller of Robot has been interfaced with the range module. The range values calculated by 8085 microcomputer of Ranging System are received by the robot controller. A VAL program operates over these values to decide the next motion of robot arm which is made to move in cartesian co-ordinate system. These range values are also simultaneously received by a Personal Computer (PC) which does the calculations for object perimeter, area, centre of gravity and orientation in TURBO-C. These parameters are finally passed on to the robot controller so that robot can grasp the object at correct orientation. The image of the object is displayed on PC screen for viewing information.
