Abstract

IN THIS PAPER, STRUCTURE OF IDAS CANSAT THAT HAS BEEN DESIGNED, CONSTRUCTED AND TESTED IN IUST, IS PRESENTED. THIS PAPER INCLUDES A DESCRIPTION OF CANSAT MISSION, DESIGN OF MECHANICAL SUBSYSTEM, ELECTRONIC CIRCUITS, AND ALSO AN ANALYSIS OF PERFORMANCE ALGORITHMS. ONE OF THE SPECIAL FEATURES OF IDAS IS ITS VERY LIGHT WEIGHT IN COMPARISON WITH OTHER CONGENERS. THIS FEATURE LEADS TO A RELATIVELY COMPLEX DESIGN FOR MECHANICAL SUBSYSTEMS INCLUDING STRUCTURE, REACTION WHEEL AND PARACHUTE. A COMBINATION OF FREEWHEELING AND BALLS AND BOWL IDEAS HAS BEEN USED TO CONNECT THE PARACHUTE TO THE CANSAT STRUCTURE. THIS JOINT KEEPS THE CANSAT MOVEMENT PERPENDICULAR TO THE GROUND. THE PARACHUTE HAS BEEN DESIGNED FOR HIGH SAFETY MARGIN (IN WEIGHT AND SPEED), TO SATISFY THE EXPECTATIONS OF STABILITY ALONG WITH THE REACTION WHEEL. WITH THE STABILITY RESULTED, IMAGING WAS DONE WITHOUT ANY MECHANICAL DISTURBANCES AND WITH HIGH QUALITY. IN THE ELECTRONIC SUBSYSTEM, WE HAVE USED AN ARM MICROCONTROLLER TO CONTROL THE CAMERA. CAMERA’S DATA, DUE TO THEIR HIGH VOLUME, WERE STORED ON SD CARD AND SENT TO GROUND STATION IF NECESSARY. AS THE MICROCONTROLLER OPERATES IN HIGH CLOCK FREQUENCY, IT OFFERS CANSAT COMPLEX AND VARIED OPERATIONALLY SUCH AS RELEASE DETECTION AND DATA HANDLING. RELEASE DETECTION ALGORITHM IS SENSITIVE TO CANSAT ACCELERATION. THIS IS A NEW APPROACH AND REDUCES THE PROBABILITY OF FAULTY DETECTION. AFTER RELEASE, CANSAT TRIES TO ACHIEVE ITS GOAL AND TAKE PICTURES FROM GROUND WHILE READING, STORING AND SENDING THE SENSORS DATA TO THE GROUND STATION. TO VERIFY THESE FUNCTIONS, WE IMPLEMENTED SEVERAL TESTS AND EXPERIMENTS.
