SPACE ROBOT

AUTOMATIC BRAKING SYSTEM

INTRODUCTION:

FIRST VERSION:

I HAVE STARTED MY PROJECT BY MAKING AN AUTOMATIC BRAKING SYSTEM IN VEHICLE . I MADE THIS BECAUSE , IN INDIA FOR EVERY FOUR MINUTES AN ACCIDENT OCCURS . COMPARING TO THE DEATH CAUSED IN THE FIELD OF ARMY , THE DEATH CAUSED DUE TO ACCIDENTS IS HIGH . WE CANNOT STOP THE ACCIDENTS COMPLETELY BUT WE CAN REDUCE ACCIDENTS. SO I MADE THIS MODULE .

APPLICATION :

THIS MODULE IS FIXED WITH THREE INFRARED SENSORS , WHICH DETECTS THE VEHICLE WHICH COMES TO HITS . THEN IT WILL AUTOMATICALLY APPLY THE BRAKE . SO WE CAN REDUCE THE ACCIDENTS . IN REAL LIFE WE CAN FIX PROXiMITY SENSORS FOR 360 DEGREE SENSING . THIS CAN BE FIXED IN ALL VEHICLES

HOW CAN WE FIX IT IN ALL VEHICLES :

After 8 years every fuel car will be converted into battery car. At that time we can fix this module also

· After applying brake it will set a new path . so that the driver can control the vehicle , as the car would turn right , or left , as the sensors have been fixed on the side of the vehicle also .

CLE . THIS CAN BE IMPLEMENTED IN CHANDRAYAAN 3 ALSO

A HIGH TECH SPACE ROBOT

CURRENT VERSION :

THIS PROJECT GAVE ME SUCCESS . SO I PLANNED TO UPDATE THE PROJECT . WHILE THINKING ABOUT THAT AN INCIDENT STRIKED MY MIND . ON 2018 NASA HAVE SENT A ROBOT TO MARS . IT GOT STRUCK ON THE MUD , AT MARS , AND IT GOT FAILURE . THE ANOTHER INCIDENT WAS , THE CHANDRAYAN 1 . THE SIGNAL WAS LOST WITHIN 8 MINUTES , AND IT RESULTED IN FAILURE . SO I HAVE USED RASPBERRY PI , TO CONTROL THE ROBOT USING PC (node – js ) .

MATERIALS USED :

· INFRARED SENSOR (VERSION - 2)

· ARDUINO UNO R3

· GYROSCOPE (ADXL 335 ANGLE SENSOR)

· MOTOR DRIVER

· RASPBERRY PI 0 (PIN 11 AND 13)

APPLICATION :

even if the control is lost , The robot will automatically , AVOIDES the obstacle and apply brake , and then sets a new path by its own . I have also fixed a lidar sensor and gyroscope sensor in that , so that it will measure the angle to avoid collision . I have fixed a camera IN THIS , so that it can send the images and videos to earth .

This can be used in chandrayaan 3 so that we can avoid these critical situation .

This idea can also be implemented in robots and satellites , to avoid THE obstacles. Normally every satellite can Be given command only after 8 minUTES. within this period any obstacle can hit this satellite . so to avoid this i AM implementing this module in satellite and robot which can avoid the interrupt occurring if there is no signal in space .

SCIENTIFIC PRINCIPLES :

The scientific principles involved in obstacle avoidance is depends on infrared sensor . it emits infrared rays and it gets reflected to the ir sensor . if the sensor detects the object at right side the right side motor will rotate forward and left side motor rotates backward . . if the sensor detects the object at left side the left side motor will rotate forward and right side motor rotates backward . if the sensor detects object at front it will automatically applies brake .

SOFTWARE USED :

} ARDUINO IDE

} RASPBIAN JESI ( LINUX DEBIAN OS )

} NODE – RED ( BY NODE JS )

PUTTY

FUNCTION OF THIS PROJECT IN SPACE

I WILL SHOW YOU HOW I AM CONNECTING PC AND RASPBERRY PI . The module is controlled wirelessly from pc using putty software. IP address is needed to control the robot from its host or shell of the processor. When connection between module and pc is established then switch on the node red server. In search engine type the given ip address with the port number . in microcontroller the code is uploaded . while controlling if any interrupt occurs , it is avoided by this ir sensor. The readings are read from the , node red using debugging node . SO I THINK THIS PROJECT WILL GIVE SUCCESS FOR OUR SOCIETY .

FUTURE IDEA :

I AM GOING TO ADD LIDAR SENSOR TO THIS MODULE SO THAT it measures distance to a target , by illuminating the target with laser light , and measuring the reflected light with a sensor.

Why I use lidar : ( Light Detection and Ranging )

· LIDAR is used to measure the surface of the earth . Lidar sensor senses the object at 360’ . it also makes decision by its own . lidar sensor detects by using light waves instead of radio waves . this is one of the advantage of LIDAR .

· ON 2020 , MARS IS GOING TO LAUNCH A ROVER MARS 2020 . IN THAT THE ROVER WAS FULLY MADE UP OF SILICON WHICH IS VERY FLEXIBLE . SO EVENTHOUGH IF COLLISION OCCURS THERE WOULD BE NO DAMAGE TO THE VEHICLE . THIS CAN BE IMPLEMENTED IN CHANDRAYAAN 3 ALSO

IT INCLUDES THE CURRENT NEED AND ITS SOLUTION AND NEW VERSION OF MY ROBOT
