ADAMS ENGINEERING COLLEGE PALVANCHA PAPER PRESENTATION ON SPACE ROBOTICS BY SATHYA MADDUKURI • SPACE ROBOTICS • CONTENTS:  INTRODUCTION  BASIC WORKING PRINCIPLE  TECHNOLOGY  TYPES OF BOTS  FUTURE MISSION  CONCLUSION • INTRODUCTION:  The space environment represents one of the most challenging applications of robotics.  Robotics is a field that has been magnified by its association to space research.  The most important thing to note is that the scale of success in space systems is same as that for biological systems i.e., “SURVIVAL OFTHE FITTEST” • What is space research?  “SPACE”, the word itself signifies something infinite.

 Space travel has always been dangerous and any unexpected event can cause death.  It is here that the robots play a huge role and help mankind in his research process. • WHY ROBOTS?  They can work efficiently in a hostile, non- terrestrial environment.  Planetary surfaces can be explored more cheaply and quickly.  Expensive and dangerous extra vehicular activities can be reduced.

• BASIC WORKING PRINCIPLE  A Robot is a collection of controllers, sensors, actuators; radio communication and power supply and each of them are powered by various software’s. • Evolution of robots  SHAKEY (1966-1972):  It is based on the SPA (sense, plan and action) algorithm. It is used in built world modules to match and worked accordingly.  FLOW CHART: • HYBRID SYSTEMS (2000-??)  FLOW CHART:  The next generation of system is called as probabilistic robots, which are under development and research. • key technologies used:  Mapping and navigation  One of the basic functions of a space robot is to navigate its way cleverly through all obstacles that come in its way.

Mapping and navigation comprise of three more technologies  Obstacle avoidance  Mapping  Path planning •  Planning: It is a feature by which a robot understands the situation and decides a strategy to tackle it.  Sequencing: Selection of a particular skill set which would result in perfect execution of a plan.

 Control: Performing the selected skill set to perfection. • Types of Robots in space:  There are 3 basic types of robots in space and all the robots sent to space come under these types only.  Planetary Rovers:  It is the most advanced form of robotics technology used in space research.They are the robots, which explore, navigate and research themselves with the least human intervention; they analyze the data collected and send the results back to earth. •  IN-orbit Operators:  They are the robots, which assist an astronaut during his space mission. For example a robot can be designed specially to refuel a shuttle thus helping the astronaut to remain in his shuttle and accomplish various tasks without any risk to their lives • Mineralogy and robots:  Presently humans are facing a huge challenge of exhaustion minerals due to which space exploration is being used specifically for mineralogical purposes  It allows the robot to detect rocks and get precise spectral measurements and validate the data without any human intervention. • Current missions:  Voyager 1 Launched on 5 September 1977. Jupiter and Saturn flybys.
