The weird cocktail of human curiosity and exhaustion of minerals, over population has led man to explore the unexplored areas and this is what is called as space research As told earlier, space is full of unexpected probabilities and it is a challenge to explore and research about space with minimal loss of expenditure and human life. Space travel has always been dangerous and any unexpected event can cause death.Why Robots?? : Why Robots?? Expensive and dangerous extra vehicular activities can be reduced. Dangerous environment can be tolerated They can work efficiently in a hostile, non-terrestrial environment. Planetary surfaces can be explored more cheaply and quickly.BASIC WORKING PRINCIPLE: 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. The sensors provide information about the surroundings. The controller process the information along with the instruction radioed from the earth sends commands to the actuators convert signals into actions and robot perform its function.SHAKEY (1966-1972): 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. The major disadvantage was that it was very slow and could not encounter unexpected situations.SUBSUMTION ROBOTS (1986-??): SUBSUMTION ROBOTS (1986-??) It requires no internal world models as it is based on instinct and it makes the world its own model. It is very fast and alive.HYBRID SYSTEMS (2000-??): HYBRID SYSTEMS (2000-??) This system made the robots both reactive and deliberative. It was a combination of previous two systems so we can tell that it was both instinctive as well as well structured.Obstacle avoidance and Mapping: Obstacle avoidance and Mapping Various instruments used are Sonar sensors Certainty grids Laser sensors Mappings are Topological mapping Geometric mapping Path planningKey technologies used:: Key technologies used: Mapping and navigation Obstacle avoidance Mapping Path planning Computer vision Stereo vision Color vision ArchitectureStereo vision: Stereo vision This technology is an upgrade of geometrical mapping technology. It is similar to that of human eyes, a robot has two cameras at a fixed distance on straight line; the robot uses these different perspectives of two cameras to find the exact distance. Distance=baseline*focal length/(x1-x2) Where, X1=distance of the object from the first camera. X2=distance of the object from the second camera.Color vision: Color vision This technology mainly consists of primary colour components and it is used to recognize objects by knowing the characteristics of an object. For multiple colors, histograms are used.Architectures: Architectures It comprises of 3 technologies. 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: Types of robots in space Planetary Rovers IN-orbit Operators : Future Applications :Under Research Mineralogy and robots: Under Research Mineralogy and robots Under research Robonaut: EVA robotic assistant : Antarctica: Mineralogy and robots Voyager 1 Mars express Mars rover Phoenix mars scout Change 1 ChandrayanFuture missions: Future missions Exomars Due to be launched in 2015. It will characterize the biological environment on mars, using a descent module and rover, in preparation for subsequent robotic and human exploration.Conclusion: Conclusion We can conclude after all the research that the field of robotics has made serious and positive inroads in the field of space exploration. The various technologies used in robots have made space research cost effective and efficient also. The human mind has created and is creating brilliant technologies, which has made space research as a field to reckon with and simultaneously helped in a huge advancement in the field of robotics.Vote of thanks : Vote of thanksQueries ??: Queries ??
