WHAT IS SPACE ROBOTICS?

Space robotics is the development of general purpose machines that are capable of surviving in the space environment, performing exploration , construction, maintenance, servicing or other tasks. Humans control space robots from either a “local” control console or “remotely” controlled from human operators on Earth. Space robots are generally designed to do multiple tasks.

“Local” control Spacecraft Arm Remotely controlled Space Robot “Mars Rover”

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 Space Robots?!

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.

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.

ISSUES IN SPACE ROBOTICS There are four key issues in Space Robotics. These are:

Mobility—moving quickly and accurately between two points without putting the robots, astronauts at risk.

Manipulation—using arms and hands to contact worksite elements safely, quickly, and accurately’

Time Delay—allowing a distant human to effectively command the robot to do useful work.

Extreme Environments—operating despite intense heat or cold, ionizing radiation, hard vacuum etc

How Robots Work in Space Working principle of Space robots are based

on the SPA algorithm. SPA stands for sense, plan and action. It is used in built world modules to match and worked accordingly.

New Generation Space Robots The new generation of system is called as

probabilistic robots , which are under development and research.

The Main Working Principle of new generation robots are very simple & quick. Some bots have AI(artificial intelligence). These types of bots can make their own decision when needed.

Technologies Used

Mapping and navigationOne 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 Space Robots

There are 4 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

Probes

A similar class of robots explores the solar system without actually physically landing anywhere. These typically use cameras and a variety of instruments to measure conditions on other planets, moons, and the sun from some distance. Most of these use solar cells to power their instruments.

Astronaut Assistance

Besides acting as explorers, space robots can also assist astronauts in manned spaceflight. One of the most notable examples is a device known as the Canadarm. Developed with funding from the Canadian Space Agency, the Candarm became a permanent fixture on many American space shuttles and the international space station

Recent Missions

Voyager 1Launched on 5 September 1977. Jupiter and Saturn flybys. It escaped from the solar system and is still transmitting useful data.

Mars express Launched on 7th June 2003 and

reached Mars on 25 December 2003

Future MissionsExomars

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.

Robonaut

Robonaut is an "astronaut-equivalent“ ,highly dexterous robot under development that will use all the same tools, handholds, and other equipment that astronauts in space suits can use.

It can be perform as an assistant in collaboration

with suited astronauts.
