Robots play a vital role in exploring the hostile environment of outer space. Besides the Earth, the Moon is the only celestial body that humans have stepped on. However, advancements in research are making it possible for robotic missions to reach space faster and gather more information than humans. Robots don’t get tired, can operate in airless environment and do not get bored or distracted, making them superior to humans in a lot of ways. In general, all space robots have the same components that include a power supply, controller, actuators, sensors and radio communication unit. These sensors collect information about the robot and its environment, the controller processes the information and control instructions, and transmits the command signals to the actuators. The actuators in turn convert the signals and execute the operation. Autonomous robots are operated independently as the long transmission ranges of radio waves prevent the remote control of such robots in real-time. Rovers that encounter craters, cliffs, rocks and other dangers are operated based on this concept.
