- W2783148779 abstract "The Moon is earth’s only natural satellite, it has no atmosphere, no life. The days are nearly burning, the nights are freezing. It is old and cratered, smooth and young. Yet, curiosity and desire to explore the uncertainty has driven man to find scientific truth. Here comes a small “Nano rover” from TU Delft! TU Delft, Netherlands and Indian Institute of Science, Bangalore, India are working towards an opportunity to land a space robot called “Nano Rover” on the Moon in collaboration with Indian Space Research Organisation (ISRO), Bangalore, India. The prime objective of the mission is that the rover should navigate on the Moon surface. The secondary objective is to capture photos intermittently and send the data to the earth. Considering the mass and time constraints, the existing terrestrial Zebro robot was proposed to be chosen for this purpose. However, Zebro is designed for terrestrial applications and it has to be adapted to the extreme environment conditions on the lunar surface and earth-moon transit orbit where the temperature can go as low as −180◦ C. Thus, it is quite challenging to modify the existing Zebro to suite the requirements for extra-terrestrial applications. Hence, a detailed study of lunar environment is necessary along with the extensive study on the adaptability of Zebro to be lunar compliant. This thesis presents (i) a literature study on the environment conditions on the Moon and during earth-moon transit orbit (ii) analysis of the existing Zebro and lists the requirements to adapt it to be lunar compliant (iii) conduct tests on materials, components and elements to enable usage of them for lunar and transit orbit environment (iv) design, develop and test the On Board Computer for lunar compatible Zebro and (v) demonstrate the locomotion of the robot on a simulated lunar terrain. There are three major challenges in conceptualizing and realizing the Nano Rover - (i) stringent mission management (ii) adapting it to the hostile environment such as temperature, vacuum, radiation, vibration, shock (iii) strict product assurance needs. This thesis has comprehensively addressed these challenges and successfully adapted the existing terrestrial Zebro as Nano Rover. Highly reliable electronic components were chosen, tested, and used them in designing the locomotion system. A lunar complaint On Board Computer and a motor drive system were successfully realized meeting all the lunar mission needs. The prototype was tested successfully under extreme simulated lunar environment conditions and locomotion on a simulated lunar terrain was successfully demonstrated." @default.
