Abstract:
Moon - next location for human to be immigrated. Scientifically, moon is going to serve as a base for deep space networking, extra-galactic astronomy and Search for Extra Terrestrial Intelligence (SETI) in the forth coming decades. So it is necessary for us to get information about the features of moon. Here I’ve given a hypothetical situation of moon rover design and I did the design as per given requirements which is the Automated Multi-Conditional Exploration Rover (AMCER).

According to the allocated allowable dimensions the rover is designed. The rover is enclosed in a container of volume 0.1945 cubic meters and the total weight is subjected to 20kg. After proper docking from the space craft, the container is landed in the lunar surface. The rover is then driven out from the container in an automated way. The container serves as the base and makes a communication loop (AMCER ßàcontainerßà earth station). The moon rover is made to survive at all condition i.e. varying temperature range (-233°C to 123°C), hazardous radiation prone area etc. AMCER’s main chassis frame and the links are made of titanium alloy (Ti-6Al-4V). The remaining body is made of a special type of plastic, PVDF CN-F , thermally stable to 335° F. The main reason for using this, is the light weight of the material. The wheels are made of TEMPALUX CN-F and driven by 4 DC series brushless motors.

AMCER is designed into 3 pair of 6 wheel segment. All the main components including micro controller, communication device, scientific pay load, data storage etc. are placed on the middle segment. Batteries, material samples are fixed at the rear wheel segment. The manipulated robotic hand along with the high resolution camera and imager are at the front wheel segment. The special feature of AMCER is its segmented wheel arrangement. With this, AMCER can climb up to a height of 0.5meters, at an elevation of 50 degrees. Steep landing is also possible. There is no directional constraint in the AMCER locomotion, having all degrees of freedom. The power source is made available in two ways, radio isotope power (which also keep the warm during long lunar night) and rechargeable battery. The rover is capable of traversing a distance of 17 mile in a single EVA and the power will last for long lunar night. The power is distributed by electronic controls, which leads to power consumption.

The robotic manipulator of AMCER has 4 sensors and a image recording camera. They are mainly used to detect and locate the presence of HELIUM -3. The rover is provided with an obstacle detection and avoidance control. The scientific pay load include search for organic evidences and sample collection. The astrophotometer is attached to measure light levels. With all these peripherals AMCER can maintain its stability and maintain a 3.9 km/h speed through the duration of an eight hour traverse, sustain a 15 km/h sprint for one hour.
