NASA Lunar Sampling System Design ChallengeFull detailed model is designed with overall weight 690 grams with motors (Without container and electronics box) Model structure are made of aluminum sheet metal 2 mm thickness. They could be cut using small laser machine or water jet. A manual sheet metal bending machine used to make all structure parts easily. All sheet metal part are supposed to be welded together Three stepper motors Nema 8 ,weight 60 gram ,rating Current 0.6 A, rating Voltages 3.9 V, Holding torque 1.8 N.Cm. Arduino could be used as motors controller.SQ11 HD night vision camera is recommendedTwo Videos are attached, the first one illustrate assembly steps of all parts. Second video demonstate the movement of model.Solidworks models 2018 are available upon requestTwo Stage filtering have been add to collect the required range of rock's sizes. the 1st stage in the shovel where it allow small sizes to disposed (less than 8mm) and 2nd stage in the filter which prevent big rock from collecting in the container (bigger than 20 mm)Shovel and filter holes can be resized according to desired sizeRover design is capable of move forward and backward and turn through breaking single wheel's motor and rotating the other
