Mass of whole system = 0.41528 kg (without Nema 8 Stepper motors (3)); 0.61021 kg (with Nema 8 Stepper motors (3));Total power consumption of each Nema motor is 2.34 W in total 7.02 W.Samples are packed by layering through filtering samples on each stage thus can be collected easily.Camera view image has been attached.*BOM*| 1 | Base | 1 | Auger Probe | 2 | Bevel Gear 18 T | 1 | Gear 20 T | 1 | Rack Gear 10 T | 3 | Nema 8 Stepper Motor | 1 | Sample Collector | 1 | Ball Bearing | 1 | Nema Support | 1 | Roller | 1 | Lock Pin | 1 | Container | 1 | 2 cm to 1.5 cm Filter| 1 | 1.5 cm to 1 cm Filter| 1 | 5 mm to 1 mm Filter| 1 | 1 cm to 50 mm Filter| 1 | Helical Conveyor | 1 | Vibrate Connector | 1 | Vibrate Crank | 1 | Vibrate Lock Pin | 1 | Battery *Material Designation*All part model are made out of polystyrene except auger probe, helical conveyor, bearing, sample collector, cylindrical tank, filters. As polystyrene is stronger and moreover has no hard jobs on moon.*Filters*There are four filters which vibrate due to slider crank mechanism. Filter sizes are 2 cm to 1.5 cm, 1.5 cm to 1 cm, 1 cm to 5 mm, 5 mm to 1 mm.*Working*First due to reciprocating mechanism of gear arrangement as found on Reciprocate Gear Mechanism this gives 10 cm reciprocating motion to auger probe. It collects the specimen and bearing with special teeth which match the auger probe puts the specimen into the rectangular box and thus conveyed to cylinder container of 4.8 cm diameter and 5.73 cm tall. The filter gets agitated continuously by slider crank mechanism and stored in layers of sample.*Lander Component*Lander Component can be used as Lunar excursion module.*Advantage*1.Able to work continuously at any pressure difference because there is no use of vacuum devices.2. The sampling will be done within 0.5 earth day.3. Multiple sampling locations can be done on moon without affecting the sample content.4. Almost 88% of power saving.
