NASA-Lunar Sampling Unit-Revised. · 模型 85872
*Power consumption* Power is almost 4-8 W as Nema 14 stepper is used for auger probe and reciprocating mechanism. Chain mechanism gets power from Rover. *Material* Parts are made of aluminium for chain (carry the regolith), hopper (collects sample), Auger probe (drills sample), whereas Teflon for cylinder covers Auger Probe. Remaining could be assigned as plastic since they are light weight and does not have to suffer much stress under operation in space. *BOM* | 1 | Power Wheel | 1 | Shaft | 2 | Sprocket | 1 | Base Sketch | 18 | Adding Link | 18 | Connecting Link | 1 | Chain Connector | 1 | Sample Container | 1 | Hopper | 1 | Conveyer Tube | 1 | Auger Probe | 1 | Nema14 26mm | 1 | Bevel Pinion | 1 | Bevel Driven | 1 | Gear Shaft | 1 | Gear 20T | 1 | Rack Gear 10T | 1 | Ball Bearing 1'' | 1 | Base *Parts to be added* 2 x Limit sensor one at 4.5 cm from base and other at top. *Working* First base(green) are fixed to rover and power wheel (red) is dipped onto moon surface. Once the rover starts moving, surface rocks are collected and collected in container through hopper. When the limit sensor detects the filling of rock, rover is made to stop. Now, Nema stepper motor is made to start by programming Ardurino board. The mechanism for moving 10 cm deep has been modeled and was referenced from https://grabcad.com/library/reciprocate-gear-mechanism-1. Now the auger probe digs through regolith and collect sample which then transferred to transferring tube finally to container. When it is fully filled, sensor senses the block and Nema stepper motor stops. Also container can be easily removed by rotating in counter clockwise as it is designed like flip-flop mechanism. *Lander Component* Lander component to be used as Lunar excursion module or any kind of rover used in Apollo space mission. *Credits* https://grabcad.com/trinityscsp https://grabcad.com/nemanja.petkov-4 *Note* For good clarity of understanding, images has been attached naming 1.png to 7.png
