Top dropper

The design of this bucket drum is pretty simple. Unlike the baffle design in rassor 1.0, 1.5 and 2.0, this one excavates the regolith with the sCOOPER and drops it from the top into a collecting drum. To dump regolith, the collecting drum can be rotated upside down which can be controlled by an electromagnetic clamp. The electromagnetic clamp consists of a permanent magnet (AlNiCo, specifically LNG52), 2 electromagnets ( stronger than the permanent magnet, can be superconducting magnets depending on where the mission is planned) , and 2 iron pins (can be anything hard enough to not break under pressure and can be attracted to magnets). HOW IT WORKS: When the electromagnets are activated, the iron pins move from under the collecting drum shaft (rest position) held in place by the permanent magnet, to between sCOOPER shaft and collecting drum shaft, locking them both. Now the collecting drum can be rotated using the same motor that sCOOPER uses. Also it is designed in such a way that there are only two orientations for collecting drum slot, i.e. facing upwards or downwards, increasing its stability in low gravity conditions. Its design drawing is attached (Just for representation, not to scale) Top Dropper also has a dust shield, made of carbon fibre frame and mylar screen, to keep the working environment dust free. The design minimizes the rising dust and pushes all of the dust coming from the inside downwards. This means unlike the preceding designs of rassor, this one doesn't have to go 100 feet away from the unloading point just to keep the solar panels clean. This can also push the service date of the rassor longer. Also extra information is included in the comments of parts attached. NOTE TO JURY: It follows all the rules. It weighs less than 5KG (4.4 KG) Its capacity is more than 17.6 Lt At any point of time the max width of scoops engaging is less than 175mm Fill ratio is over 50% Meets the dimension requirements.
