ROBOTIC ARM BASED EXCAVATOR CUM REGOLITH SAMPLING DEVICE · 模型 268385
**Update 2.3 (29/9/18)- Added the following files --- Top level assembly draft file that includes all required design dimensions ----Power budgeting graphical sheet in .jpg format shows the power required during one cycle of sampling ----technical document in .pdf format covering all important aspects about the design in detail. **Update 2.2 (27/9/18) - Added a motion simulation of sampling process of the device in .gif format and updated the Youtube link of motion simulations with the same. Added a weight budgeting of the device in .jpg format. This design is the second update of the design submitted around two weeks earlier. The basic concept is the same, except the use of MOS2 solid lubricant bearing for elevation pivot pin and use of needle thrust roller bearing along with the deep drawn needle roller bearings for azimuth. The sampling part of the design weighs around 150 gm and made of teflon. The extraction, elevation and azimuth drive along with its peripherals alone weigh around 500 gm. The weight is totally dependent on the height of the arm placed from the lunar surface on lunar descent module. The landing camera near the lander legs is considered for visual inspection of the sample and the animation on the following youtube link clarifies the working of the mechanism. https://youtu.be/6zgYAtWMufs Also to reduce the weight of the whole system, fasteners are all made of titanium as per ASTM B348 standards.
