Moving on the to the possible non-NASA commercial application it can be said that the same qualities of the LPE that apply to space would also attract terrestrial users or said differently us earth bound creatures. As both business and government markets rapidly expand so does the need for urban infrastructure. Using NASAs own words on the subject; Urban construction settings restrict the use of explosives to minimize damaging vibrations making mechanical methods attractive. In addition shallow tunnel construction is rapidly changing from cut-and-cover to wholly underground because excavations disrupt city traffic. Coupled with increasing population these factors enhance the market for innovatively flexible systems such as the LPE. If I could have said it better than NASA did I would have. But I couldnt so I didnt. Anyway there you have it both the past of excavators and a look at their future with the development of the Low-energy Planetary Excavator
These excavators can vary on the basis of their usage because there are different users for these excavators. The excavators can expand their uses when aided by different attachments. A flexible and successful excavator can be ensured by using standard mini excavator couplers. This would ensure a smooth functioning because all the attachments will work right the first time. Being the most popular equipments in the construction industry excavators have successfully aided in reducing the involvement of human effort in heavy construction work.
Excavator Arm: The arm is attached to the lower part of the frame chassis and has two main sections that are joined with a hinge. The sections have pistons that move them. When the first piston extends the rod pushes against the arm and raises it thus extending the section. The second arm then contracts and expands thus raising and lowering the second section. To help the excavator to scoop and dig the arm has a bucket loader. Tracks They are rigid and fixed in one place. The tracks are stationed around a series of gears that turn after receiving power from the drive shaft that is connected to the engine. When the tracks are in gear they roll the excavator backward and forward in a straight line.
Basically The LPE would be a general-purpose machine with the ability to mine ice regolith and rock; it would also support construction activities. The purpose and application is meant for future manned and unmanned missions to the Moon Mars and beyond. .Additionally adaptations could be made for use in extreme-low gravity such as on asteroids. This idea of efficient and reliable an excavator that has usage on differing planetary surfaces and various materials has the goal of enabling exploration and bases from outposts to self-sustaining complexes. The LPE would be able to accommodate the different materials that are encountered on planetary surfaces as the LPE would sense geologic changes and respond to them by using the lowest cutting energy possible.
