"This is my lunar rover called W.R.O.L.S(water research on lunar surface). W.R.O.L.S explores the lunar surface for past and present signs of water. If and when it finds signs of water it immediately memorizes its path for astronauts and future rovers to explore. My rover uses CRISM or compact reconnaissance imaging spectrometer for mars but I have made it CRISL (L for luna). CRISL uses detectors that see invisible, infrared and near-infrared wavelengths to map the kind of mineral residue that appears where water once existed. W.R.O.L.S runs on solar panels on its outside. The other sensors that W.R.O.L.S has are proximity, CRISL, moisture, image, optics and GPS. My rover has to decide whether the land it is approaching is level enough to go on. If it senses that the ground is smooth it continues or vice versa. This is my rover."
