Vertical Shaft/Cage Inspection for Rambler Mines, Canada

A significant complication of that mission was the continuous water pouring from above in all three cages thus we had to mitigate this issue by covering the cage of interest with a tarp. This reduced the water to about 50% of the quantity falling over the drone and the drone and all its systems proved to tolerate mild-rain-like precipitation.
