This pool-side, battery-powered, device pumps water into internal test tubes for pH and chlorine testing. Then the corresponding chemicals, at precise amounts, are added to the test tubes which produce a color for sensors to read and output the current pH and chlorine levels.

This battery-powered robot detects snowfall and starts plowing away the light snow to avoid heavy accumulation. The machine is equipped with bump detection to activate the plow lift motor for the robot to pass over the obstacles and the tank-like tracks will allow for traversing the bumpy grounds.
