Water tank selection
Rover weight capacity 35 kilo grams (payload)
Rover measurements:
Wheel distance - 14.5 inches and 8.5 inches
Rover platform size (width & length) 14.4 inches x 10.4 inches
Height- 15.8 inches
Water tank selection
More or less 25 liters
*For tank selection we need to justify the size with the center of gravity, proving that is the
maximum dimension or liters of the tank because the center of gravity will be higher making
the rover prone to toppling
Pump selection
*Our sprayer design has two nozzles which splits using a tee splitter, we need to find the
size of the pump to obtain the same discharge rate of a normal sprayer. A normal sprayer
has a 12V pump and a pressure from 0.2 to 0.45 mpa (30-65 psi)
The application rate of the main pesticide is 9.6 - 19.2 fl oz/A (Brigade Insecticide for sweet
potato)
Thai was the initial deign where the water tank is above the battery and pump, but we
changed our mind, now it is the battery and pump above the water
Battery selection
* once the size of the pump has been selected what battery should be used for that pump.
Commonly a knapsack sprayer has a 16 liters tank, 12v pump, pressure from 0.2 to 0.45
mpa (30-65 psi)
