Evaluation of the Stability Behavior of an Agricultural Unmanned Ground Vehicle

Precision farming is the newest agricultural approach in countries with highly mechanized field operations, and role of unmanned ground vehicles (UGVs) smart becoming increasingly prominent. This work aimed to evaluate stability DEDALO UGV developed by University BOLOGNA for precision orchard vineyard management. The driving part machine somewhat peculiar; it moves autonomously combined a tank store water pesticide mixture crop protection, an additional structure carry implements. study unladen UGV, mulcher sprayer mounted configurations. In case sprayer, behavior was evaluated empty full tank. machine, terms stability, studied both laterally longitudinally. A theoretical model based on upstream side forces measured during experimental tipping tests. results data were compared predicted validate model. lateral test, average value limit angle 48 degrees, while longitudinal 49 degrees. statistically correlative (R2 > 95) denoted that most stable condition occurred fitted position (56 degrees), unstable (40 degrees). Although problem not directly connected operator, as these machines do require driver, lack can lead overturning consequent risks surrounding environment damage body.
