Abstract
In the paper, we consider relevance of autonomous mobile robotic system (AMRS) for coastal zones monitoring development. AMRS developed in Nizhny Novgorod State Technical University n.a. R.E. Alekseev is presented. General chassis characteristics are provided. The paper establishes four indicators of mobile chassis power efficiency: tractive force reserve under various operating conditions, tractive force for the certain probability of all soil surfaces, fuel consumption efficiency per 100 km, and the same indicator related to the carried load mass unit. Calculations based on the abovementioned indicators are made for 6x6 chassis, and for the track mover modification. The results show that on sand-gravel and sand roads power efficiency of wheeled chassis is 17-18% higher.
