This article discusses the design of a robotic agricultural machine for sowing crop seeds in a scattered manner, the scope of which includes various agricultural companies, agro-industrial complexes, as well as small farms engaged in sowing grain crops. Existing sowing machines have a general drawback, which consists in the fact that wet soil adheres to the surface of the working bodies, in particular the double-disc coulters of these machines, thereby changing the shape of the groove, forming a pre-sunflower hill, which is the reason for violating the requirements for sowing. These factors worsen the quality of the work performed, and there is an increase in traction resistance, which leads to increased fuel costs – lubricants. To solve this problem, the task was set to develop a robotic agricultural machine that will perform its functions automatically with minimal human participation. The design was carried out in a three-dimensional CAD – program Compas 3D V19. The article describes the device and operating principle of a robotic agricultural machine, including a description of the frame on which a control unit, a seed hopper, a seed tube with a damper, a belt drive, drives, a chain harrow, a disk spreader and a furrow-forming roller are installed. A design of a disk spreader with concave guides is proposed, which will ensure uniform distribution of seeds over the field surface. During its development, an exploratory research method was used, including the analysis of known disk spreaders. Existing approaches were used in the design and engineering of industrial robots.
