For agrarian economies such as India, the quality of the soil is critical for maximized yield sustainable cultivation. When a large area is utilized, sample testing of soil is essential. The use of a robotic system for sampling is vital for saving time and replacing manual laborious work. This work represents a robotic system that was deployed for soil sample collection. A mechanical soil sampling and storage system based on augers and turntable storage is used in the system. Using a GPS-driven algorithm, the robot navigates autonomously to desired sampling locations. It collects data from the sampling area using sensors connected to an Arduino board. A proof-of-concept demonstrator proved that such a solution can be successfully scaled and deployed, which will aid in more efficient cultivation and sustainable agriculture.

Because there are less restrictions in space, a variety of different movement patterns and equipment structures may be used during the process of planetary surface sampling. Traditionally, the optimal analysis for surface sampling is focused on specific equipment structures and movements; in contrast, a new modular motion-structure design model for surface sampling, which is a more flexible model, is discussed in this paper. By establishing and combining two basic module groups, namely, the motion group and the structure group, this new design model can define and analyse multiple movement patterns and structures. For the motion group, calculating the sampling trajectory is the main purpose, in which there are two basic modules: tridimensional uniform rectilinear movements and tridimensional uniform circular movements. The two basic motion modules can be freely combined in a given coordinate system to simulate a random sampling trajectory. The structure group contains a series of curved and flat plates, which can be defined by a set of unified parameters (including section, extension, and cutting parameters). By assigning different values to these parameters, the curved or flat plates can represent different external shapes. The different structures of the various pieces of surface sampling equipment can be simulated by combining these different plates. In addition to defining these basic modules, analysing the coupling among different modules, which can be simplified to the relationship between velocity and surface, plays an important role in establishing this design model. Based on the modular design theory, this new model will not only reduce the difficulty of analysis but also improve accuracy for planetary surface sampling.
