“…The system that performs this operation for a single row is called the sowing unit. 28 The spacing of these units on the chassis should be adjustable for different crop plantings. Furthermore, the planter machine should not apply a high pressure to the ground in the cultivation areas.…”

The application of X-section beams in the modular and strength-based design of a precision planter chassis was investigated numerically and experimentally in a case study. This study deals with the feasibility of a special section design with a systematic engineering approach. Mechanical tests were performed for the beam evaluated in a mounting system. The X-section beam model and the mounting elements on this beam were created using computer-aided engineering software, and the compatibility of the design with the mass criterion was investigated. This model was edited as a 2D and 3D mixed model and analyzed with the finite element method to analyzing studies of the system. Stress measurement was conducted using strain gauges at specified points in the system whose prototype was produced. These strain data were processed with nCode DesignLife software, and nonlinear FEA analyses were validated using these stress measurements. The fatigue damage of the X-section beam under dynamic loading conditions was investigated using the FE model solution and experimental measurement data (CAE-based fatigue analysis) with nCode software. The X-section beam design adopted a multiple-objective genetic algorithm technique for optimization by means of ANSYS. The maximum stress value was 121.83 MPa, and a 7.77 kg material was saved correlated to the prototype with the help of optimization solved 400 iterations. It has been determined that the X-section beam is safe by 1.06 × 106 cycles under these loading conditions and can carry a load of 1600 kg. The X-section beam can be successfully applied in similar systems owing to its assemblability and functionality.

“…Of the three tasks, sowing of one individual seed has not been realized, especially in a dense plant environment [32][33][34][35][36]. The ideal farm conditions for Synecoculture are those where the topsoil is not exposed, and various vegetation is always overgrown.…”

Currently, an agricultural method called SynecocultureTM has been receiving attention as a means for multiple crop production and recovering from environmental degradation; it helps in regreening the environment and establishing an augmented ecosystem with high biodiversity. In this method, several types of plants are grown densely, and their management relies mainly on manual labor, since conventional agricultural machines and robots cannot be applied in complex vegetation. To improve work efficiency and boost regreening by scaling-up Synecoculture, we developed a robot that can sow, prune, and harvest in dense and diverse vegetation that grows under solar panels, towards the achievement of compatibility between food and energy production on a large scale. We adopted a four-wheel mechanism with sufficient ability to move on uneven terrain, and a two orthogonal axes mechanism with adjusted tool positioning while performing management tasks. In the field experiment, the robot could move straight on shelving slopes and overcome obstacles, such as small steps and weeds, and succeeded in harvesting and weeding with human operation, using the tool maneuver mechanism based on the recognition of the field situation through camera image.
