Abstract
The wheat precision seeding technology provided an advanced agricultural support for the high yield of wheat. But the lack of effective agricultural machine made this technique difficult to apply widely. In this paper a wheel mobile robot to achieve the wheat precision seeding technology was designed. The kinematic model of the robot was built and simulated. And experimental study was taken under different operating conditions. Because of multiple effort factors, a quadratic orthogonal rotation combination design method was applied in the experiments, identifying the main factors by analysis. Then the field test was carried out according to the main factors. The experiment results showed that the qualified rates of seeding exceed 93% in different sowing speed. That reached the agronomic requirements of wheat precision seeding.
Highlights
With the development of agriculture in China, the traditional intensive and meticulous farming had been unable to meet the requirements of current agriculture and agronomy development
Using agricultural machinery instead of the traditional manpower had become a major trend in the world [1, 2]
Japan, the United States, and other countries were in the lead [5, 6]
Summary
With the development of agriculture in China, the traditional intensive and meticulous farming had been unable to meet the requirements of current agriculture and agronomy development. The agricultural robot had become an important target in research and development of agricultural machinery engineering [3, 4]. In the recent 20 years, with the development of computer and sensor technologies, numerous researches on this subject, agricultural robots, had been reported [11,12,13,14,15]. A wheel mobile robot was designed and developed for the wheat precision seeding. A kinematic model was built for the four-wheel drive robot, and some experiments were taken using this machine. It provided a reference for the design and product of wheat precision seeding robot
