“…Secondly, mechanization in agriculture requires a high quality and skill people to run and to apply technology and engineering [18][19][20][21][22]. It is mentioned that increase investments in science and technology for mechanization and agricultural processing industry development should be one of the priorities in agricultural production.…”

Agricultural mechanization is an essential path to the industrialization of rural regions. Viet Nam has more than 40% of the population in the agriculture sector, contributing nearly 30% of the country's GDP and still is an agricultural country. Mekong River Delta (MRD) is the most significant agriculture production region of Viet Nam in which Vinh Long is one of sample province might be representative for MRD. This paper presents case study of recent status of mechanization in agriculture, and some recommendations for development the agricultural mechanization in the province. The statistical methods, SWOT analysis, problem approach and practical research have been used. The results indicate that the ratio of agricultural mechanization in Vinh Long might be not to satisfaction to the development of agriculture production. The agricultural field using walking tractors and shoulder engines, investment and financial policies, skill and training level of farmers and agricultural infrastructure such as rural transportation system, irrigation system, and agricultural production industrial processing are the main factors strongly influence on the development of agricultural mechanization in Vinh Long. Some studies proposed recommendations as solutions for sustainable development of the agricultural mechanization are presented in this study, such as agricultural production needs to be reorganized; developing system for training high quality and skill people to work in mechanization process; increase investments in science and technology for agricultural mechanization; setting up the policies to attract businesses and individuals invest in developing mechanization; removing blockages on "agricultural land limit" policy; and creating financial policies supporting to agricultural production investors.

“…However, with the continuous development of bionics, materials science, sensor technology, intelligent control and image acquisition technology, we should believe that the biomimetic robot fish which can be accurately controlled and is high efficiency, high-velocity, energy saving, low noisy and stable must be manufactured in the future. And this kind of robot fish will play an important role in the future UUVs, and further step into people's daily life [47][48][49][50][51][52][53][54].…”

The obstacle avoidance controller is a key autonomous component which involves the control of tractor system dynamics, such as the yaw lateral dynamics, the longitudinal dynamics, and nonlinear constraints including the speed and steering angles limits during the path-tracking process. To achieve the obstacle avoidance ability of control accuracy, an independent path re-planning controller is proposed based on ROS (Robot Operating System) nonlinear model prediction in this paper. In the design process, the obstacle avoidance function and an objective function are introduced. Based on these functions, the obstacle avoidance maneuvering performance is transformed into a nonlinear quadratic optimization problem with vehicle dynamic constraints. Moreover, the tractor dynamics maneuvering performance can be effectively adjusted through the proposed objective function. To validate the proposed algorithm, a ROS based tractor dynamics model and the SLAM (Simultaneous Localization and Mapping) are established for numerical simulations under different speed. The maximum obstacle avoidance deviation in the simulation is 0.242 m at 10 m/s, and 0.416 m at 30 m/s. The front-wheel rotation angle and lateral velocity are within the constraint range during the whole tracking process. The numerical results show that the designed controller can achieve the tractor obstacle avoidance ability with good accuracy under different conditions.
