Agricultural robots are an important part of modern agricultural production tools.As a production tool for modern agriculture,agricultural robots can greatly increase the efficiency of agricultural production and ensure the output of crops.In order to shorten the cycle time and high cost of the traditional agricultural robot development model,this paper will use computer-based virtual reality(VR)technology incorporating multi-disciplinary achievements to apply to the simulation of the operation behavior of litchi picking robots to reduce time and cost.cost.This paper proposes the use of virtual reality technology to construct the operating scene of fruit and vegetable picking robots.This paper analyzes the kinematics of picking robots,and this paper studies the positioning process of the picking robot vision system to improve the target positioning accuracy of picking robots.With real-time,interactive features.Aiming at the virtual experiment requirements of litchi picking robots,starting from the aspects of modeling technology,modeling methods,and physical model data structure,combined with the application of Unity3 d standard resource library,terrain editor,lighting,sky box,etc.,a litchi picking robot operation was created.The performance simulation system's finesse and geometrical motives provide a realistic three-dimensional litchi picking environment for subsequent research.According to the performance characteristics of the litchi picking robot,the kinematics dynamics analysis of the robot and the target positioning process of the picking robot are analyzed.The robot arm and end effector,binocular vision camera of the Litchi picking robot are created using 3ds Max,and Kinect device model.It provides a theoretical basis for performance testing of litchi picking robots.Unity3d platform is used to integrate the model,and the 3D environment system is optimized in the system.Combining the physics engine and the geometric model of the litchi picking robot,a simulation system of the operation behavior of the litchi picking robot following the objective physical laws is created,and the virtual experiment scenario is displayed.Performance tests and experimental results of litchi picking robots,and evaluation of virtual test performance based on simulation data.The system implements human-computer interaction through monitoring functions and event-driven methods,controls the movement state of the virtual Litchi picking robot through the keyboard input,and realizes the realistic trajectory of the end-effector of the Litchi picking robot in the scene,which is the theory of picking robots for agricultural litchis.Research and system design provide innovative methods and technical support.
