N2 - Training robots in real-world environments can be challenging due to time and cost constraints. To overcome these limitations, robots can be trained in virtual environments using Reinforcement Learning (RL). However, this approach faces a significant challenge in obtaining suitable data. This paper proposes a novel method for training collaborative robots in virtual environments using synthetic data and the point cloud framework. The proposed method is divided into four stages: data generation, 3D object classification, robot training, and integration. The first stage of the proposed method is data generation, where synthetic data is generated to resemble real-world scenarios. This data is then used to train robots in virtual environments. The second stage is 3D object classification, where the generated data is used to classify objects in 3D space. In the third stage, robots are trained using RL algorithms, which are based on the generated data and the 3D object classifications. Finally, the effectiveness of the proposed method is integrated in the fourth stage. This proposed method has the potential to be a significant contribution to the field of robotics and 3D computer vision. By using synthetic data and the point cloud framework, the proposed method offers an efficient and cost-effective solution for training robots in virtual environments. The ability to reduce the time and cost required for training robots in real-world environments is a major advantage of this proposed method, and has the potential to revolutionize the field of robotics and 3D computer vision.
