Image-to-Action Translations Based Object Grasping Strategy without Depth Information and Robot Kinematics Analysis.

The main objective of this paper is to utilize only RGB images to let a robotic arm grasp a target object without the related 3D position information. The advantages of the proposed method include image-to-action translations that apply to a class of general robotic arms, and the mathematical analysis of the inverse kinematics is not necessary. We employ the RGB images and the proximal policy optimization (PPO) algorithm to train the reinforcement learning network in the Gazebo simulated environment. Finally, an illustrative example shows how effective the proposed strategy is.
