It reduces interference from redundant information and improves grasping accuracy. SA-Grasp achieved high detection accuracies of 98.37% on Cornell and 96.33% on Jacquard datasets, with a fast detection time of 21 ms per image. In real-world tests, it demonstrated a 94.44% success rate across 180 grasping attempts on 9 unknown objects, demonstrating its reliability. SA-Grasp is a lightweight visual grasping pose detection network characterized by high grasping success rates and fast speeds, providing a new approach for the application of self-attention mechanism in the field of robotic arm visual grasping.
