 # binPicking
 Central repository for our large-scale and efficient bin-picking project. wiki will be a central repository for all aspects of this work.
+
+## Visual Feedback
+For visual feedback, this project will utilize a Graph-based neural network deep reinforcement learning for object detection and tracking.
