Visual 3D point cloud data is re-projected onto an orthographic RGB-D heightmap, which serves as a representation of the current state s t. The heightmaps are then fed into two FCNs - one Φ p inferring pixel-wise Q values (visualized with heat maps) for pushing to the right of the heightmap and another Φ g for horizontal grasping over the heightmap. The goals of the experiments are three-fold: 1) to. However, in this task, the robot gets positive rewards from environment only when successfully grasping the goal object. or to make general observations of facilities or structures (i.e., security guard, inspection, etc.) The visual hallucinations can be explained as the reference frequencies being miscalibrated. Our method involves using fully convolutional action-value functions (FCAVF) to map from visual observations to two action-value tables in a Q-learning framework. We focus on the task of goal-oriented grasping, in which a robot is supposed to grasp a pre-assigned goal object in clutter and needs some pre-grasp actions such as pushes to enable stable grasps. The space outside of the cone represents all the pushes that would in some way cause an object to slip out of the robot’s grasp.
