However, current methods do not yet scale to high-dimensional inputs in continuous control. Here we present a novel active inference torque controller for industrial arms that maintains the a... |

] | In this paper, we present a capacitance-based sensor array for physical human-robot interaction (pHRI) applications that can measure the proximity, near-zero-force (NZF) contacts, and pressure between a robot and human body. The top segment including the electrodes is made of soft, stretchable materials, while the bott... |

] | The ability to detect that a grasped object is slipping from the robot gripper is a crucial skill for autonomous robotic manipulation. However, current solutions for automatic slip detection do not perform well in real-world unstructured settings, in which a wide variety of gripper-object interactions could occur. Tact... |

] | Recent advances in object segmentation have demonstrated that deep neural networks excel at object segmentation for specific classes in color and depth images. However, their performance is dictated by the number of classes and objects used for training, thereby hindering generalization to never seen objects or zero-sh... |

] | Under-actuated bionic hands have achieved tremendous popularity in many fields because of their advantages of lightweight, budget-friendly, satisfactory flexibility, and adaptability. Except for the bionic mechanical design, various anthropomorphic control strategies have been proposed and investigated in the last deca... |
