OHO: A Multi-Modal, Multi-Purpose Dataset for Human-Robot Object Hand-Over

open access: yesSensors, 2023
In the context of collaborative robotics, handing over hand-held objects to a robot is a safety-critical task. Therefore, a robust distinction between human hands and presented objects in image data is essential to avoid contact with robotic grippers. To
