Predicting Stable Configurations for Semantic Placement of Novel Objects

Chris Paxton, Chris Xie, Tucker Hermans +1

Human environments contain numerous objects configured in a variety of arrangements. Our goal is to enable robots to repose previously unseen objects according to learned semantic…

FiG-NeRF: Figure-Ground Neural Radiance Fields for 3D Object Category Modelling

Christopher Xie, Keunhong Park, Ricardo Martin-Brualla +1

We investigate the use of Neural Radiance Fields (NeRF) to learn high quality 3D object category models from collections of input images. In contrast to previous work, we are able…

Amodal 3D Reconstruction for Robotic Manipulation via Stability and Connectivity

William Agnew, Christopher Xie, Aaron Walsman +4

Learning-based 3D object reconstruction enables single- or few-shot estimation of 3D object models. For robotics, this holds the potential to allow model-based methods to rapidly a…

Unseen Object Instance Segmentation for Robotic Environments

Christopher Xie, Yu Xiang, Arsalan Mousavian +1

In order to function in unstructured environments, robots need the ability to recognize unseen objects. We take a step in this direction by tackling the problem of segmenting unsee…
