Kinematic Motion Retargeting via Neural Latent Optimization for Learning Sign Language

RA-L 2022

Motion retargeting from a human demonstration to a robot is an effective way to reduce the professional requirements and workload of robot programming, but faces the challenges resulting from the differences between humans and robots. Traditional optimization-based methods are time-consuming and rel

Learning Interpretable BEV Based VIO without Deep Neural Networks

CoRL 2022poster

Monocular visual-inertial odometry (VIO) is a critical problem in robotics and autonomous driving. Traditional methods solve this problem based on filtering or optimization. While being fully interpretable, they rely on manual interference and empirical parameter tuning. On the other hand, learning-…

One RING to Rule Them All: Radon Sinogram for Place Recognition, Orientation and Translation Estimation

IROS 2022poster

LiDAR-based global localization is a fundamental problem for mobile robots. It consists of two stages, place recognition and pose estimation, which yields the current orientation and translation, using only the current scan as query and a database of map scans. Inspired by the definition of a recogn…

Assembly Sequence Generation for New Objects via Experience Learned from Similar Object

IROS 2021poster

Assembly orders of components have direct influence on feasibility and efficiency of assembly process in manufacturing and are usually defined by experienced operators. To automate the assembly sequence generation process, we present a method using the idea of case-based reasoning, which can take ad…

Imitation Learning of Hierarchical Driving Model: From Continuous Intention to Continuous Trajectory

RA-L 2021

One of the challenges to reduce the gap between the machine and the human level driving is how to endow the system with the learning capacity to deal with the coupled complexity of environments, intentions, and dynamics. In this letter, we propose a hierarchical driving model with explicit models of

Learn to Differ: Sim2Real Small Defection Segmentation Network

IROS 2021poster

Recent studies on deep-learning-based small defection segmentation approaches are trained in specific settings and tend to be limited by fixed context. Throughout the training, the network inevitably learns the representation of the background of the training data before figuring out the defection.…

Neural Motion Prediction for In-flight Uneven Object Catching

IROS 2021poster

In-flight objects capture is extremely challenging. The robot is required to complete trajectory prediction, interception position calculation and motion planning within tens of milliseconds. As in-flight uneven objects are affected by various kinds of forces, which leads to the time-varying acceler…

PREGAN: Pose Randomization and Estimation for Weakly Paired Image Style Translation

RA-L 2021

Utilizing the trained model under different conditions without data annotation is attractive for robot applications. Towards this goal, one class of methods is to translate the image style from another environment to the one on which models are trained. In this letter, we propose a weakly-paired set

Deep Phase Correlation for End-to-End Heterogeneous Sensor Measurements Matching

CoRL 2020

The crucial step for localization is to match the current observation to the map. When the two sensor modalities are significantly different, matching becomes challenging. In this paper, we present an end-to-end deep phase correlation network (DPCN) to match heterogeneous sensor measurements. In DPC
