Foot Placement Prediction for Assistive Walking by Fusing Sequential 3D Gaze and Environmental Context

RA-L 2021

Predicting the locomotion intent of humans is important for controlling assistive robots. Previous studies have investigated assistive walking on structured terrains, but only a few studies have considered rough terrains. Human intent on rough terrains is more difficult to predict because there is a

Coverage Sampling Planner for UAV-enabled Environmental Exploration and Field Mapping

IROS 2019poster

Unmanned Aerial Vehicles (UAVs) have been implemented for environmental monitoring by using their capabilities of mobile sensing, autonomous navigation, and remote operation. However, in real-world applications, the limitations of on-board resources (e.g., power supply) of UAVs will constrain the co…

Efficient Autonomous Robotic Exploration With Semantic Road Map in Indoor Environments

RA-L 2019

This letter presents a novel and integrated framework for Next-Best-View (NBV) selection toward autonomous robotic exploration in indoor environments. A topological map, named semantic road map (SRM), is proposed to represent the explored environment during the exploration. The basic concept of the

Exploiting Points and Lines in Regression Forests for RGB-D Camera Relocalization

IROS 2018poster

Camera relocalization plays a vital role in many robotics and computer vision applications, such as self-driving cars and virtual reality. Recent random forests based methods exploit randomly sampled pixel comparison features to predict 3D world locations for 2D image locations to guide the camera p…

Autonomous mobile robot navigation in uneven and unstructured indoor environments

IROS 2017poster

Robots are increasingly operating in indoor environments designed for and shared with people. However, robots working safely and autonomously in uneven and unstructured environments still face great challenges. Many modern indoor environments are designed with wheelchair accessibility in mind. This…

Backtracking regression forests for accurate camera relocalization

IROS 2017poster

Camera relocalization plays a vital role in many robotics and computer vision tasks, such as global localization, recovery from tracking failure, and loop closure detection. Recent random forests based methods directly predict 3D world locations for 2D image locations to guide the camera pose optimi…
