Ruihang Chu, Yuru Zhang, Hongdong Zhang, Dangxiao Wang*, Weiliang Xu, Jee-Hwan Ryu.
Accepted by IEEE Transactions on Haptics(JIF=2.757). Annual Best Paper Candidate.

- It is difficult to stimulate hard contact and small inertia simultaneously in virtual environment for haptic device.
- Introduce a co-actuation module to overcome this difficulty.
- Demonstrate the effectiveness of co-actuation on a 2-DOF haptic device.
- The device can render a virtual wall with the stiffness as high as 65N/mm. The effective inertia is 35-145g.

Human Flow Tracking System (Team Leader) [Demo]

We develop a real-time software system for human flow tracking. It can be applied in new retail industry. The technologies involve pedestrian detection, re-identification and multiple object tracking.

IJCAI-19 Alibaba Adversarial AI Challenge

We implement PNASNet-5 as backbone and adopt CosFace to improve recognition performance. We train our defense model at the presence of adversarial samples generated by fast gradient sign method. Moreover, we re-detect the objects with a tighter bbox to overcome the disturbance from the background. We rank 36th among 2520 teams in the finals (1.4%).

An Intelligent Robot Based on Ros and Android System (Team Leader) [Code] [Demo]

We propose to replace the expensive sensors by one android phone when making intelligent robot. Equipped with our provided robot chassis and software system, any Android owner has access to develop his/her personal robot. We believe it makes developing robots more approachable for robot fans. Specifically, we obtain the measured data from phone sensors, processing the data with ROS and delivering it to STM32, which serves as the controller. Finally, our robot integrates functions such as object tracking, speech recognition and grabbing. This project won the first prize in China Intelligent Product Design Competition in 2015.

Control the 3-DOF worktable through a Kinect (Team Leader) [Code] [Demo]

We develop a mechatronic system based on Kinect and 3-DOF worktable. The system obtains the real-time position of human key points from Kinect, and then records the trajectory of human hands.The trajectory can be converted to the G code file (the command in numerically controlled machine) through CAM software. To make it understandable, our plug-in component interprets the G code and guides the 3-DOF worktable to draw the same trajectory.

China University Robot Competition

We develop two automatic robots which work cooperatively to overrun obstacles and climb the final pillar. We won the 3rd prize in national finals.

A New Wall-climbing Robot

When I was a visiting student in Seoul National University, HKUST and THU, we propose a new mechanism that enable robots to walk on the ground and climb the wall. We combine the wheel and paddle in one component. The novel scheme works theoretically yet needs further experimental verification. This project was reported by "I have heirlooms", the CCTV show, in Jul 16, 2017.
