About

I am a second-year Master's student in the Robotics Institute at the University of Michigan, USA. Prior to that, I was a Research Assitant at National Taiwan University where I earched my Mechanical Engineering Bachelor degree. My research interest is perception in robotics, medical, and health care aspect. I am looking for PhD positions in robotics. If you are interested in hiring, please contact me!

Projects

Image Caption Generator with Simple Semantic Segmentation

Utilized a pre-trained ImageNet as the encoder, and a Long-Short Term Memory (LSTM) net with attention module as the decoder in PyTorch that can automatically generate properly formed English sentences of the inputted images and achieved BLEU-4 score 0.2320 (out of 1) with beam search size 5 in evaluation. Implemented a simple semantic segmentation algorithm using the sentence generated along with it’s attention layer.

Evaluation of LeGO-LOAM

Evaluated LeGO-LOAM (Lightweight andGround-Optimized Lidar Odometry and Mapping) which reduced computational expense while keeping similar accuracy compared to LOAM method using KITTI Odometry Benchmark Dataset, UTBM Dataset and KAIST Urban Dataset. Compared the mapping and odometry results of these data, and analysis the relative motion and mapping error in this report.

Vehicle Classification and Localization

Utilizing OpenCV for image preprocessing and TensorFlow for DenseNet deep learning to classify 22 different types of vehicle and localize them by point cloud data.

Mobile Robot with Particle Filter and Path Planning

Implementing a waypoint navigation system, a simultaneous localization and mapping (SLAM) system using 2D LiDAR, an A* path planning algorithm, and a visualization of the environment for a mobile robot.

Teaching

I am actively seeking GSI position at University of Michigan to support my graduate study.

EECS 565: Linear Feedback Control Systems -- Winter 2019, Grader

This courses builds on undergraduate frequency domain methods and graduate-level state-variable methods in order to develop feedback design concepts for linear multivariable systems.

Outreach

UM Discover Engineering

Helped design and organize a robotics coding activity for a two day camp for local high school students. Guided students in the workshop through the robotics line following and grasping task. The camp focused on increasing their interest in STEM, as well as over-viewing its academic and career paths.

Ann Arbor Summer Festival KidZone

Explained the theory and the usage of Lidar to local families.
