I am Chi-Ju, a huge fan of autonomous robots from Taiwan. Love to take on any challenge and explore more about our new tech world!

Work Experience

Software Engineer at Zoox [Jun 2020 - Present]

Software Engineer at Orbbec 3D Technology [Jun 2019 - Aug 2019]

• Designed and implemented an extrinsic calibration algorithm for little-overlapping dual-camera systems
• Developed and maintained Orbbec ROS package

Firmware Engineer at Actions Microelectronics [Dec 2017 - March 2018]

• Devoloped wifi display functions of EZCast.

Software Engineer at DMP Electronics [Oct 2014 - Aug 2014]

• 86Duino Motion Editor: Developed a frame-based motion editor for multi-functional robots.
  • Supported various input devices, such as the keyboard, WiFi, Ethernet, Bluetooth, and PS2 joystick, for controlling robots.
  • Integrated inertial measurement units (IMU) that can help robots resist shocks and vibrations
  • Implemented approaches to generate cubic splines for smoothing the trajectory of servo motors
  • Designed and implemented the two-layer motion blending feature for creating more flexible motions
  • Implemented templates to automatically generate firmware that replaces manual coding work
  • Integrated firmware with Scratch 2.0 that users can program their robots with graphical blocks
  • Applied to two 3D-printable robots, including a hexapod, 86Hexapod, and a biped robot
• 86Duino SDK
  • Linux SDK: allow users to manipulate 86Duino I/Os in Linux environment
  • libMRAA Porting: allow users to manipulate I/Os with C/C++, Java, Python or JavaScript
  • AIServo86: a library of controlling smart actuators such as Dynamixel servos
• Robots
  • Designed and implemented firmware of 3D-printable robots including a hexapod and a humanoid robot
  • Built internal packages to integrate ROS with the 86Duino ecosystem

Education

University of Colorado Boulder

• Master in Computer Science, GPA 4.00/4.00 [2018 - 2020]
  • Human Interruption Detection in HRC
    • Developed an approach to allow robots to detect users’ intention to interrupt a robot mid-execution based on visual and audio signals. The goal is to improve interactivity in Human-Robot Collaboration tasks.
      • Implemented Dynamic Safety Margin controller on Sawyer based on MoveIt! and KDL
      • Developed a system to detect the beginning of interruptions using OpenFace
  • 1/10-scale Mini Race Car
    • Designed and developed an autonomous system integrating Rock64, RealSense D435i, and Pololu controller.
      • Implemented a remote control and debugging package to speed up development
      • Implemented a state machine using depth data to achieve the fastest record in class to complete a route
      • Integrated ORB Slam with RealSense to create sparse map while moving
  • HIRO-group Research Assistant
    • Developed infrastructures including motion control interfaces, sensor integration, and simulation

National Chiao Tung University

• Master in Computer Science, GPA 4.00/4.00 [2013 - 2014]
  • Publication
    • Chi-Ju Wu, and Wen-Hsiang Tsai, “Construction and Applications of Message-rich Videos for Pervasive Communication,” Proceedings of 2014 Conference on Computer Vision, Graphics and Image Processing, Pintung, Taiwan, Aug. 2014.
      • Proposed and implemented an approach to embed and extract hidden messages in videos. It can extract messages via capturing videos directly from monitors with 98.8% correctness
• Bachelor in Computer Science, GPA 3.75/4.00 [2009 - 2013]
  • Activities
    • Cheerleader: First Prize in University Cheerleading Championship (Division 2), Taiwan, 2011.
    • Go: The fourth in National University Go Competition (Division 2d), Taiwan, 2010.
