Hello, I'm
Joshua Liu
Robotics research engineer with 10+ years of experience building medical and automation systems across teleoperation, sensing, and real-time control. I specialize in ROS2, robot integration, and turning complex prototypes into reliable systems.
/ Career
A brief overview of my career
Robotics Research Engineer
Institute of Integrative & Innovative Research, University of Arkansas
Led development of real-time autonomous and teleoperation systems, including integrating F/T sensing, 3D camera, AR/VR, and haptics device. Built ROS2 software framework, encompassing real-time sensing, navigation, planning, and control for high-precision applications.
Research Engineer
Laboratory for Computational Sensing and Robotics, Johns Hopkins University
Implemented sensor fusion, improved system architecture, and migrated legacy code to the ROS2 framework, improving modularity and maintainability of multiple robotic systems.
Research Engineer
Hopkins Extreme Materials Institute, Johns Hopkins University
Automated and simulated the workflow for materials testing using Siemens PLC-controlled conveyor systems with multiple UR robots. Deployed the automation of the laser shock subsystem and supported the X-ray subsystem integration.
Postdoctoral Research Fellow
Laboratory of Biomechanical and Image Guided Surgical Systems, Johns Hopkins University
Developed robotic systems for spinal/hip surgery and designed capacitive shape sensors for dexterous continuum manipulators. Supported the medical imaging workflow for both image-guided orthopedic surgery and the development of a total-body photography system for skin lesion detection.
Ph.D. in Mechanical Engineering
Johns Hopkins University
Dissertation: Robotic Implant Modification for Neuroplastic Surgery Advisor: Dr. Mehran Armand Designed and implemented robotic systems for neuroplastic surgery implant modification, including a 5-axis laser cutting system with full-stack development (mechanical design, ROS2 control, registration, toolpath optimization). Built a miniature optical tracking & projection mapping system using RGB-D camera. Developed an automated pipeline using designed reattachable fiducial markers for intraoperative patient-CT registration and implant modification.
Robotics Summer Intern
BMW Group
Contributed to ROS framework development for a self-driving car research platform and created an RViz visualization plugin for laser radar sensors.
M.S.E. in Mechanical Engineering
Johns Hopkins University
Graduate studies focused on robotics and mechanical system design.
B.S. in Mechanical Engineering
Changsha University of Science and Technology
Undergraduate foundation in mechatronic system design and manufacturing.
