From concept to prototype.
From test to root cause.

Bachelor’s in Electronic Information Science and Technology, with hands-on experience in medical-electronics R&D testing and cross-disciplinary prototype development. On most projects I own the core technical work end to end: hardware, mechanical structure, software, vision and system integration. I measure first, then conclude.

Measure first,
then conclude.

The first thing I did on a medical-electronics R&D team was build the test bench and bring the waveforms back. I work the same way on prototypes: when something goes wrong, I hook up the instruments, narrow it down with data, and only then change things.

Zhiyong Youth STEM Innovation 智勇青少年科创

STEM Project Mentor (Prototype Development)
  • Turned project ideas and requirements into engineering plans; on most projects, independently handled component selection, hardware and mechanical build, software and vision development, system integration and delivery.
  • Made trade-offs within budget, fabrication and schedule limits; resolved communication, control and recognition issues by reproducing faults, comparing conditions and tuning parameters and structures.
  • Worked directly with stakeholders on functional goals, technical feasibility and scope; ran testing, demos and iterations. Representative projects: vision-guided sorting arm, human-following tracked robot.

Vision positioning & grasp control

Turns the 2D image from a USB camera into arm motion: recognizing, locating, picking and binning red, yellow, green and blue blocks.

Recognition
HSV color segmentation, contour analysis, multi-frame stability check
Mapping
16-point workspace calibration with piecewise affine mapping
Execution
Inverse-kinematics pre-check, joint-range validation, angle read-back and single-joint resend
