autonomous-racing-systems
A traceable simulation and mechanical-design study whose mast baseline failed its own modal guard before a redesigned, converged FEA passed.
projects
Engineering case studies with the evidence level stated up front: field hardware, tested prototype, converged simulation, or software benchmark. Photos on cards for simulation and software projects are illustrative and credited on each page.
hardware & prototypes
V-Aid Climbing Tactile Pin Array
A 12 x 12 tactile pin array that converts a climbing-route image into a raised pattern a blind climber can read by hand.
multirotor-recovery-dynamics
A simulation-to-bench program in which placeholder torque fails, assumed mixer authority passes, and a frozen measurement gate decides whether fabrication continues.
sensor-enclosure-thermal-design
A field-deployed enclosure for an urban air-quality node, iterated through four printed revisions around airflow, rain path, packaging, and power.
RoboMaster Launcher Packaging and Flywheel Prototype
Launcher packaging for a RoboMaster gimbal: a printed flywheel, supercapacitor shell, and armor fitted around a 20.5 mm feed path.
research & simulation
soft-actuator-recalibration
A 2,000-trace, actuator-split simulation study that tests P-V loop area as a recalibration signal and preserves the negative lead-time result.
informal-road-mapping
A preregistered remote-sensing method that finds persistent surface-disturbance corridors for high-resolution review rather than claiming to classify sub-pixel roads directly.
software & tooling
MechAudit
A domain-bounded verifier that independently recomputes mechanics and compares detected failure modes against annotated LLM calculation captures.
Nomad
A research-mapping web app with multi-query retrieval, deterministic ranking, and an 88-test suite; a keyed relevance evaluation remains the open measurement.
