Verification Testing for Surgical Robot
TEAMMATES
Electro-Mechanical (EM) Team Manager
EM Senior Engineer (Design Verification Test lead)
ROLE
Took ownership of robot-to-catheter force testing under the supervision of senior engineers as part of the Electro-Mechanical (EM) team.
CHALLENGE:
Ensuring Robot Compliance with Catheter Force and Wire Torque Requirements
The neuroendovascular robotic platform needed to meet stringent force and torque requirements for safe and precise navigation through delicate vascular pathways. Verifying these parameters required custom testing setups and accurate data analysis.
SOLUTION:
Ensured robot precision and safety through rigorous testing and data-driven analysis.
Conducted over 40 tests to verify robot force and torque performance.
Built and optimized electromechanical test fixtures, troubleshooting transducer setups to ensure accurate readings.
Created 10 Design Controls documents to ensure compliance and traceability.
Developed MATLAB algorithms to automate data processing from Simulink, generating clear test reports and conducting statistical t-tests to flag potential failures.
Conducted 40+ Design Verification tests
