    • Master's Project: Adaptive Surgical Robotics
      • Oct 2020 - Jun 2021

      Master's Group Project: Design and build an adaptive robot capable of skin lesion removal surgery. This required an interdisciplinary collaboration to resolve the requirements of significant subsystems: vision system, mechanical design, electronics, end effector design, and adaptive programming. • Finalized the surgical robot system by analyzing the functional requirements gathered from consultations with the stakeholders and using FMEA to evaluate each subsystem• Conceptualized the mechanical design for the cartesian robot by investigating the technical requirements for CNC machines and using morphological analysis to determine which components to incorporate• Built the cartesian robot on time by managing the procurement process, creating a detailed CAD design in SolidWorks, conducting structural analysis, and implementing GD&T to define the parts for CNC milling• Hand-calculated the torque requirements for each linear actuator to select motors for the 3-axis movement• Optimized workflow during strict COVID restrictions using project management tools (Gantt chart and risk registers) to determine critically linked tasks and mitigate issues Show less

    • Wind Turbine Blade FEA
      • Nov 2020 - Nov 2020

      • Observed the deformation and stress on a wind turbine blade when deactivated due to high wind speed by conducting a Finite Element Analysis (Ansys) on the blade’s shell model• Verified FEA results using hand-calculated structural analysis; the deformations and stresses were of the same order of magnitude, but discrepancies occurred due to simplified assumptions in the calculations.• Demonstrated reliability by conducting a mesh convergence study and a mesh quality analysis

    • Third Year Dissertation: Enzymatic Mineralization of WPI Hydrogels Using ALP
      • Oct 2019 - Mar 2020

      The fabrication of the whey protein isolate (WPI) hydrogels requires thermal gelation which denatures the mineralization facilitating enzymes (Alkaline Phosphatase aka ALP), therefore, alternative methods of incorporating ALP after hydrogel fabrication was investigated.Created three alternative methods of incorporating ALP into WPI hydrogels1) ALP diffusion to non-lyophilized hydrogels2) ALP diffusion to lyophilized hydrogels3) Incorporating thermal resistant Halloysite-ALP into the WPI mixture• The mineralized composite containing WPI and phloroglucinol (PG) had a young's modulus 2.5 times higher than the non-mineralized control (40%w/v WPI) suggesting that PG and mineralization improved their mechanical strength.• Identified that incorporating PG showcased potential in controlling the rate of biomaterial degradation Show less
