High-Precision Mechanical
Design & FEA Engineering

A four-layer systems optimisation framework for a robotic arm powered entirely by Microbial Fuel Cells — covering mechanical feasibility, energy modelling, supercapacitor storage, and MFC stack design. Identified the EMAX ES08A II as optimal, achieving 2,461 theoretical actuations from 10g of apple flesh.

COMSOL multiphysics modelling of a CPU heat sink — with and without a spreader plate — to assess and optimise heat dissipation performance. Fin geometry was systematically varied across thickness, radius, depth, and length parameters. A companion radial fin array study optimised external pipe cooling geometry through both stationary and transient thermal analysis.

Full structural simulation of a marine racing keel using ANSYS, covering von Mises stress distribution, maximum bending conditions, and multi-directional impact loading. Conducted to assess structural performance, validate user safety margins, and demonstrate regulatory compliance under competitive racing conditions.

A fully autonomous prototype rover designed to locate, collect, and deposit simulated specimens across a defined zone. Combines proximity sensing, Arduino control, and precision navigation to achieve positional accuracy under 5mm. The chassis was laser-cut from plywood for structural precision, with 3D-printed internals for ball channelling, hinge mechanisms, and sensor mounts.

Concept design and CAD development of a pressure-rated underwater CTD sensor for marine location surveying at depths up to 300m (30 bar). Engineered for low-maintenance deployment intervals, incorporating integrated data transfer systems and an optimized, cost-conscious approach to serviceability and manufacture.
