As part of Cheforge, I worked on the mechanical development of our autonomous cooking robot, a system designed to help individuals who lack the time or physical ability to prepare meals themselves. The robot heats, stirs, seasons, and cooks ingredients inside a compact countertop unit, enabling fully hands-off meal preparation with consistent results.
My role centered on mechanical R&D, with a focus on optimizing the robot’s core mechanisms. This included upgrading the stirring system to achieve broader surface coverage and more repeatable motion, designing a precise spice-dispensing mechanism for consistent seasoning, and increasing the load capacity and reliability of the rotating ingredient tray.
Created the exterior surface geometry using curvature-continuous lofts and smooth transitions to achieve a polished, consumer-grade appearance while keeping all features compatible with injection-molding DFM requirements.
Developed the overall product design, including proportions, panel breaks, interfaces, and visual hierarchy, to communicate reliability and simplicity while integrating functional access points and sensor and actuator clearances.
Designed a modular sheet-metal chassis that allowed mechanisms to be swapped and tested quickly, with standardized mounting points and simplified geometry to support fast iteration during R&D.
Optimized the chassis for DFM/DFA by minimizing part count, using bend-friendly features, and aligning tolerances so panels could be manufactured, assembled, and serviced easily with consistent repeatability.
Developed a dual-linkage stirring mechanism achieving proportional motion from a single actuator through dual belt-pulley stages coupled to planetary gearing, allowing the robot to cover a larger cooking surface with smoother, more controlled motion while keeping the design mechanically simple and manufacturable.
Repositioned the stirring motor rearward in the assembly to decrease cantilever loading on the output shaft, improving overall structural stiffness and making the stirring system more reliable under heavy or high-viscosity food loads.
Designed a compact Archimedes-screw ingredient dispenser driven by a high-resolution servo for precise, repeatable dosing, with geometry optimized to prevent bridging and jamming.
Engineered a moisture-resistant enclosure with smooth internal surfaces and sealed interfaces to keep ingredients dry and free-flowing in the robot’s high-humidity cooking environment.
Upgraded the ingredient tray drive from a belt-pulley system to a compact planetary gearbox, increasing torque capacity and positional accuracy while reducing overall volume.
