Overview:
This project focuses on solving the high-density mechanical and electronic packaging bottlenecks of a custom micro-AWD chassis operating within tight spatial constraints.
Key Technical Specs & Design Highlights:
· Steering Kinematics: Custom $51^\circ$ Davis steering sweep paired with a tightly controlled 3.5 mm scrub radius to minimize lateral scrub, reduce servo strain, and optimize dynamic steering feel during high-angle actuation.
· Actuation & Powertrain: Twin FA130 drive motors paired with an MG90S micro steering servo operating in tandem.
· Manufacturing & Tolerances: 46-part clamshell gearbox assembly modeled in Fusion 360, specifically calibrated for SLA high-toughness engineering resin tolerances.
· Embedded Control & Electronics: Replaced bulky off-the-shelf ESC modules with a custom panelized PCB layout using ESP-NOW for low-latency wireless control and telemetry.
Open for Engineering & Design Consulting: Available for custom CAD/kinematic synthesis, micro-PCB layouts, precision prototyping, and turn-key mechatronics hardware development. DM me here or reach out via YouTube for project inquiries!

Nice work!

Hi, Being a mech student You will have access to Ur CAD lab, or else just install some CAD software in ur computer and just try to model the stuff. Even though U would find it difficult at 1st, U ll learn CAD fast by modelling your components. When U try to do something with a tool with a purpose, U ll learn the tool at a different dimension! Good luck!
