Lunn Dynamics // Robotics & Mechatronics
I design multi-domain robotic platforms for ground, air, surface and subsea, and publish the engineering tools I build along the way. Free, live, and priced for Australia.

Prices and stock refreshed hourly
Priced in AUD, refreshed hourly, Australian vendors first.
Groundschool // New to this?
Six plain explanations of how the parts actually get chosen: sizing an aircraft, reading a motor datasheet, why watt-hours beat milliamp-hours, what an ESC amp rating means, servo torque and splines, and what autonomy needs.
Tool Live
5,330 commercially available parts across seven categories, normalised to AUD with Australian lead times, derived performance metrics, and a compatibility graph linking accessories to what they fit.

Project In development
A local-first voice assistant for the workshop. Wake word, GPU Whisper transcription, neural speech, and a pluggable tool system, with the whole loop running on one desktop.

Project In development
Five robotic platforms across four domains on one shared software stack, building towards Chimera, a vehicle that both flies and swims.

01
Most component databases quote USD, and lead times from somewhere else. That tells an Australian engineer nothing useful.
Everything here is stored in AUD, Australian vendors are checked first, and prices are refreshed hourly. Eleven other currencies are one click away.
02
Every figure traces back to the page it came from, and estimates are labelled as estimates.
Derived metrics name the inputs behind them. Compatibility links state the evidence that produced them rather than simply asserting that two parts fit.
03
Specifications are rarely where a scraper expects them.
This one reads manufacturer PDFs and spreadsheets, infers the column layout of thrust tables rather than assuming it, and runs OCR over the parameter sheets this industry publishes as JPEGs.
