## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-929:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/POLOLU-929:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

**How it works**

Motor rotation is transferred to the legs via crank plates and linkage rods, causing the Mechanical Beetle to walk forwards or backwards at one of two selectable speeds. A linkage rod connected to the beetle’s front right leg swings its horn left and right as the beetle walks. When it bumps into an obstacle, the beetle automatically turns to avoid it and continues walking. Because of this behavior, the beetle can provide amusement by simply running around in a small, enclosed space. The body is made from a transparent green ABS resin that allows you to see all of the motors, gears, cranks, and linkage rods in action.
