So you make a thing - spend $20 in parts ... play with it for a day or three ... then you need another $20 ...

(sigh)

After a few dozen 'bots, the thought surely occurs: Wouldn't it be nice if we could just standardize & re-use the expensive parts?

With that thought in mind, the mission is of THIS 'kata is to create a 'bot independent drive chassis for "Bradley-bolting" onto whatever we NEXT need melt together. 👌

🌟NEW:: Yes, like us I know that you've possibly a lot of 'bots to keep tack of ... so we've added a labeled control box.

👉The lid herein features the Python logo and a "BULLET:BOX" name, but
👉The box is here.

🌟NEW: Use the *Pct200.stl for the largest BulletBot print (160mm!)
🌟NEW: Baseplate with built-in supports for those MG90 / SG9 Servos!
🌟NEW: Baseplate with support for the popular 'begeared N20 DC Motors!

Note that:

✅ The Mark VI is half the thickness - and therefore faster to print than the Mark III.

✅ Designed to be infinitely scaled; print as-is for a 1mm rendition.

✅ Added a horn design to employ as a tire 'gear' (🎓if using a servo, then use your servo's circular horn. 🎖️)

✅ Strap-in two common MG90S Servos, N20's, or their nearest dimensional equivalents ...

✅ AND use the new grid-plate!

Happy 'Hackin!

p.s. If my inspirations are saving you cash, then please feel free to 'ko-fi me a 'cuppa @ https://ko-fi.com/randallnagy ... and we'll share more. 😉

and if you TRULY want to go green - change the world - do more with less - then simply get any major AUTOMOBILE 'manufacturer to Bradley-kit together something for THEIR showrooms ... that's pretty much how all factories work anyhoo? 😲
