Antweight Battlebot (454 grams) with a machined titanium spinner.
Currently in the process of creating my High School's battlebot team with my friends! We are in the process of getting the titanium spinner machined and shipped to us, and ordering materials to lay our own carbon fiber.
The "Clamshell" walls will be printed with my teacher's Bambu H2S with carbon fiber nylon filament. A roll of 500g is ~$30 and is very durable.
Total cost was around $220+ on amazon, but we ordered the same stuff off AliExpress for ~$95. Pretty awesome if you ask me.
Electronics and such are listed in google sheets. (I'm not sure if I can post links here??)
Some notable parts we ordered
1. Emax RS2205 (Weapon Motor)
2. 30A ESC BLHeli (Weapon ESC)
3. FrSky RX4R (Receiver)
We hope to finish and compete with this robot during September.
Thanks for reading!
