This was my first Beetleweight combat robot build, it's name is Turtle.
Turtle was built for the "9 Hour Beetleweight Challenge"
facebook.com/groups/UnofficialRobotWars/permalink/591995247746911
The objective of the challenge is to show that anyone can have a go at building a combat robot and not require any elaborate equipment or building processes (CAD or CNC). Also you gotta have fun!
Before attempting yourself and/or requesting build guides for a beetleweight, I'd suggest building an Antweight (150 grams) combat robot first. They are far easier and cheaper to build and will give you a great working knowledge of combat robot building and electronics.
Rules:
1) The robot must be battle ready in 9 hours start to finish
2) Spinners of any kind are banned this is for both safety and so it can be a simple arena for people to make themselves
3) Basic powertools only (jigsaw,powerdrill,pillar drill etc) no mills or lathes of any kind are allowed
4) All forms of cnc or cad are banned you want precision get a ruler
5) The bot must conform to FRA rules and regulations
6) Robots should be built to 1.36kg but if you do need to go up to 1.5kg (the uk limit) that's acceptable
7) You are not allowed to premeasure, make or design any part of your bot before the 9 hour clock starts and during that time no parts may be purchased
My build was finished in 6.5 hours and weighed in at 1.24kg at the end. He's a parts list:
- Battery 850mAh hobbyking.com/en_us/turnigy-nano-tech-850mah-3s-45-90c-lipo-pack.html
- 4 Gearmotors botbitz.com/product/bot-bitz-1000rpm-gearmotor
- 2 30A Botbitz ESC's botbitz.com/product/botbitz-30ampv2-electronic-speed-controller
- V-Tail Mixer hobbyking.com/en_us/turnigy-v-tail-mixer-ultra-small.html
- 2nd hand hobby touring car wheels
- 4mm D shaft to 12mm hex adapters https://littlebirdelectronics.com.au/products/12mm-hex-wheel-adapter-for-4mm-shaft-2-pack
