Building a Winning Combat Robot - Split

Split is my attempt at a more meta style machine known as a '4WD Vertical Spinner'. This type has theoretical advantages in damage output and control, but theres more to building a robot than the concept. The robot is built from a mix of steels, carbon fiber and plastics designed to maximise durability and deliver a destructive Eggbeater style weapon. Entered into the 150g Robot Wars/Battlebots competition in wollongong, we'll see how my machine does against strong competition.

Damn you Split! You cost me $4 in motors :P

if there's one other thing to do, tighten up those forks! they flutter a lot with the weapon vibration, which is common. mounting them fixed in thin, flexible TPU pieces with a bit of preload or adding small torsion springs to keep them pressed to the floor will make getting under anything and everything more consistent.

4wd semi-invertible 'drum' spinners have been a solid design choice for many years now. I remember there being a TON of them in the 12 and 30 pound classes back in the mid-2000s. Not much has changed since then.

A video on your CAD though process would be good

[@TrentSheather]

It would be cool to see a breakdown of where your weight budget goes for this and other robots. Perhaps a pie chart that shows the weight of each component and the mix of frame, weapon, power, and electronics elements.

you should fight cheesecake

[@Shovel________________]

i find it funny how just flopping around until you're back on your wheels is actually a viable enough self righting solution with how light these bots are

Every Aussie who isn't from SA knows that Adelaide is just a fever dream you get from crossing from WA to the east

I thought I heard Angus there

With this design you could switch to mecanum wheels and get another degree of control with side to side motion.

Let someone else win in Wollongong for once 😂

[@scotty6435]

Your driving control is absolutely phenomenal! Very measured but relentlessly aggressive.

Awesome winning streak. I like the design, and it seems very stable and steerable which is key to getting into the correct position for atrack

[@Hilshoist50]

Another great video James, keep 'em coming.

[@gerbil7771]

As much as you make a great little bot your driving is stellar. You out drove all your opponents thoroughly.

[@MGFDLR]

That thing is mega powerful, you hit them like a riptide 😉

[@PCBWay]

This is SO good, do more uploads pls! 👍👍

[@plasmapanasonic4741]

Very cool to see this sort of vid, from omeone whis thinking about tetting into the hobby

[@SethMarcell]

Very cool!
