UK Kilobots - 1.362kg (3 lbs) Combat Robots

f you can name me one robot from a veteran whose machine has destroyed its opponents without having any defeats or damage done to itself in recent years

i agree with dave here we should make this weight class full combat all the time and also we aren't making open walls, a pit etc so a push bot wouldn't be right good in a fight anyway, the assault course we are allowing the robots to be mod'd in anyway (but still be in the rules) like taking the armour off and putting bigger wheels on and so on, to be able to go up ramps and over different surfaces, the course will be timed lowest time will get most points and also we are looking at putting short cuts in like swinging doors and things like that and will be changed every event so a route can't just be remembered

Guys guys this talk is too much! You don€™t have to worry about the weapon, no weapon thing this is wiped away by one simple fact.
Robots eventually €œEvolve€ to suite the environment, the key is not the rules, what to allow or reject, but the arena type, if you want spinners to reign in this weight class, make sure all arenas are full combat with no pit, flip out zone or any other distraction. Then its quite simple if you want to win build a robot with a weapon and it would probably be a spinner! If you want diversity then change the stakes, introduce a different environment and the battle results will change.
If someone brings along a boring box put it up against a spinner then it won€™t be boring any more.

That's just a single fight though Gary. Yeah, sure there have been single fights where someone has destroyed their opponent with no damage to themselves, but there's no one who it happens to every single fight, who is guaranteed to come out working, as suggested.

So, what are people using for motors/wheels/batts etc?
I guess I should probably experiment myself, seeing as with ants, feathers and heavies everyone pretty much knows the best parts to use whereas ideal components for this class have not yet emerged obviously. Will be interesting actually to see what motors, speedos and battery types come out as the best for cost/effectiveness to weight as machines develop.

I'm thinking of using this robot as a bit of inspiration:

and then scale it down and alter it a bit so I'm not completely stealing a design. I don't have the tools to custom make gearboxes to the degree of quality he does but I quite like the way it looks

I was wondering about these motors at 6v

the wheels i don't know but probably small ones!!!

I have those motors, and that controller, have used them in ants on 7.4v.

[calumco]

those motors and the speed controller are fine, im using the 30-1 motors, u can also buy the motor holders aswell, aswell as wheels which go straight onto the shaft

http://www.technobots.co.uk/acatalog/Sh ... s_420.html - bottom of page for wheels

http://www.technobots.co.uk/acatalog/Sh ... rs_81.html part number 1451-100 for the motor holders

although on the motors you've chose im not sure if the holders would fit onto them because the little gear box is twisted and not inline with the motor if u get my meaning

[RogueTwoRobots]

I looked at those motors but I'm not sure if they're a little underpowered or undersized for a kilobot. So any experiences/ideas of how they might perform would be appreciated
The only experience I have at that weight range is super-antweights, just using servos and receiver battery packs. So I'm trying to imagine something four times the weight of that. Servos might cope but would be slow to move unless speed-hacked.

I was also looking at the Technobots range of MFA motors, like the ones used in Zeobots/Battle Ratz but some of the smaller versions. I remember seeing a few machines using them at the UK Robotic Games back in 2006 for the 3kg sumo class and they were quite a good speed with what seemed like decent torque. Haven't looked properly into the weight of them yet, but compared to those 6V ones Craig linked to they'll obviously be heavier. Also means the possibility of going overweight more easily, as the bigger motors will need bigger batteries.

But if those small motors can cope with the weight, could mean plenty of weight for a decent chassis and weapon. Several things to consider *ponders*

EDIT: Just seen Calum's post, so if they are fine then that could be a six-wheel-drive lightweight chassis sorted :-)

I think those motors would be a little bit weedy under a kilo of weight. I mean, if someone's using them and they're fine, then I'll go with that, but I managed to damage one of the gearboxes just by trying to get the wheel off the axle once, so I'm not sure if they'd do. Maybe if you had six...lol
