do you mean 6 in each robot?, i mean if your still on about your clusterbot idea i dont really see the point in 6 i would say 4 max
i have got a really fast setup at the moment, 18volt drills running on 24ish volts NiMh 3200 mah i think, but if you used 9.6 just halve it
and you only need one speedo per side, so just two per robot depending on what speedos though

Featherweight Envy- Envious?
i like envious. i will start to build one. feather envious will be here very soon. :)
Excellent. Mines a Guiness...
:wink:
got a very interesting design for envious flipper. will reveal when i have done more homework.
What is more powerful - 6 14.4v drills or 4 150w golds?
If golds are best,can anyone suggest the gearing that would be best?
Can 2 25amp sonik marine speedos power 4 golds?
What batts would be best for golds?
These questions are not about a clusterbot,they are about my ideas-im comparing them to see which will work best.

12v golds by the way.
For the golds, it depends on what voltage you ae running on. 12V golds on 12V are about the same speed as 24V on 24V give or take. DB5 runs them on about 9:1. Stiff Breeze runs the 12V on 12V and is about the same reduction maybe 7:1 ish, dont know exactly what the ratio is, but this is a guess from looking.
But I would say that 6 drill are more powerful but less reliable. Most people burnout or damage a gearbox every few events at least, so if you have 6 motors then you are gonna be buying a few spares. The motors and gears that I have in DB5 have been in it for 3 years, the gears are slightly worn but still not slipping. The motors have lost some power for sure but as I said they are old.
I dont believe that 2 25amp sonik speedos will handle 4 golds, in theory if that 25 amp is a continuous current rating they should. But I wouldnt bet on them. 24V Golds draw less than 7amps each, but the 12Vs will draw 12.5amps so you will be on the limit with the 12V version.
So I would recommend the golds (24V) but thats what Ive used for years.
I recommend the 24v golds as well, i ran them in Alpha for years, now theyre running in Omega, great motors for the price. Ive always ran on the Electronize 15Amp CPU controllers.
Would these be good for 6 x drill motors(12 - 14.4v)/4 x golds?(24v)

I think, that the max discharge Rate is to low.
I youse Sony RC 2400 (nicd)
and Sony SCR 3300 (nimh)
Discharge Rate up to 60 Amp is not a problem.

Thanks.
sorry,
I mean sanyo not sony.....mea culpa
the new armour for psycho fling is half complete, 3mm stainless i think will shine like a mirror
the company that is help is http://www.stedmark.comwww.stedmark.com
very helpful,quick and talented
the new armour is complete, ill put some pics on my site as soon as the internet is working properly.
anyway the armour is all 3mm stainless, new box section frame. it consists of 2 side pannels which each consist of one side 1/3 of the top 1/3 of the back and 1/3 of the front. then in the middle a lifter pannel. each side weighs 2.3kg and both sides are held in with 64 bolts
look forward to causing some damage for once not taking it!
Ive nearly finshed the design of my new featherweight, as yet unnamed.
I thought Id ask peoples opinion before I start cutting metal.
Heres a cad render: http://hyperdynamic.co.uk/images/robots/Iso.pnghttp://hyperdynamic.co.uk/images/robots/Iso.png
and heres more information about the design: http://hyperdynamic.co.uk/NewRobot.htmhttp://hyperdynamic.co.uk/NewRobot.htm
Please let me know what you think. Current weight, as modelled, is 12.5kg. It seems a bit on the light side to me, given its 10mm angled polycarboante armour and 515mm across the diagonal.
For the name, Im considering Loki. I might change it to Loke (pronounced the same) since there used to be a Battlebots team called Team Loki.
Cheers
Mark
looks good
id like an axe but seem to be one of the hardest to make
if you want it as loki more then loke im sure you can - its not on TV so there shouldnt be a problem
Well, i havnt had time to make a proper feathweight since turbine 3 in 2002. so i thought id try get back into it. heres the spec of my new robot for people who couldnt make it to thinktank.
Name; 360
Current weight 10.18kg
weapon; 360mm, 4.315kg disc, turning at about 3000rpm (maybe more) from a custom 4hp drive unit.
drive; bosch 35w skid steer, belt driven to whyachi wheels turned and dished out on the front to some slippy wheels on the back with grade 5 titanium axles (exposed wheels)
chassis; lazer cut and welded 2.5mm grade 4 titanium
selfwrighter; coming soon, astroflight powered.
speedo; currently a Sabertooth, upgrading to a vantec soon.
radio; currently a DX6, hopefully swapping to a DX3 with a buddy box for the weapon, (if i can mod it to failsafe)
armour; 2.5mm titanium, hardox front plow (when ive made it) and 3mm alu checker plate.
notes; mini hypno
pic on profile :) vid of it driving onling later tonight or tomorow, hopefully a vid of it spinning within the next week.

MMM nice will have to give it a bite sometime :proud:
yeh looks really good, is everyone building look alikes now LOL
People saw it at thinktank so i thought i might aswell post the specs of it,
Name: Flow!
Weight: 10.4kg
Armour 10mm ali
Drive: bosch 35watts running on 63mm blues
Speedo: 10a sabertooth
Power: 4 cell (14.8v) 2170mah flightpower lipo

Even though theres a lot of tweaking to do on it Ill give the updated specs of Drumroll now that its fully functional:
Name: Drumroll
Weight: 11kg
Power: Two 9.6V 3700mAh Ni-mh battery packs connected in series for 19.2V
Drive: Two 12V cordless drill motors overvolted to 19.2V and connected to 75mm blue wheels
Weapon: A 3mm thick stainless steel spinning drum with two hardox 500 grade teeth welded on. Connected via timing belts and pulleys to two HTI motors also run at 19.2V. Current ratio is 4.8:1 but will be getting reduced to something in the region of 2.5:1 or 3:1.
Control: Two Electronize 15A speed controllers for drive (may upgrade to Scorpion or Sabretooth in due course) and a Victor 885 for the drum motors.
Armour/chassis: 20mm thick Nylon 6 sides and bulkheads, 3mm ali base, 4mm hardox rear wedge and 6mm polycarb top with 3mm polycarb self-righting hoops.
Notes: Finally made an outing complete with drum at Robochallenge Thinktank. Didn€™t do badly but didn€™t excel so some fine-tuning required before its next event.

Hi Jamie so how do you find the HTI motors
I might as well add our latest one
Name: Aftershock
Weight: 15.8kg (new shell coming next year)
Drive: 2x 18v drills running at 24v on 75mm wheels
Weapon: FP Flipper with 32mm bore 50mm stroke ram (from cutlet)
Speedo: Scorpion XL
Armour/ Chassis: 2mm steel box, 1.5mm welded steel all over with polycarb base
Notes: Finally working after 5 months of talking about it. Ran in the whiteboards at thinktank and flipped 3 out of the arena:proud:. Also needs to lose 2.2kgs of weight which means a new HDPE shell is needed.
There is a very old pic on my profile.

Tony, I dont feel they got a decent run-out at the event as my battery packs were never performing to the best of their ability. This was mainly due to me only getting them charged for the first time the night before and then topping them up with fast charge twice on the day. So Ill need to cycle them a good few times well before getting a clearer picture of how the motors truly perform but I am happy with them so far
Hannibalito I-5
Yet again a re-incarnation of this old hand.
Weight: Currently less than 12 Kg.
Drive: 2 speed 900s capable of running 7.2-40V ,90mm wheels. Top speed @24V 50km/h
Speedo Scorpion XXL
Weapon, the old 32mm bore X 75mm stroke ram that forms the heart of Hannibalito I ,with steel buffertank and 12 oz CO2 bottle.
Chassis. Steel T-Form Chassis, common for the Hannibalito class robots.
Armor, 10mm HDPE bended and welded into a shell.

Isnt it a little bit steep to get under anything Mario?

Thats without a scoop Dave.
Thats still to be welded on. But with kilos to play, I dont see the problem

there doesnt seem to be a pic on there matt
dont think its working
Scrap my last comment about the HTI motors seem to be performing ok. Burnt them both out today when demo-ing it for some family members. Think I may look at speed 900s going through a gearbox before the belt stage as an improvement. Other than that, the drum span well with them.
What is the situation with speed 900s I thought they were now discontinued?
thats what i heard and does any 1 know a motor with similar specs to the speed 900 which is around the same price
It seems you still can buy m.
We just bought a nice supply of them, just to be sure.
We have 12 spares then.
In the end ,its just another Johnson motor.
i only have 2 spares for each robot maby i should order some more do you think a mini ev motor would be as good as the speed 900
Graupner have now stopped making them, and most UK model shops dont stock them anymore.
