I'm planning a FW smidsy but am unsure as to if I should stick with 4 drill motors at 18v or use 2 speed 900's?
Trying to make it more like the RW smidy with the lifting scoop but I doubt I'll run it with a disk unless someone can make disks that small, yet would probably be so small that it would be ineffective
2 speed 900s or 4 gimsons :)
*drill motor type motors ;)
4 gimsons, i use 'em
Hats the benefit of those over 2 speed 900's?
4 gimpsons would do fine and be easiest
Beauty 2 and iv use 2 x speed 900s
is all depends how good the weapon is realy
It's main thing with it being a FW smidsy is it being a good rammer, so I just can't decide which would be beast too use, one motor per wheel but weaker, or 2 motors for 4 wheels but are stronger motors
if i was to make a rammer (BORING BOX) ups i would use 4 speed 900s
Boring box WITH A LIFTER! :lol:
It's probably one of the only big EW bots not made FW, trying to make a FW and ant version of it (eventually)
Gimsons all the way
with a 100mm actuator also a gimson
also there wheels a SMIDSY esk, make it small and make it in metal, O and get the dude who owns SMIDSY to measure it so you get the proportions right
http://www.gimsonrobotics.co.uk/GR01_pl ... motor.html bargain at £25.90 each
http://www.gimsonrobotics.co.uk/GR01_pl ... motor.html you wont look back
matt does own smidsy, scary i know :wink:Quote:

Haha, it's scary how I own a big spinny thing, bust turned it into a big rammy thing and will make it into a big lifty thing :lol:
So the view seems to be 4 gimson's?
you won't regret it
But, for a rammer, would it be strong enough?
yes.
stronger than drills
Yes they will be and you're building a lifter, reference old Style SMIDSY, which used Jaguar actuators, so not just a rammer, but a lifter rammer
Names for a FW smidsy?
Even four drills can make a decent rambot, more so if you over-volt them a bit. But the build quality of the GR01s is considerably better (in my opinion) to bog-standard drills, so they'd be more suited to a rambot.
Speed 900s would be more reliable still, but you would have to sort out some form of gearing obviously.

Perfect ceri, and so smidsy cysm has been born, work shall start after whitwick on it and should Hopfully be ready for the champs, screw a spinner, that can wait till next year ;)
I can't quite tell if that's a robot name or a generic Welsh phrase :lol:Quote:

Gimsons look good, but don't knock drills. In it's heyday Prodigy ran 4 drills on 75mm blue wheels and was as reliable as anything :D If I can actually find/afford a ESC that can handle 4 motors I will most definitely be bringing it back.
I'll try and get it ready for the champs but I'll probably end up doing it for the HW champs, may even get ant smidsy for then aswell, are all going to try and be as similar as possible
Probably end up using 4 drill motors due to cost and ease of purchase for me but over volt them and 30a esc's on each wheel should solve that problem
a 30a per side you mean?
I run 12v drills, 4 of 'em, 100mm blue wheels, overvolted to 18v, 30a Electronize ESCs on each side. I don't have any other machines to compare by but even with just 8kg behind it for grip, it's a beast. Definitely superior enough to make an effective pusher. Does about 10mph too.
Cysm? ... How you pronouncing that? Sounds like love wee to me. :shock:
I would assume it would be pronounced Si-zum. How did you get semen from that?
I was thinking more along the lines of, starts with j... Ends in um... Few z's in there too
Just me then? Lol cool name bro
Personally, it is surprising that Explosion is a better pusher than most box robots, which really shouldn't be the case! I don't think that the Argos drill motors are really powerful enough (or reliable enough for that matter), and so I'd definitely go with a pair of Speed 900's.
But that's just my opinion
u can get bare units off ebay for about the same price as the cheap argos 1 and the much better build quality
anyone got a link to those speed 900 type motors off ebay for like £12?
http://www.ebay.co.uk/itm/300511267976? ... 1126wt_689
They seem like the best mix of performance and cost, sorting out my own gearing ain't too much of an issue either
@Peter, what are you searching to find bare units? I've looked in the past with no success.
Yeh I got some of the speed 900 like motors, and they were considerabily more powerful and better built, even if you have two Pairs of drill motors or similer, cos If one motor blows, then you basically loose all drive on that side, because the current draw from the damaged motor is so high that, the other cant get enough current (or the ESC cuts out or blows)
i just searched for cordless drill and set it to buy it now, i found a guy who was selling a load of 12v ryobi drill for £10 each ... there do about 600rpm and the chuck is more difficult to remove compaired to the argos 1sQuote:
