Or instead of building one roughly the size of an xbox controller, you could build an antweight? So you could go to events with it?well, the size of an xbox controller could be better in the sense that he gets practise driving and building, before he challenges himself with the task of building an AW.
would you like you robots to be flipped and collapse with cardboard armour, or comparibly strong with wood armour?I have some pretty thick and strong cardboard. ;D
I have been thinking about making a pair of robots from cardboard, a pair of flipper, little more than the size of an xbox cotroller, if possible. I was wondering what the cost would be, what tools I would need and where to get the parts. Not for any competition, just to mess around with. Like a cheap version of AntyB, if you have ever seen that, but a more generic flipper design.Anty B? I remember this one. Didn't it fall under the Floor Flipper in its first antweight battle?

first off, dont evern bother with cardboard or wood, dont you dare!! get a sheet of polycarbonate off ebay for like £4 (can be cut with scissors)Yeah, cardboard is too weak, thinking of using wood, we have plenty nicely cut pieces in our attic. May also use polycarb, will consult with father this weekend.
for drive get a pair of cheap £2.50 servos of giant cod ( or get them modded or speed hacked from me) and a basic 2.4ghz kit which is like £26 now, batterys are about £5 or £6 depending, and the weapon servo will be from £5-10.
build an ant, not something you can't fight
you wont need a soldering iron for this robot.1. But how do I connect the various wires?
why wont you fight in competitions??
where do you live?
Why not get your friend to take you there or something?None of my friends do robot evens, but they enjoy the models as I do.
And that '2.4 GHz kit' is the controller, right?
yes, the 2.4ghz kit is the transmitter and reciver.Transmitter being the actual controller, right? And does it have a button for the weapon?
rc cars and toys are sod all use im afraid
it is a 2 stick transmitter, one for drive, the other for a weapon, a button or swich can eaisliy added, like this done to my dx5e:So all the movement on the robot is tied to one stick?

the transmitter is the bit you hold, the rx picks up the signal

TRB sounds like he just wants to build some robots that him and his friends can fight with, nothing competitive.

It's all plug and play. Connect the PWM wires to the receiver and go.Nice. Can you give me a link to where I could buy these parts, or at least their names?
here is the listThanks a TON!

Hey, I see you're trying to make a new fun hobby. Let me fix that for you.Get out.
DPAn actual small hinge?
Would sellotape work as a hinge for the flipper? If not, what else could I use?
DPNo, you will need to make a hinge
Would sellotape work as a hinge for the flipper? If not, what else could I use?
What I'm planning on is trying to make it an AW with the stuff I'm getting, but if I can't get it to 4"x4"x4" or it is over 250g, then I cba to re-make it.Gotta be within 150g, FYI
i would go for 1mm polycarb, anything more go hdpe. reason being that it is very soft at 1mm thick (or thin!)Which is why he shouldn't use 1mm
cancel what?The bot building.
Not as cheap as polycarb, I don't think so anyway.But it's better that polycarb, IMO anyway
But I don't have the tools for HDPE, so it doesn't matter anyways.lol, you can cut 2mm hdpe with scissors
2mm HDPE can be cut with scissors?Easily
it shows scratches and glue marks thoguhIt's much more brittle also
while we are on the subject of hdpe, the white stuff is fine i have foundNope, much more brittle than the black
not for me, got a 4mm sheet of the stuff and it seems exactly the same if a bit stiffer
That's what she said. :trollfacewhile we are on the subject of hdpe, the white stuff is fine i have foundNope, much more brittle than the black

That micro servo you're using for the lifter isn't going to do too much. You need at least a standard size high-torque to get any decent lifting power.Thanks for helping!
I've built some stuff before just messing around, and anything less than a standard servo with 200 oz-in of torque won't lift anything. They're designed for steering in Ready to Run RC cars and control surfaces on 40-size aircraft, and usually neither of these require much load.
Keep in mind that the longer the lifting arm, the less torque you'll have at the end of the arm. You could be able to get something to work if you have an exceptionally short flipper, but otherwise you'll definitely need an upgrade.
As for that drive servo, it will work but in general constant rotation servos are slow.
don't bother with standard size servos, too heavy.Like this?
look for a metal gear servo, about 20-25g with about 3kg of torque, will run you £20 at most, more likely £15.
Please don't use servos for drive, you'll be literally driven around in circles by faster bots.I'm not going to be completing with this thing, and if I need to I can switch out later. The thing is that motors need tools. The most sophisticated tools I have available is a pair of scissors, and a saw if needed. Servos can be plugged directly into the receiver, so they're ideal for me.
A pair of tiny escs from finger tech only weigh 4.5 grams each, and a pair of gold sparks(also from finger tech) weigh 28 grams each.
That adds to about 65 grams. If that's too heavy for you, this gear motor would work fine: http://www.robotcombat.com/products/0-GM11A.html (http://www.robotcombat.com/products/0-GM11A.html)
Well, if you're building something that small, then go for a high-torque micro, but make sure it's a high-end one. You'll still need around 150 oz-in of torque.Are you sure? Everything I've read about AW lifters/flippers like to servos with less than half that.
with 7 cm wheels, servos are fine for a beginer.OK, I'll probably get that then. Anything on batteries, so which drive servos?
you can always speedhack if you feel like it, you will have no pusing power
understand the fact you want it controlable, good to practice with, then buy motors.
hang on, i could have sworn you live in the uk? Yep. and are building a 150g ant? Yep, well, I'm not sticking to the rules too strictly.

flipper servo
Please don't use servos for drive, you'll be literally driven around in circles by faster bots.The fingertech motors are far from ideal for a UK ant. They are too big and too heavy to be practical to use, and would force either extra gearing for 4WD or staggered wheels. They are also only available from the US. Ordering components from outside Europe is not preferable when you're only building an ant, especially since he doesn't want to compete with it competitively.

Thanks for the great info, yet again. And what luck!

Anyway, I agree with haz on regards with the weapon servo, either that or the HPXF for an ant (I personally prefer the HPXF, but both work well). It you do want to use servo drive, which is wise if you don't want to use it competitively, I would recommend the SG90 servos from GiantCod (http://www.giantshark.co.uk/towerpro-sg90-micro-servo-p-268.html (http://www.giantshark.co.uk/towerpro-sg90-micro-servo-p-268.html)). I have not used them, but according to all accounts, they are easy to speed hack and, though can wear out, are not expensive to replace.
It's really not powerful or 'well made' enough to take the straight of being a weapon servo. The HPXF or HS-82MG that Haz mentioned would be much more suited to that role.Thanks for the great info, yet again. And what luck!

So, a friend from school and I have been talking about antweights, so I'm going to try to finish this thing. He wants to make an AW as well.Use a Lipo, think Hobby King servos, yes they can handle the volts, there you go.
So, all I need to know now is which battery pack to use and which charger to go with it. Should I use LiPo, or NiMh? If I use 7.4V, will the servos die? Etc.
I've settled on a Blue Bird BMS-380 MAX as a weapon servo. The cheapest I've found it for is £24.99 -shipping. Shipping outside the UK isn't really an option, long story.
IIRC, all I need are wheels, batteries and the other drive servo and the weapon servo, right?
OK, and what charger do I need to go with it? I understand that if you get the charger wrong on LiPos they tend to get very dangerous very quickly. I know I need a LiPo charger, I'm just not sure on which one to get.I would like to disguise this post so it doesn't look like a blatant bump, but I CBA.
