Team Hectic possible featherweight build.

Postby Hogi » Wed Jul 06, 2016 2:18 pm

Hi everyone, I know this is more of an antweight sight but I know a few people on here also build featherweights and I might have a go myself as a long project over the next year or so. If anybody could post me some links to decent featherweight components EG: good drills to get motors out of, receivers, ESCS, wheels, etc. I am planning on using an orange transmitter as this has mixing on it so that eliminates the hassle of installing some kind of mixing on the robot. Thanks guys.

Dan.

For motors you can't go wrong with the cheapest drill in the argos catalog. Many feathers use them and they work really well with some ~100mm wheels for the right speed on a 3S LiPo. Receivers I just keep using LemonRX's. ESC's these days are often reprogrammed TZ85A motor controllers due to their sortof robust nature though there are other options.

Ooh, awesome :) Yeah, you'll want some Argos Drills for drive likely; they're what most people use for simple feathers as they are nice and cheap: http://www.argos.co.uk/static/Product/p ... 112946.htm

They need hacking for use as drive motors, but there's a video on how to do that here (the whole series is quite good): https://www.youtube.com/watch?v=8_kWYewQmV0

Controllers used to be just buy a TZ85 from Ranglebox but they're out of stock atm. Not sure what other options there are for that.

2.2Ah 3 cell Lipo is about what you need and they're fairly cheap from Hobbyking.

Thanks guys. also, how do you connect the battery to the robot? I wouldn't imagine you'd just plug it into the receiver would you?

Also, I've been told these are good, what do you guys think? : http://www.ebay.co.uk/itm/181744005899

And also what about these wheels: http://www.active-robots.com/100mm-wheel

No and no I'm afraid.

2 of these http://ranglebox.com/product/botbitz-30a-brushed-esc/ will do drill motors.

as for wheels https://www.youtube.com/watch?v=AcIIUGBJzJM

I don't have a drill press or a source of hubs so I reckon I'd struggle to make the wheels that way. what about the banebots wheels? I've heard they wear quite quickly but are otherwise ok. http://www.banebots.com/product/T40P-295BA-HS4.html

Also, will this lipo do the trick? http://www.hobbyking.com/hobbyking/stor ... LiHV_.html

Those are a bit overkill... something like this is probably more what you want: http://www.hobbyking.com/hobbyking/stor ... duct=26715

Thanks Rory. i'll get one of those. It's looking like this is likely to be quite a long term project due to money constraints but I should be able to get it ready for Portsmouth robot wars live show 2017.

Also, I've been doing some more searching for decent wheels and I found a link to a site on the FRA forum that sells these 125mm diameter wheels with tyres already on them: http://www.bearingboys.co.uk/Poly-Tyre- ... eel-8695-p

opinions?

Bad. Too hard no grip. Also a tad large for fragile drills

also with banebots wheels you'd still have to get a hub together and pay america postage + customs and all that jazz.

i like these for simplicities sake. If you want I can make you drill hubs i've done a few for people now. Come to think of it I've got some hacked drill motors + mounts if you want them. Send us a message if you're interested.

I now have a pair of drill motors that will be Hacked at the AWS. I've also just ordered the plastic for the body and the wheels.

I'm a big fan of bike tyre screwed onto whatever fits on a drill motor for wheels, Works really well with plenty of grip.

Great idea Alex. I'll find a cheap bike tyre and do that. :)

I was thinking of doing an axe bot using a 250 watt scooter motor from ebay but I could never find a suitable ESC to run it.

This is my preferred tyre, the chunky tread lets you put screws inbetween the tread so you don't lose grip from them and it lasts quite a long time, Even used it on my heavyweight. You might be able to find it cheaper elsewhere though.

thanks. :) My HDPE and wheel hubs are due to arrive tomorrow so I should be able to get to work soon. I'm really looking forward to it. :) Building this robot should give me something to do for the 8 weeks I now have before going back to college.

If you're looking at doing an axe, have a read through the build diary for Hatchet 2: http://www.fightingrobots.co.uk/threads/12553-hatchet-2

(Edit, Hatchet 1's build diary is also worth a read: http://www.fightingrobots.co.uk/threads ... ring-brick)

The largest scooter motor you can get that'll fit easily is the 350W ones, so probably go for those rather than the 250Ws, As for ESCs, Electronize 30A, Victor 60A, or TZ85s all would work, but they are getting harder to come by these days...
