Export in polylines!
I flatten the plates to just be the profile of them (ie 2D of every plate) and export as dxf in polylines. Polyfaces is never liked by my machines or others.
I spare weight by drilling holes in the gears, if they don`t turn as fast as a couple of rpm it should not be a problem.
You have to leave a couple of mm material around the holes.
That’s not a bad idea.. he said he used Autocad and there was no entity in the files so I have downloaded the free trial to see if I can fathom it out.
Without having to necessarily learn to use other software, might be worth downloading Fusion 360 so you have something you can check the files against (i.e., if you can open the DXF file in F360 then...
Hi again, here for some more help if that’s okay. Hahaha
Of all the available free CAD software, I chose Sketchup to learn and do my designs on. (slight regret now).
Now I come to get my weapon...
Lathe to remove weight from the gears sounds like a good plan. It's not the most efficient in terms of strength-to-weight ratio but it does mean you keep everything symmetric. I guess drilling holes...
Damn right!
Great write up, and congrats on the last fight. I was properly on the edge of my seat while Léim was single-wheel-jiving over to ZG. :mrgreen: Looking forward to seeing what you take...
I used this page while wiring mine up: https://thevariableconstant.blogspot.com/2013/05/thrifty-roboting-vex-motor-controller-29.html
That there be Jamison Go's blog, so I think we can be assured...
There are two kinds of shafts. There is a dead shaft, where the shaft is static and the gear slips around the shaft or has bearings inside the shaft to allow it to roll and then there is a live...
So this quick update is mostly to ask about gears, sprockets, and how to mount them, but first, an update on the new machine. Barróg Doom should be constructed a lot quicker than the original, with...
Applications: http://bugglebots.com/apply
Bugglebot returns for 2019! Think you have what it takes?
Applications are now open to compete in the next series. There's two months to apply, so...
That would be great! Thank you! Do you need any info like the amount of teeth etc? or is the pic good enough? Ill cover your postage too if there suitable! :)
Will :)
Thanks for the info! It was the gears closest to the wheel so I assume its just taken a big wack at some point in the final fight! I shall look around for some job lots xD
Yea, i was going a...
Will, i may have some gears from some old drills i scrapped at work, will see what teeth they are and i can send them over to you if they match and if your interested :)
Now that the rest of the Bugglebots specials I was in have come out, I can finally finish off this event report.
FIGHT 3: DUNG BEETLE MELEE
So even though I was out of the main competition, I...
It's back after 20 years! PIECE DE RESISTANCE
Well in spirit anyway-I have made a homage to my original creation in the
Form of a featherweight with bulging eyes and a robot driver in the cockpit...
We are very glad to announce Mad Metal Machines Vol.25 is going to take place at the Intermodellbau 2019 in Dortmund (Germany).
Like last year there will be a competition in the Raptor- and...
Yup, well done us! :proud:
Unfortunately not the first time I've kicked up a fuss on here about something stupidly obvious & probably not the last either.
Well after taking BOB 3 to Robodojo, I can happily say for the first time I didn't have any drive problems like the other two.
When I got there BOB 3 was still not finished, still needed to make a...
Thanks for all the feedback. Confession time... As I went to swap in a new receiver, I noticed that the leads were plugged in the wrong way round. I've put them the right way round now & it works...
I've had this happen to me with Shu! where the end stage planet gears just got stripped. It wasn't that the motor was being overvolted (it was a 12V motor running on 9.9v), it was the load on the end...
I've occasionally seen a joblot of "spares or repairs" drills (argos and others) appear on eBay. As Lucy says though, you need to make sure you have the same type all round or you'll go in circles.
...
I'm no expert but I do believe that gearboxes are supposed to have teeth lol
It appears when the motor seized or during an impact it sheered a few teeth lol but the gearbox (apart from the outer...
The odd thing, I find, is that I can't get the gearbox on their own. I guess it's probably more economic to simply get the whole assembly premade than it is to have the parts shipped in separately....
Yea xD I shall try take a peak in the next couple of days and see!
I'm guessing it's harder to get the standard cordless drill gearboxes new? Because I haven't really found any online. I was...
Ah, I had forgotten one of your gearboxes has broke. I'd open it up and see what's going on in there first but for a replacement box, it might just be more economical to simply replace the gearbox...
Update time!
Azriel
So the bodywork is kind of together and the wiring loom is in. It all works! However, once again, it's too heavy by 100mm. Ultimately, it's the polycarbonate causing the...
That's great thank you xD
I'll have to see exactly what failed on the cordless drill gearbox and if it's a plastic bit I'll see what I can do about a beefier metal one xD Either that or maybe look...
No worries, gotta learn somewhere! ;)
Chain drive... Deathly Hallows did a chain drive for one of his Featherweights (and did a build diary here) which shows an implementation and I know at least...
Yea, sorry I'm not very good with the terminology!
I mean just having the wheel separate from the gearbox maybe chain driven to take the strain of the gearbox itself from having the wheel directly...
Hmm, I'd fetch him on Facebook if you can, but he's been pretty responsive to any of my PMs.
Are you sure the Rx is binded to the Tx, and have you tried swapping it for another one? That may be...
Technically the gearbox on your motors is a drivetrain. If you mean spur gears, I don't personally think it is worth it with the motors you have now. If you were running brushless or bigger motors,...
Yea xD It turned out well though!
That's exactly what I have been thinking of doing but again not sure if it's worth it. I had an idea about mounting a bearing into the shell of the bot and having...
Hey everyone
I've wired my dual channel FeatherTwo into one of my bots & it doesn't seem to pick up signals from the receiver. As far as I can tell the receiver is working perfectly fine (a...
Aye, there'll be other events. Just a case of bad timing and missing parts. I've got Azriel running and will update tonight on that.
4WD isn't possible with the tooling I have here (I lack...
