ReLoader: 150g 3D Printed Battlebot build
Вставка
- Опубліковано 10 лип 2022
- Having a crack at rambling over outdated camera phone footage of me transferring the guts from the prototype to the finished article for my 150g Antweight robot called ReLoader. All being well he will debut at AWS64 in Bournemouth on the 30th. I aim to have a full team and will try and do a small video on each to try and learn how to suck marginally less.

What an impressive and neat build. I've heard people say that good cable management isn't possible for 150g robots, but you've shown that it's not true at all.
Thank you! There's always time for cable management - the trick is to give yourself so little space you have no choice but to have it fairly neat
The precision of this design is incredible. Every single tiny little part fits perfectly in its slot 😲
Fantastic build and video.
Very excited to watch this!
Nice quality builds.
Would love to see this style of video for any of your pneumatic 150g bots
I can look into doing this as I still have the 6wd flipper. Can't say what sort of timescale it would be done on though. I have some information on my FB page 'Harry Makes Things' that covers some of the components and basics
Cheers!
Nice video bro.... I'm also working on a wedge with flipper bot... I made 25 kg wedge bot with a empty slot in the middle for the flipper Similar to yours( didn't had time to finish, not even had time to figure out the errors in the control system, so had to turn it into a wired bot overnight) the bot went to fight as a defensive wedge bot....
Now planning to add the flipper mechanism....
Thanks! It's always a shame when you don't get to fight with the bot you planned. At least you got to test your drive motors so you have a more reliable platform for when you get your weapon sorted. Best of luck for next time!
Very nice work! I'm curious as to how you stopped the chassis from warping underneath because I've been having that problem with my own four bar lifter antweight ^^;
Thanks for the kind words! Nothing super special. Just making sure the bed is properly levelled and you have an enclosure for ABS or making sure you have no drafts passing through for pla etc. I level the bed with feeler gages instead of folded paper, business cards and so on. This is much more reliable and repeatable. Sometimes I will also print things on their side so its a really tall print with a smaller footprint if the geometry calls for it or its a difficult material to get to stick (e.g. nylons)
@@HarryMakesThings I always thought it was because the base of my build was only 1mm thick ^^.
Might just be me, but the video is super quiet. I can't understand anything (on Android)
Thanks for the feedback! Likely that's an issue with the video rather than just you. I'm not exactly competent with media and such so it's still baby steps. I'll try and make things louder or clearer in future, cheers!
@@HarryMakesThings Yeah! thought I'd mention it because it would be sad if nobody could hear it! Good luck!
I can only hear at max volume. Commercials are painful.
The sound is fine for me on an Android.
I'm guessing the Malenki nano HV will allow you to simplify your electronics now (assuming it's still running)
Yes and no. I would then need an additional BEC to run my servo. My current plan for this line of robots is ditching the servo and running geared motors on the malenkis 3rd channel to power the lifter which would remove the need for regulated voltages.
I am curious about those custom n10s. Do you have any info on those?
Yeah for sure! I found some really stubby (shorter than a regular N10) motors that had a decent stall current and speed. I painstakingly pulled apart my cheap n20s and swapped pinions. Downside of these tiny motors is there are no mounting threads so they're just glued on to the gearboxes. The motor shafts also have to be clipped down too. I think I bought a bag of 20 for about 7 pounds and and the donor N20s ran me about £1.20 each landed. I'm pretty sure there are some photos of this setup on the Harry Makes Things Facebook page.
@@HarryMakesThings thanks very much for all the info!
where can i find the file for reloader that thing looks cool
sound is so low can barely hear
Yes, my mistake. First time I tried making this sort of thing. Think I fixed the sound for future videos
Any plans on releasing stls for the flipper?
I'm in two minds - not that I'm particularly protective of quite a generic design it's just a bit of a ball ache to assemble and work on and that could prove frustrating unless you use the exact same components (some being custom) and I cant realistically provide the support needed. It will probably serve better as a general reference (or "How Not To Build A Robot) guide!) than print and assemble.
How thick are the various bits of titanium?
1.2mm!
Are N10 motors happy at 11.1V? I thought they are rated only for 2S voltage.
I have run them at 4s before - could I do it for a couple hundred hours? No. For 3 minutes at a time yeah they'll be right. Components in combat robots have a short, hard and ugly life. I'll happily overvolt motors. You just can't get away so much with electronic components like escs and rx's.
@@HarryMakesThings thanks, so those are 6V versions of N10?
After leaving the comment I found some 12V variants on Chinese websites.
I guess you are right with short combat life, I reminds me about WW2 tanks from Germany having parts rated to last years when combat life was just few days.
Hey how many rmp are your N20 motors rated for 6v
I use between 500 and 1000rpm depending on wheel size in my ants. These were 800rpm I think.
Great thanks I have 800rpm n20s on order
Please help me to know what exact dinamo is that in your video?
The drive motors you mean?
The drive motors you mean?
Where do you buy all your parts from online
A lot comes from the bristol bot builders webstore, ebay and AliExpress.
Hey man I'd love to download your stl files for Reloader. I'd provide a tip too. You won't need to provide support I just would like to put it together and mess around with it. I've built small robots before but I like this one as it reminds me of biohazard.
Hi, drop the Harry Makes Things page a message and I'll see what I can do.
Hello, very good, I congratulate you, excellent work, could you send me the stl, thank you very much
Your switch is the wrong way around!
Time for a sharpie correction! That's from the V1 wiring loom hah
