Going with 1B and .5mm instead of .2

Gonna have to see if i can use the makerspace CNC for a even and flat cut in on the underside of the topplate and if it can make it a pressfit

Now with the impactors in place there are only two steps till i'm done with the shell.
(1 i'm still deciding on)
1A : Drill out 1mm holes in the hardox magnet ring to bolt the topplate to the steel ring

1B : Carve out 0.2mm or so into the topplate's bottom then pressfit the magnet ring in and epoxy it with the highest strength epoxy i can find (without drilling said holes)

2 : Red loctite every single bolt

and then the true last step is to paint the ring

all holes are done and tapped (besides magnet ring)

Metal parts arrived!

Oh thats great to know! Now i can actually get to designing that PCB knowing i can use a screwswitch

Didnt see the beetle with the switch but as runsler said lets not discuss it here-

Forgot to update here-

Some parts arrived and now Im just waiting on the electronics and metal parts for Lo-Fi to come.

There are also some other changes and plans i have for Lo-Fi that i have to work on-

Bottom plate to be a PCB that will also help me distribute power across the whole bot without too many wires everywhere. Most likely will order the PCB's from PCBway. i also want to make a screw switch built in because it'll be safer than a link and a LOT more compact than 2 switches that will probably die (see them in pic below-)

Instead of buying brushed ESC's just reprogram a Brushless esc with the Hydra firmware thing so i can drive my brushed motors easier and save space

Instead of M3 Heat inserts directly into the print i will be using 4 hex standoffs and m2.5 bolts.
1mm Polycarb topplate
3D printed chassis (TPU)
PCB bottom plate
And just tighten it as hard as i can from the bottom and top so its sandwiched really well.

Hey, I am Co-Organizer of the Hack&Make, togeather with Simon.
Yesterday, I could research how registrations are set up in our platform, and indeed yours Underloaded is sitting there unanswered. Sorry for this. it is embarassing!

Oh no wories its fine! Im glad you could reach out to us in the end!

I'll come over to the entirety of the event (Saturday - Monday) since i live close by to the building and can help to set stuff up / take stuff down! :>

Hello Roboteers! I wanted to start a smaller Thread linked to the MMM event in Maker Faire Hannover 2024 where Roboteers can (if they want to) post a picture or two of their bots to show others what they're going up against and can have a look into what they could potentially face in a match. (No need for full pictures of the bot can be vague or sneak-peeky)

If you're interested in posting just send a picture or more of your bots. Make sure to not forget to specify which weightclass it is!

Ill start first with a Beetleweight

Hallo Roboteers! Ich wollte einen kleineren Thread im Zusammenhang mit der MMM-Veranstaltung auf der Maker Faire Hannover 2024 starten, in dem Roboteers (wenn sie möchten) ein oder zwei Bilder ihrer Bots posten können, um anderen zu zeigen, womit sie es zu tun haben, und einen Blick darauf werfen können was ihnen in einem Kampf möglicherweise bevorsteht. (Es sind keine vollständigen Bilder des Bots erforderlich, sie können vage oder flüchtig sein.)

Wenn Sie interessiert sind, senden Sie einfach ein Bild oder mehrere Ihrer Bots. Vergessen Sie nicht, anzugeben, um welche Gewichtsklasse es sich handelt!

Ich fange zuerst mit einem Beetleweight an

Will there be a competitor list of which bots are competing?

Das war ein toller Image-Film!

Ich verstehe nicht wieso nicht einfach beide benützt werden können.

Links verschweißen doch innerlich auch Hä? Die funken doch auch wenn man das bot an macht.

Da sind auch sehr viele bots die Tape über ihre links machen oder etwas das sie versteckt sodass sie nicht raus kommen. Ist das auch nicht ein sicherheits risiko das man das link nicht gleich raus ziehen kann ohne etwas anderes aus dem weg zu schieben/abreißen?

3 Personen

2 Beetles

I second this! ^

It will be a lot more easy to allow both and as stated if its a Shell spinner or overhead spinner it'll be a bit tricky to disarm/arm the bot with a link whereas with a tool you can just unscrew it at a safer distance

links popping out is a pain too

Do you use blheli esc? Try lower timings.

I use a AM32 ESC

Though i will keep in mind the lower timings when i finish it and test it

Just making a custom hubmotor ring spinner after seeing Wajoo in person. That bot was incredibly awesome and really wanted to make something similar as that incredibly flat bot

There were no super flat motors i was happy with and my grandpa gave me some harddrive motors and after a little bit of testing i found out that i can easily convert it into a hubmotor (Though i have to change almost everything in it so i would just say its a fully custom motor at that point.)

Its a little sad i can't really send a video of it working but the motor KV is around 1500Kv~ And it is pretty darn strong and fast which i was super super happy about.

Some Info about the motor

Stator:
15 Poles
0.3mm Enamelled copper wire
25 turns per pole
125 turns per phase
375 turns total
42mm OD, 2.5mm Height, 20mm ID
Magnets:
16
N35
2mm thick
4mm wide
8mm long


What i did to make the hubmotor work:

Rewind the HDD Motor (See Specs)
Make a new magnet ring
New steel can
(I hope it can be seen why i just call it as a whole DIY motor- Really the only thing left from the motor is the stator- Otherwise everything else is completely different.)

There are still a few issues like spinup but when it gets spinning its a viscious force that i just cant wait to see hit something in the arena

When a email is sent to register are we expected to receive confirmation or something back? (Just making sure incase i sent it to a wrong email adress or something)

Haha yes! its 26 minutes away by bike

The event was awesome (as always!)

Thank you to everyone that organized the event and helped with it!

The filmcrew had a awesome setup and the stream looking back at it is VERY good and with alisha it brought alot of life and motivation to it
I do hope she had some breaks though since i always saw her up at the little upstairs platform thing and when Marien also came it was better as she wasnt alone anymore and the commentary was nice! I think Alisha and Marien make awesome commentators together

I heard that there was little people to take things apart again and im very sorry i couldnt help with it and rushed out quickly- Next time i'll try to help set things up and take things apart (if i manage to come alone as my mother wont be as enthusiastic about it )

Overall the event was just so good! loved every single second of it!
