Lunaris

My progress and updates with my first-ever Spring flipper battlebot, Lunaris.

I will post every now and then when i have updates and progressions

Glad to post a update so soon on Lunaris already. The drive has been set up and works nicely. The wheels will be around a quarter less the size of the ones you see in the video when entirely finished.

Thank you for your information!
Seems to be an agile bot.

It is, using 1000rpm motors : ) I like having fast bots

I have managed to make the flipper work and now only the TPU parts remain to be finished Although the flipper is not strong and struggles to lift 630g in its current state it can selfright. Before the event i will look everywhere to buy actual springs instead of using 8 long rubber bands folded in half

Lunaris is pretty much ready for hannover just that i need to somehow make the servo a bit stronger so its able to wind the linkeage down better, Before i have just taken off the control circuitry of the servo and hooked up a esc to the motor and it worked very well but it came at the cost of my servos dying very strangely. they werent fully dead and still worked when they wanted to but very unreliably. i think maybe vibrations got the brushes bent but i am really unsure...

To go into more details on whats going on in it just because i have nothing better to do right now

I am using a 650mAh LiPo and it seems like i went a bit overboard because it can run like 15 minutes without a issue so i am set for a few fights or a long fun fight

Using a dual esc from amazon- basically the only ESC i could find that is for a brushed motor and at 3S they work pretty well but i do have some troubles turning after going in a straight line and have to let joystick go to the middle and then i can turn

If you ever make a spring flipper you should really do your research unlike me- i was thinking that a 13kg servo would be enough but thats far from the truth. You need a way torquier servo or geared motor for a spring flipper- Its my first ever flipper and didnt want to mess with Pneumatics or Hydraulics as i have 0 experience with those. Really hoping that it can atleast be able to lift a bot if anything-

(V2 will still not use those two or springs either but a diff experimental idea- i can make a seperate thread about it and documenting my experiments and results if anyone would like that, but that will be wayy in the future and hopefully allowed to be able to compete because i havent seen something like it before)

For the drive motors im using 12V 1000RPM geared motors because i like having a fast bot instead of a slow one- i dont know, faster bots really catch my eye and are more fun to drive imo.

I'm using a arduino to sense when its armed and hold that state till i flick a switch but the button decided to not work or maybe its the code so i will have to figure that out before hannover-

Sounds like swapping some battery capacity for a bigger servo might be an option here.

Anyway, one of those bots I really like to see happenin.

I could probably use a bigger... everything without a problem since lunaris doesnt weigh much

All my servos are dead so this means its no longer a flipper it'll just be a weird-looking (probably) ineffective wedge with extra steps- I tried so many things to get it to just flip properly again like before, didn't work and all servos decided to bail

I fear, that I could not participate next weekend in Hannover.

I have two Power-Servos for my two beetle-weight-bots. If you see a chance for repair of your bot, I could send it to you. (If interesst, please send me your adress asap)

Thank you so much for offering your servos- it means so much to me. where can i send my adress and more importantly how can i pay you back?

In the menue of the forum you see on the right side the field with the double -bubble? It is "Konversation". Please send me a PN (Destination ist "IBF".) Tomorrow I will bring the servos to DHL. (Time ist running...)

About paying... let's talk next week about. . I don't know the price and the source for delivering. If it is OK for you, you can order two new servos directly to me. Or you can send "my" servos after MMM back to me.

To your information: The servos did not used by myself. I tested only one servo about "functionallity". No mechanical load and no over-voltage. But the coverage is away.

I have done it (or so i think... still kinda new with the forum)

Thank you all so much im really speechless and really thankful- i was over here thinking i just wasted a lot of time into the flipper and programming and everything- it means so much to me i really did not expect you all to be this kind :,)
