Designing and Fighting an Omnidirectional Combat Robot - Part 1

- For my first Beetleweight Combat Robot I tried a unusual side-strafing drivetrain known as 'Kiwi' or 'Killough Drive'. I then took it around the country to see what I could learn from it, now being relayed in HD Video!
Holy mother that eggbeater is indeed lethal. Mk II is going to be a MAJOR upgrade. Watch out beetleers!
underrated content right here
Yeah it’s high quality
Very interesting video. Thanks for sharing! Hearing v2 spin up its weapon: Now that's a weapon!
Fab video. I built a kiwi drive overhead saw as a beetle last year, and I'm currently redesigning it as a hammer saw. Couldn't agree with your points about the strengths and drawbacks of the drive system more. Let me know if you ever want to compare notes!
Great video 👌👍👍
Looks like a mini Ominous.
I think showing the drive motors looks fresh as hell! Aesthetics over function!
Love it! I feel I've learned a lot about omni-drive systems from this video.
Also, thanks again for letting me test drive Scale at Havoc 5. It means a lot, mate. 👍
Thank you for posting this video, excellent delivery.
Nice robot!
Sounds like an Air raid siren spinning up.
Awesome job, will be watching your build career progress ;)
_Drum Driftahhh!_
Great video! With so much weight in your budget, you might consider the daring option of a pivoting weapon mount to maintain the invertibility (think monsoon/lock-jaw). You could also use a servo self righter, but that’s nowhere near as cool!
From the thumbnail, I was hoping for a triangle robot with three big cylindrical rollers that just sort of slide around for omnidirectional movement. That wouldn't be very combat worthy, though ... too easy to push around.
This has been done, a very old Australian featherweight called 'Sidewinder' just used standard Bunnings red wheels in place of omnis. Worked ok apparently.
@@BrokenLinkRobotics Thanks for the info! Hmm ... I guess you could make a simple robot with three almost vertical corner motors.
Each motor is tilted a bit inward, with the shaft poking above and below the robot. The "wheels" are simply the rounded shaft tips.
Very few points of failure. No gears, obviously. No way for a bent armor belt to seize up the wheels. Might also be good for trying to save weight.
okay your latest version is scary
Please do a video on your ants!!!
To combat the gyroscopic effects from having one drum would it be possible to use two more that spinns in the other direction?
Yes, though that would add a fair bit of weight, complexity, and power consumption.
Thank you for posting this video! Documenting the progress is super helpful. Is there any chance you could bump up the sound of your mic for the next video? I seem to have to up the volume for your videos compared to others, and makes it a bit hard to hear what you're saying
will do
@@BrokenLinkRobotics Not OP, but just wanted to say thank you for these videos. For reference if it's worth anything, I've had to up the volume of my laptop from the usual 20 % to 40 % for both this and the spinner video. The balance between the clips seems normal.
These are awesome, will you do one for Split?
Plan to in time, possibly after the next one
show us how you assemble the gear motors for the omni wheels!
For v1 it's just a stock standard 25mm Chinese gearbox with a drone motor mounted to the standard back, but v2 has custom ones which will be covered in next video.
What FRC team were you in? If I had to guess, barker redbacks with how much you know.
FRC7561, now mentor for 5985.
what did you use to control the omni movement , a fpv drone fc ?
Mixing in the transmitter
Algorithm algorithm algorithm algorithm. Algorithm algorithm?
Algorithm!
@@BrokenLinkRobotics why didn't I think of that...
It's been done before, and they didn't work very well due to lack of traction.
FWIW you only need two wheels and a sled.
Your voice is too low, it's almost annoying
IDK it sounds very nice to me
