Just some motors working overtime

that comes straight outta (into) "System Shock"

I totally agree, probably the greatest part.

They absolutely do not do that Steppers operate in steps and so the pitch of the noise says literally nothing about torque, effort or even power, only speed, and even that is more nuanced. Basically you couldnt be more wrong for this specific type of motor.

stick an ammeter on them, and the tiny but spaced pulses do in fact use more energy! @@BeefIngot

@@BeefIngot I am making a point that the noise makes it apparent for the end effector motions when the non linear angle change is very large. Your definition of effort is not my definition of effort, i am talking from a control perspective. Also, P = t*w. Even in your definition, i am not as dramatically off as you think

@@Apocobat Even with your attempt to pretend you meant something different you are still very wrong. Stepper motor torque is non linear and decreases as speed increases past a small plateau at the start of motion. Basically they are good up to around 200 rpm usually but faster than that the torque drops off a cliff. The pitch tells you nothing about what their torque or work output is at any point outside of if you hear missed steps. More than that, to class speed as effort I think isnt really a great idea because for steppers and their typical applications its usually much kore relevant to talk about their fastest reasonable acceleration in any given application and how well they maintain torque across the range of speed they have. Furthermore you didmt even get the formula for power correctly. Its work divided by time. Basically, Im not letting you get away with this "but I actually mean something totally different than what I said". I totally know that this doesnt really matter but your initial comment had this annoying popular science, lets not care about facts, toxic positivity type of vibe that generally annoys me. Its ok for something tl be cool but also have downsides. Its annoying when people act like everyone should only say "positive" things because its a useless and backwards mentality. Some sioent steppers or foc controllled brushless motors would indeed be cool improvements, though for a proof of concept whatever he has on hand is the best tool for the job because fail fast. So there is a lot of nuance.

@@Apocobat lmfao. Bro did you really just pretend you meant to abbreviate rotation speed with w and force with t? You really saying you expect anyone to think that you misaligning the most basic P=W/T actually meant something completely different than what you typed? Its so obvious you're bending over backwards to try to retroactively make yourself sound right 🤣🤣 The funny thing is, even with your change here, it still wouldn't make any sense. The motors aren't giving any more effort because stepper motors dont use power the way you think they do. These arent like traditional BLDCs. They are given an amount of power per step or microstep regardless of how much of that they use, so literally, in this one case, that formula is meaningless, because you are using the same wattage no matter if its moving or standing still. In fact, the way most stepper drivers work, is that you configure a max current to run through them, and that's it. That current stays damn near consistent no matter the speed. I'm sure now you'll say you just meant like what is happening from the reference frame of the plastic and not the power of the motor though. Keep changing it up my man.

Damn bro how did you spot that 😂

Is it not a reflection of something in the monitor?

If you had a simple drill on a motor controlled slide, you could drill holes into an object at many different angles, if substitute a milling cutter and you have a very flexible 3D CNC machine

Yes what is it for. ??? why build this for what, to do that

​@@chriswilkinson2548why not? You have the knowledge and the tools...

i think its clear by the shape of the attachmenrt what he intemded to use it for

@@WithExtraChicken I would NEVER....get caught using it.

Oh that’s what it is. I thought it was balancing a dild0

Yea what he said🫠

I saw that too. Haha.

Yes please!!!

Parts of the audio sound like Tool song

thats brilliant! it's likely because at that part of the demo the mechanism gets stuck and its drawing overcurrent. That jerky part doesn't look intentional, probably is a fail, but still cool demo. lol

looks like their hands reflecting in the monitor, there is somthing similar at the start of the video and its just before they get up to move the camera.

yes ir is just the reflection of a hand

Cool showcase but i struggle to find an application where this is better than a 2-axis approach, which is much more rigid and proven.

⁠@@RCP-1136 I could see an application where this is used as the end effector of some bigger system where you then won’t attach a drill motor to it but use its rotation alone as the rotation for the drilling (for example). Then you could also position the drill in positions non-collinear to the direction of the larger system (maybe some tiny medical devices that are long and fill out the whole available space and are thus not able to point their tip in the direction they want to drill in

A possible application of this mechanism is a medical robot that performs operations using laparoscopy. Imagine that the focal point of this mechanism is a puncture in the abdominal cavity through which instruments are inserted and incisions are made within the patient. (Sorry for automatic translation) :))

well i want this as my 3d printer bed

I wonder if it could gold pan….. 😀

@@BonesFPV our minds work alike fpv for life!

Holding props in movies that need some weird movements to be green screened out later is a great application for robots like this...assuming you wanted to be practical.

By the way, it was not in an emotional manner, but was about how elegant and aesthetically it satisfies the expectations from a platform manipulator.

What's the mechanical equivalent of "there once was a man from Nantucket..."?

nice it will make a good floor mop

Although making the device more complex will also increase the chances of failure. So there is an option to simply move the entire structure from the roller with an additional powerful drive vertically

Would be great for filming, among other things...
