CORRECTION: The proper way to calculate the gear reduction is to use the effective diameters of the drums (outer drum diameter - rope diameter)

"Gears are sooo third century BC. Its time for something different"
Starts using ropes which is being used since caveman times

What is this, a scientific testing approach for an actuator, a solid testing phase, a good explanation of physics, and freely available files? You have earned yourself an instant subscriber, that was top notch!

Just a tip from a hiker who has been using Dyneema for years. If you want your rope to last longer, don't let the rope contact itself. In the video it looked to be touching where it was wrapped around. Dyneema is very strong, but if it is rubbing against itself it will get damaged. I learned this from putting a Dyneema tent into a Dyneema stuff sack. Cool video! Also, the Your Mama joke took me by surprise and cracked me up. :)

18:45 Reminds me of a kid waking up a parent at 5am.

I love the cool confidence of it drawing shapes wrong.

The drive is brilliant. Your capacities as a designer and engineer are obviously evolving, but most impressive is your capacity to explain things clearly.

I laughed out loud during the first jumping part.  It just looks so much like a little creature that is inexplicably frustrated with the ground and trying it's hardest to beat it up

I am an Electrical Engineer and seeing a simple exponential, explains things so well, despite knowing nothing of mechanics.
keep up the good content

🤪the inserted "yo mama" joke... priceless!

Can’t believe it’s taken the algorithm this long to show me this channel.

0:16 ah yes. Rope. The most modern of inventions 🤣

As a sailor, I can tell you that we use this drive system literally everywhere on a sailboat, even steering

As a sailor, I saw you messing with bent steel wire and paracord and was like "noooo!" but then you found what I believe is the right answer, and I was "yesss!", not because I agree, but because it says a lot about your process, and that I will learn from your other work.  Subbed, and cheers!

I appreciate the willingness to test until it breaks and showing that purposefully. Many creators often depict breakage as accidental and not necessary to the process.

How am I just now finding this channel? This is gold.

As an electrical/control engineer, I always regretted not getting an ME degree or minor.  Mechatronics was not a "thing" in the 80's.  I recently retired after 40 years of control engineering and have been working on my ME skillset with help from YouTube folks like yourself.  I've been screen saving your math and walking through it.  Keep up the great work!

Dyneema is a crazy material to work with. It’s absurdly strong, absurdly low stretch, absurdly light weight, and freakishly low friction. Not sure if you ran into any issues with its low friction, but it can be weird in how different to other ropes it is, because in some situations well known knots don’t behave as expected because of its lack of friction, something to keep an eye out for if you use it more.
Also it doesn’t like fusing to itself when you melt it, annoying for trying to keep the ends from fraying. Super glue works though if you ever need that knowledge.
