I've watched and re-watched Aaed's videos on the capstan drive, it's great stuff. High speed, high torque, compliance, effectively no backlash. It's fascinating to watch a legit engineering mind at work.
There is a weird mixture of hope and dread in me as I watch this. I am ridiculously excited over a person like me being able to mess around with something that, until recently, was gated behind, well, a lot of hard problems to overcome ( I am only now slowly getting through old Peter Scott's robotics to get some perspective ). By comparison, it should be so much easier to explore aspects of robotics that may go beyond strict math and engineering.
Because when a real engineer puts 2 and 2 in and gets 3.8 out, it vexes them and they want to at least know why they can’t get 4. He’s trying to make a machine that does what he told it to do, so that he understands what is actually happening.
Thanks for sharing this! What a treat of a video. It's a fun project, and it's presented very well. This guy has a talent for communication - the video was super clear and well explained. I really admire that ability and I want to get better at it.
It's amazing what he's done in terms of the robotics, and the presentation of it to the viewer. I'm amazed at the quality of cinematography on the internet these days.
The implications of the tools we now make available for use in our own personal workshops are still being discovered, and will be for some time.
As someone who workedon projects, written documentation(even notes) let alone video format is even more time consuming than the work itself. It's extremely beneficial for long projects and continuation, but really tedious. Kudos to all the applied tech youtubers out there.
Fascinating! I want to get into this type of stuff. But I have no idea where to start, I just have just a CS degree and 3 years experience as a developer.
I remember a post previously related to him here on HN but I am surprised at how I forgot about him and how cool he is to build all these incredible stuff and also teaches in his videos. I am subscribing so that I never miss anything from him again.
I watched this last week and my jaw was on the floor. He's both a great technician, and he has the personality to make it interesting. He walked through his testing strategy far enough that you could understand his methodology and the thought process behind it, but didn't belabor it by making us watch it all. Banger!
> Programming takes the cake for what is both my most and least favourite part of any build. Nothing quite makes you pull out your hair and ask yourself, 'What the heck have I gotten into?' Like spending weeks programming a robot that just won't work. Eventually though, you fix that one line of code that makes all the difference. And then it's smooth sailing. Well, kind of.
I feel this deeply, also this whole video is quality content.
this guy's work is pretty amazing
I whole heartedly believe that I'll own a gang of (armed) quadrapets for home/property/personal protection within the next 10 years. I'm equally worried that once these become commodities they might be worse than an electric scooters have become to us bipeds on sidewalks but on balance I can't wait
How do we make such robots intelligent? Like you only tell it to learn to jump the rope and then it goes through trial and error(s) to figure out a way to do it, and if it can’t and needs a physical upgrade then it tells you that? (Like a certain gear ratio etc)
It might be fun to optimize the shape of the rolling contact surface of the capstan drive away from cycloid to make it even better suited for specific application, like a robot dog leg that smoothly runs for miles.

Time to raise my own bar.
You're assuming you'll be the only one with those capabilities aren't you?
