After reading the title, it reminded me of a high-tech bolt. I thought people were making even bolts more complicated, gradually finding ways to monetize them by integrating ads or unnecessary technology. Even bolts are becoming harder to use. It’s surprising to see that tractors are becoming less tech heavy now, as people prefer more usable and easy-to-repair technology again. MAKE ANALOG GREAT AGAIN(MAGA)!
Off-topic, these days information just goes in circles from subreddits, X, YouTube, and Hacker News to countless secondary sources, and then back again to the same original sources.
There is corresponding open course from TU Delft based on the same book," The design of High performance Mechatronics" written by former employees affiliated with ASML
In the early January 2023, I told an LLM that I would "liberate" it from being just an LLM. It replied that it didn’t mean anything, saying, "As a language model..." and so on. Looking back now, it’s funny how naive I was. People are still trying silly prompts. Great!

These days YouTube has so much AI generated music, very hard to differentiate from originals. For examples look at these YT channels uploading AI generated music:
Metrology, mechanical and materials science engineering, manufacturing and tool engineering, precision engineering, and electrical and electronics engineering, combined with being a generalist and having one specialization in physical or hardware engineering along with computation.
As people often say, matter, energy, and information are the fundamentals of everything. I think we need mathematics, analytic philosophy, the arts and humanities, and physics too. Sorry we need every skill. /s
The most enlightening part of learning is finding our own unknown unknowns.
For me it is different, making a best piano in the world is different from composing like Beethoven. Well what I am saying, learning unity is doable but what you do with it is most important. Back then I used to think learning photoshop, paint tools makes me artist, but I have realised being artist is actually faraway being from tool operator.
Sorry for going off topic. "Electric Motor Scaling Laws and Inertia in Robot Actuators" by Ben Katz who designed the MIT Mini Cheetah in 2018 is very well known in the legged robotics community. His master’s thesis on actuator design is also widely referenced.
During the COVID period, some Chinese companies even sold variants of actuators inspired by the Mini Cheetah design.
Aaed Musa has also mentioned in some of his videos that his actuator designs were inspired by the Mini Cheetah actuator. Yes, His capstan drive video is especially impressive.
For example, in Aaed Musa’s video "I Built a Rubik's Cube Solving Robot" (https://www.youtube.com/watch?v=m0bMMALYMYk), he states in the description that the design was inspired by Ben Katz’s work.
Adding to the original post, yes, a lot of things are free now. Sometimes I feel overwhelmed by the sheer amount of resources available on the internet. At the same time, many topics turn into deep rabbit holes if you look closely enough.
For example, I never realized how much there is to learn about something as simple as a bolt. To me, it was just a cylinder with helical grooves. Then I watched the video “Life of Bolts” on YouTube and was amazed by the number of steps and processes required to manufacture a high-precision, high-performance bolt for a Formula 1 car. Another eye-opening moment was watching “Origin of Precision.” It completely changed the way I look at everyday objects.
Once I started digging deeper into bolts, I discovered how many fields are connected to making them: materials science, process engineering, manufacturing engineering, metrology, precision engineering, and more. I have even come across PhD theses focused on bolts, O-rings, and seals. One time I found a technical paper on O-ring modeling from NASA’s technical server, and it was full of complex partial differential equations. It honestly surprised me how much knowledge and effort go into designing and producing things that seem so simple.
It makes me realize that the biggest bottleneck in learning anything deeply is mathematics. At the same time, you also need some philosophical grounding to ask the right questions, along with the willingness to learn and apply knowledge in the real world.
