Robotic Arm What does a Robotic Arm Look Like? Gears End Effectors Anything Metal Not really: Since Robotic Arm is invented by Humans, we get to decide its function and look. Biomimicry: Before this project, I’ve started to think about biomimicry—how nature’s mechanisms can inspire robotic systems. In biological organisms, movement is rarely rigid or purely mechanical. Muscles, tendons, and joints interact fluidly to adapt to the environment with precision and efficiency. Biomimetic principl ...

Ronaldo’s Quote "I said this one year and a half ago and I will continue to say it: the problem is not the coaches. "I always give this example, it is like the aquarium. If you have the fish inside and he is sick, and you take him out and fix the problem. If you put him in the aquarium they will be sick again. “The problem of Manchester United is not only the coach. It is much more than that.” The Second Red Horror Last season (2024–25), we almost got relegated. Fifteenth. Out of ...

PNP The first unit of the Technology Seminar class asked us to collaborate and create a nameplate for the admissions team. Though I don’t have everything recorded, I still want to share some of my approaches and progress. Background Before this project, I already had some experience in CAD — I made my own PC case. It was my first big CAD project and took about a month… and it was painful. Here’s a little gallery walk: Looks cool, right? But it only looks cool. I didn’t leave enough margin f ...

My Pressure I always laugh when I saw this meme that our forefathers fought in the great war to save humanity and us from evil dictators, yet after their death they came to realize that the Gen Z now have depressions or pressures. It is a joke to them and to me. I thought, only those who experienced great trauma or great misfortune have the right to claim such honor. Others, are losers. A loser that is a failure in society. Nobody cares. Unfortunately, thoughts can be a crime. And I was sentence ...

Phones Can’t Trap Us A gun doesn’t become notorious because it is made out of metal. A gun is just a commodity that is man-made. Nicolas Cage is not the War of the lords if there are no wars. Simply, selling weapons create such conditions for war. Drugs did no became a problem until laws permit it. Should we then ban democracy if it is such system that allows drugs to be legal? So recently when I was traveling around the globe. I often see banners,PSA, or healthcare ads warning us to not g ...

Short Story I was customizing air filter panels. Why? Because I’m being irrational with my money. Just kidding. I was messaging a Chinese factory that specialized in producing paneled air filters.

I only need one.Manufacturer: Wait, let me check with my supervisor...Manufacturer: Our starting price is sixty, but we ca ...

Can Freedom and Coercion be Mutually Inclusive? When the little man asks for a job: But his acquaintance knits his brow and says that that is objectively impossible. Business is bad, he says, and he’s even been obliged to let many employees go. The man should not be angry with him, for it is not within his power, his freedom doesn’t extend that far. Who is the little man? The ordinary, powerless individual in society. Someone who believes the “propagandaish” promise of freedom, but continually ...

The Sorrows of the Tea The Sorrows of the Tea Upon arrival at the town, I was greeted by its name. The air, though transparent with the yellow mist of the sun, blossomed with a soothing smell of green tea. Though the sun hasn’t completely risen beyond the crest of the valley, it spilled a spoon of light over the rooftops as if they are the scales of the golden dragon. Yet, I was interrupted by the flashy red pictures on the walls. Mr. Weng and his son came out and greeted me. Mr. Weng was a dec ...

The day that I was 2,000 miles away from home I got a severe cold the day I was 2,000 miles away from home. That day, I finally went back to my grandpa’s house, two thousand miles east, saying goodbye to my twenty-year-old home. The Siberian wind bit my fingers and stabbed needles on the back of my neck.
