"I sent robot forgeries to a handwriting expert." Video sent to me by a friend with the comment: "Ignore the clickbait headline. This guy designs and builds a system to hand write thank you cards. His machine learning travails are classic."

4.7 million views, so you might have already seen this one, but in case you haven't, here you go. I know, I'm known as the guy who posts videos of some researcher talking in monotone with 100 views or whatever, but on occasion I actually post something popular, but you might have already seen it, because, you know, popular.

Some highlights:

"What we're going to do is have my wife see if she can pick out the imposter from a lineup of genuine handwriting."

"Why is it so obviously fake?" "Every letter looks the same. Every 's' is squished up on the bottom. It's totally straight across. It just looks like a font.'"

"I'm going to sit down and write every combination of two letters." "If you're wondering if this is more work than just writing out the cards, we don't talk about that around here."

"You can't get to the moon by climbing successively taller trees. No, we need to stick the monkey in a rocket."

"Of course there's an open source repository that does exactly what I want, except written 10,000 times better. It even has a web demo. You gotta be kidding me."

"If I put this little tiny hand on the robot, I'm now technically correct when I say these are handwritten, which is the best kind of correct."

"Ron is retired so don't send him your handwriting samples. You're just going to make a bunch of work for him and make him hate me."

"I basically have my dream job building stuff of dubious utility."

This Micro-Mouse competition, where a robot mouse solves a maze, has been going on since 1977, and somehow, I never heard about it until today. The mice are not allowed to use any radio communication and have to do all the sensing and computation on the robot mouse.

The first phase of the competition involved finding the best algorithm to solve the maze. The best algorithm isn't depth-first-search or breadth-first-search, it's a flood-fill algorithm that optimizes the mouse movement such that it can find a path to the goal with approximately little movement, and end up, after exploring the maze both to and from the goal, knowing it found the shortest path. Actually a next step after that was finding the fastest path, which isn't necessarily the shortest path -- because the robot has to slow down to turn.

At this point, people thought the competition had been solved, but that wasn't so. In the next phase of the competition, people came up with ways of running the maze faster assuming all the competitors could figure out the optimal solution. The first was cutting diagonals. In fact algorithms were invented to optimize all turns, so the robot never makes square turns, even when there are no diagonals.

After that, people figured out way to improve the physical part of the robot: more powerful DC motors, gyroscopes to improve the robot's sense of where it is, and people carrying tape to get dust off the wheels. Because every bit of friction, or lack thereof, affects how fast the mouse can run. But even after all that, there was still one kicker yet to come: suction. People added a vacuum fan made from an inexpensive drone propeller. This holds the mouse to the maze and allows it to go much faster without flying off the maze surface on the turns.

Artificial skin with 3 senses: touch (force), temperature, and humidity. Works by combining a thin film material that changes shape in response to force, temperature, or humidity with a piezoelectric material that senses the change in shape and turns it into an electric current.

There's 2,000 sensors per square millimeter, with a hydrogel which changes shape in response to force and temperature, and because of its ability to absorb water, it changes shape with humidity as well, surrounded by a shell of piezoelectric zinc oxide.

This is created using a process called chemical vapor deposition (CVD). She (Anna Maria Coclite) is a CVD expert, but she doesn't talk about the details much in this talk. CVD is used primarily in the semiconductor industry. The main idea is to vaporize a chemical to deposit a thin -- 1-atom thick, or 1-molecule thick -- layer on a solid surface. A vacuum is created to vaporize the chemical. And chemicals are chosen so there is a chemical reaction on the surface. Without this chemical reaction, the process is called "physical vapor deposition" instead of "chemical vapor deposition".

She jump straight to talking about applications of the technology. My first thought was this could be used for robots, and she mentioned that, but what she thought would be the primary applications were medical applications, such as artificial skin for burn victims, and sense of touch for people with prosthetics.

"China's global lead extends to 37 out of 44 technologies that the Australian Strategic Policy Institute (ASPI) is now tracking, covering a range of crucial technology fields spanning defence, space, robotics, energy, the environment, biotechnology, artificial intelligence (AI), advanced materials and key quantum technology areas. The Critical Technology Tracker shows that, for some technologies, all of the world's top 10 leading research institutions are based in China and are collectively generating nine times more high-impact research papers than the second-ranked country (most often the US). Notably, the Chinese Academy of Sciences ranks highly (and often first or second) across many of the 44 technologies included in the Critical Technology Tracker. We also see China's efforts being bolstered through talent and knowledge import: one-fifth of its high-impact papers are being authored by researchers with postgraduate training in a Five-Eyes country. China's lead is the product of deliberate design and long-term policy planning, as repeatedly outlined by Xi Jinping and his predecessors."

"A key area in which China excels is defence and space-related technologies. China's strides in nuclear-capable hypersonic missiles reportedly took US intelligence by surprise in August 2021."

"Over the past five years, China generated 48.49% of the world's high-impact research papers into advanced aircraft engines, including hypersonics, and it hosts seven of the world's top 10 research institutions in this topic area."

"China has built the foundations to position itself as the world's leading science and technology superpower, by establishing a sometimes stunning lead in high-impact research across the majority of critical and emerging technology domains."

"The US comes second in the majority of the 44 technologies examined in the Critical Technology Tracker. The US currently leads in areas such as high performance computing, quantum computing and vaccines. Our dataset reveals that there's a large gap between China and the US, as the leading two countries, and everyone else. The data then indicates a small, second-tier group of countries led by India and the UK: other countries that regularly appear in this group -- in many technological fields -- include South Korea, Germany, Australia, Italy, and less often, Japan."

You can compare any technologies between countries. The technologies are categorized into "Sensing, timing and navigation", "Transportation, robotics and space", "Artificial intelligence, computing and communications", "Energy and environment", "Advanced materials & manufacturing", "Biotechnology, gene technologies and vaccines", and "Quantum".

In the "Sensing, timing and navigation" category, they have "Photonic sensors".

In the "Transportation, robotics and space" category, they have "Photonic sensors", "Space launch systems", "Small satellites", "Drones, swarming and collaborative robots", "Autonomous systems operation technology", "Advanced robotics", and "Advanced aircraft engines".

In the "Artificial intelligence, computing and communications" category, they have "Artificial intelligence algorithms and hardware accelerators", "Advanced data analytics", "Advanced radiofrequency communications", "Advanced optical communications", "Advanced integrated circuit design and fabrication", "Highest institution rank for United States", "High performance computing", "Protective cyber security technologies", "Distributed ledgers", "Natural language processing", and "Machine learning".

In the "Energy and environment" category, they have "Supercapacitors", "Nuclear waste management and recycling", "Nuclear energy", "Photovoltaics", "Hydrogen and ammonia for power", "Directed energy technologies", "Biofuels", and "Electric batteries".

In the "Advanced materials & manufacturing" category, they have "Smart materials", "Novel metamaterials", "Highest country rank for United States", "Highest institution rank for United States", "Nanoscale materials and manufacturing", "Critical minerals extraction and processing", "Advanced magnets and superconductors", "High-specification machining processes", "Advanced explosives and energetic materials", "Coatings", "Continuous flow chemical synthesis", "Advanced protection", "Advanced composite materials", and "Additive manufacturing".

In the "Biotechnology, gene technologies and vaccines", category, they have "Vaccines and medical countermeasures", "Synthetic biology", "Highest country rank for United States", "Highest institution rank for United States", and "Biological manufacturing".

In the "Quantum" category, they have "Quantum sensors", "Post-quantum cryptography", "Quantum communications", and "Quantum computing".

When you do a comparison, there are 3 tabs, "Flow of human talent", "Research Contribution", and "Insights".

In the "Flow of human talent" section, it shows the flow of people between countries as they go from "Undergraduate", to "Postgraduate" to "Employment".

In "Research Contribution", it shows rankings in the category you chose ranked as "Countries ranked by highest H-index" and "Proportion of publications in top 10%".

The insights tab has their own commentary.

"Singapore performs very well, attracting researchers particularly from India and China to its two field-leading universities, the National University of Singapore and the Nanyang Technological University. The research that emerges from these Singaporean institutions places Singapore as one of the top countries in AI algorithms and hardware accelerators."

One-Wheel Cubli Balances Like Magic


Eight years and 14 million views ago, ETH Zurich introduced the Cubli, a robotic cube that can dynamically balance on a single point. It’s magical to watch, but at the same time, fairly straightforward to understand: there are three reaction wheels within the Cubli, one for each axis. And in a vivid demonstration of Newton’s third law, spinning up a reaction wheel exerts a force on the cube in the opposite direction, resulting in precision control over roll, pitch and yaw that allows the Cubli to balance itself, move around, and even jump.

"LEGO is discontinuing MINDSTORMS in 2022." Before I had a chance to play with it. End of an era? Now we have Arduino and Raspberry Pi and lots of other single board computers and products aimed at teaching kids programming and building robots.

"While this is apparently the end of LEGO MINDSTORMS, though, the LEGO Group isn't abandoning the concept altogether. 'We still have strong belief in the Build & Code proposition and will continue to support it through platforms such as SPIKE Prime, and we are continuing to hold on to the trademark for the MINDSTORMS brand and assessing our future plans together with LEGO Education."

Tentacles gripper. Soft pneumatic rubber tentacles that get all tangled around themselves and the object being gripped. Requires no sensors or complex algorithms.

You gotta love the way they hint at the end about the possible application to warehouses. Gripping objects is one of the few reasons there's still any humans in Amazon warehouses.
