  • Who Likes Robots?

    Ok, this is a different blog post than some of the others on my HETTY blog, in that it’s robot themed.

    I have had a strong interest in robotics since I’ve been a kid, and I never outgrew it. However, I never formally studied Robotic engineering, only studied for a measly associates degree in Computer Information Systems. What robots I have made are from buying kits and sets, reading books about robots or watching videos on social media. I also have limited programming ability, but I tried to work around that. So either limited preset instructions, or using a remote control..

    I finished about 8 designs that can be qualified as true robots, in that they can be programmed, and they have sensors. Sometimes it’s only one or two sensors, but that’s enough for most purposes. Other designs are really just robot like machines with interesting engineering or science behind them, but cant be programmed or controlled. Just an on and off switch, or a light activated solar cell.

    Most of these designs are mostly plastic, and on the cheaper side. The most expensive set I did buy was 500$, the LEGO Mindstorms EV1 set. Considering that there’s more deluxe robots with multiple motors and processors with costs that are at least 10,000$, I think robots in the 30$ to 500$ range is a bargain.

    So here’s photos of my designs. Very limited utility, limited battery life, and not very durable. But all of the robots or machines on this blog post could move, and some can be programmed or controlled. Videos of the design demos can be found on social media apps like Facebook, TikTok, and YouTube.

    This last one is perhaps the best designed one I made, in that it’s has a more simple design, and yet it could move on different types of terrain. A whegged robot that moved 6 actuators on only 2 motors.

    So should I keep up with my hobby, or are these designs not that impressive?

  • The Plastic Waste Problem Could Be Solved (If You Want It)

    The Plastic Waste Problem Could Be Solved (If You Want It)

    I have environmentalist leanings. Not fully, but I make changes when I can, with an awareness that I’m part of the problem too. One of the concerns I have is with plastics. Yes, it’s useful, versatile, and convenient. But discarding it has created a massive environmental problem.

    Recycling plastic waste is more expensive and complex than originally promised, with limited capacity. While some plastic types can be recycled, others can’t. Many plastics are simply burned or end up in landfills or in various parts of the world. It can be bleak to think about, since plastic waste often take decades to decompose, and micro plastics exposure can lead to various health problems over time. Burning plastic contributes to air pollution.

    However, some online articles I read in recent years and days give me hope that plastic waste can be reused and processed. It turns out that plastic waste can be converted into a building material, like bricks, tiling, panels, and other construction materials.

    The first article I read was of a construction startup called Takataka Plastics. Two engineers found a way to convert PET type of plastic into tiles, and later lawn chairs, plant pots, coasters, medical visors, and other useful products.

    The second article I read was last month. where a team of Japanese scientists developed a “supramolecular” plastic that decomposes in seawater in 2 or 3 hours, leaving behind non-toxic by-products. These byproducts are then consumed by bacteria in seawater, leaving no pollution. There’s no microplastic problem with these newly developed plastics.

    The 3rd innovation I read of was just last week. Various companies in the Philippines are turning plastic waste into construction materials for homes and other useful structures. There’s various methods developed, but the most promising method is using high energy radiation to strengthen and process plastic to create stronger chemical bonds. This reduces the costs of building materials, reduces plastic waste, and creates new jobs and housing.

    Along with the discovery in Japan that certain types of bacteria in seawater can consume PET plastics in seawater, which may lead to genetic modification of these bacteria and the digestive enzymes they create to speed up the decomposition of plastic pollution in the oceans.I really hope that these innovations are developed further, because they have the potential to solve many problems at once. Reduce plastic pollution, improve environmental and public health, create materials at a lower cost, and create new jobs in lower income communities and countries.

    Plastic Pollution could be solved by science and engineering, if there is a proper funding and enough people in various countries who want to make it so.

  • How to Survive Poverty

    How to Survive Poverty

    Surviving poverty can be incredibly challenging, but with practical strategies and support, it is possible to improve your situation. Here are some tips and advice to help navigate difficult financial times:

    1. **Create a Budget:** Track your income and expenses carefully to understand where your money goes. Prioritize essential needs like food, housing, and healthcare.

    2. **Seek Assistance Programs:** Look for government or community programs that offer food assistance, housing support, healthcare, and utility aid.

    3. **Build a Support Network:** Connect with friends, family, or local support groups who can offer emotional support, resources, or even job leads.

    4. **Focus on Education and Skills:** Take advantage of free or low-cost educational opportunities to improve your skills, which can open doors to better-paying jobs.

    5. **Find Additional Income Sources:** Consider part-time jobs, freelance work, or selling items you no longer need to supplement your income.

    6. **Manage Debt Wisely:** Avoid high-interest loans and seek financial counseling if debt becomes overwhelming.

    7. **Take Care of Your Health:** Maintain a healthy lifestyle as much as possible; physical and mental health is vital for resilience and productivity.

    8. **Plan for the Future:** Set small, achievable savings goals, even if it’s a tiny amount, to build a financial cushion over time.

    Remember, improving your situation can take time, but staying informed, proactive, and seeking help when needed can make a significant difference

  • Effective Social Programs

    Here’s an overview of key government programs that assist low-income individuals and families, both in the United States and internationally:

    –Special Note: Due to the US Federal Shutdown and cuts and/or defunding of certain government agencies, the functioning of some of these government programs may be more limited in 2025
