If you’ve ever ridden a two-wheel bicycle, you know that you have to not only pedal to move forward, but also balance in order to stay upright while you move.


Two wheeler robots are difficult to make because they need to balance in addition to carry out commands. The balance is done autonomously, meaning that the robot must be programmed to figure out how to balance itself.


We’re going to skip this complicated step and instead use gravity to balance for us. While this makes the robot a lot smaller, it’s also a lot quicker and easier to build than the model in this image. Are you ready?

    You can also use bottle tops from water bottles.

    I do not have the wine bottle lids or cork. Is there something I can use instead?

  3. It’s up to you and your parents to decide what you do with the parts once you complete the project.

  8. Now I understand what you’re looking for! Okay here are a couple of websites that should have what you need:

    http://boyslife.org/about-scouts/merit-badge-resources/robotics/19264/robotics-resources/ (look near the bottom under “ARTICLES, BOOKS AND LINKS”)

    http://www.education.rec.ri.cmu.edu/roboticscurriculum/vex_online/safety/safety.html (this is directly from a company)

    Here’s a PDF with general safety guidelines: http://www.education.rec.ri.cmu.edu/roboticscurriculum/vex_online/safety/general_safety.pdf

    I am working with an NXT lego mindstorm robot.
    what will be the safety precautions that will fulfill the requirement 1 for the robotics merit badge

    thanks, 😀

  10. Hi Cristina,

    Thanks for writing! What sort of precautions about safety are you interested in? With building robots, since robot designs vary so much, there’s a lot of different safety measures that you can show the kids. For example, some robots are hydraulic, some use chemicals (like in a lead acid battery), while others have solar cells that you have to solder (which leads to a whole other area of safety). Let me know what you’re looking for so I can point you in the right direction. 🙂

    Happy experimenting,
    Aurora

    could you please describe the appropriate safety gear and clothing that should be used when working with robots?

    thanks 🙂

  12. The one you enjoy the most! 🙂 Really, it’s totally up to you. And if you decide to take them all apart, you know you can build it again, right?

    what is your favorite robot(s)?In other words which robots do you suggest I do not take apart when i’m done building them.

  14. Thanks

  15. Lots of hot glue for repairs! You can add skewers for offense.

  16. I am thinking about turning this robot into a fighting robot, any recommendations?

    Thanks. Kurt
