Thread: Totally new -Needing advice

  1. Totally new -Needing advice

    OK, my niece called last week and asked for help on a science project where she had to build a car to go around obstacles. I started looking up websites and one thing led to another and I found that youtube bioloid humvee transformer and I really want one of those. That's just too cool.

    I think I can do it. I'm an electrical engineer and I've tinkered with fixing/modifying electronic games for years. How hard do you think it is to make one of those Humvees? Has anyone here made one or something similar? I'd hate spend $1000 on a Bioloid comprehensive kit and the extras just to find out I bit off more than I can chew. Are there any cheaper kits that can do the same thing? Any out of the box humanoid robots that can bend over and roll? I'm so new to this it's embarrassing to ask questions.

    Any help/insights you can provide will be greatly appreciated.

    Regards,
    Linda

    Hey Linda, welcome

    The bioloid kit is the only kit that I can am aware of that has the ability to fold onto itself like you would need. There are other kits such as the Robonova that can bend over and roll, but I don't think it would be possible to mod one out to a hummer transformer. It's definitely an ambitious project, but if you are able to finish it, be sure to enter it in the contest. I'm sure everyone here will help you out a lot on it!

    Hello,

    I think that it is a good project, that would be good to do with a Bioloid Kit. However, if you are good with Autocad, you could probably make it cheaper by getting the parts CNC out of aircraft Aluminum and buying the servos and a servo controller. I all comes down to how much money you want to spend to get the end result that you want.

    I'm not so much worried about the cost as long as I'm happy with the result. I do care about my time though. I'm spread a bit thin already. I would have loved to buy that Humvee transformer from the owner and just made small tweaks and modifications to it. Anyone one want to make one for a small fee plus materials? It may come to that after I start playing around with this stuff. I hope not, this sounds like fun project.

    Regards,
    Linda

    If you're an electrical engineer you've probably got a bit of an iron thumb anyway, meaning that you're probably ahead of your average joe as far as building things or putting things together. The Bioloid kits are basically, a robotic lego (or erector) set. All the pieces are modular, they're meant to attach together very easily... really it shouldn't be an issue for you to build something similar to the humvee. It might take a month or so (less if you have solid blocks of hours to get things done, I wish I did haha) to get it built and learn their sequencing program, but I don't think it's out of reach for any engineer by any means, let alone average hobbyist.

    Agreed, tres cool. I would think some of the better humanoid frames could be modified without losing sanity. Definitely be a bit of work getting it all packed in properly.
    An accomplishment worthy of praise, and a secure straightjacket. (In that order.)

    Q - How long did it take?

    A -Thank you for interest in my robot. How long? Um... Actually, I used up all of my summer vacation but it was worth consuming.

    I love this robot too, I have the second comment on this video : )

    Um... Just to clarify... You did not make the hummer transformer robot, right? Your post is kind of confusing.

    I want to address this bit first:

    Never be embarrassed to ask questions. We all have to start somewhere.

    I've never seen another project like this, but I don't think it would be too tough. I think the hardest part might be finding the right toy truck to hack apart.

    If you can wield a screwdriver, you should have no problem. I built the Bioloid humanoid in about 7 hours. Programming is pretty easy, too. Servo positions are set using a pose-and-capture system. You can move some servos, capture the positions, then lock those servos while you move others around, and finally fine-tune the positions through the software interface. The behavior programs are laid out using a graphical interface, kind of like a branching flowchart.

    Not that I'm aware of. Bioloid is the best for this for a couple of reasons. First, the same actuators can be used as servos and as continuous-turn motors. This is convenient because it allows you to use the same brackets to mount both servos and motors. Another thing that helped make this transforming design possible is the wide rotation range (300 degrees) of the servos.

    Oops! I though I made it clear.

    I did NOT make the robot... Whish I did though!
