Lego Compatible Servo

Has anyone tried this before? I was hoping I could plug it into the boe-bot's P14 and 15 pins and do some fun activities with my class.

Thanks,
Diane

    Hello!
    Speaking for myself, not yet.

    Sometime last year I was working out the details to, ah, reproduce the basic BOE bot design using LEGO, both wheels, and a platform.

    But making the design work proved difficult.

    Erco, why are there two mountain lions examining your car?

    And why did a crowd of robots land on an island in Puget Sound?

    Well I just ordered two. They'll be here in days. When I get them to work with the BASIC Stamp2 on the BOE, or a Propeller 1 rig on a PAB, I'll report it here.

    And if it works, they'll also include first photos of the bot.

    Thanks for being the guinea pig!

    Interesting. I'm not convinced that that particular form factor is the most flexible for LEGO use. The guts appear to be a more-or-less standard 9 g CR servo. I'd rather see the dots & holes on the 4 or 5 big flat sides of the servo. You could roll your own by using those adhesive LEGO-compatible rubber strips. And of course the actual wheel choice and connection method would make or break the system.

    Another curious find on that site is a uC board that has LEGO-size holes on the PCB, along with "conductive Maker tape". There's a chance that may actually be more difficult than using plain old wires, but I do like the thinking. At a glance, it LOOKS modular. https://www.browndoggadgets.com/collections/new-crazy-circuits-chips/products/crazy-circuits-robotics-board

    A simple BoE-style breadboard is pretty flexible. Seems like a LEGO-based construction system with a modular breadboard system (done properly) could be successful.

    There's an Australian (maybe Kiwi) LEGO-compatible orange robot chassis called Edison which already has a sizeable educational following in schools. https://www.amazon.com/Contempo-Views-Edison-Robot-2-0/dp/B01HSFMK6G

    I use Edison robots in my 5th/6th grade class. It's a good intro product, but its limitations are frustrating. The kids really like it.

    Hello!
    Well both of mine arrived today, five days late as it happens. It turns out they resemble a pair of regular servos that I obtained from when RS was collapsing. [Think of the box of intended things to be used with the other platform that's also supported by the Shield Bot that's sometimes intended to enable the builder to try out ideas before committing to a final design on that platform.] @erco you suggested that they resembled 9g servos, well so are those.

    When the two arrived, I checked to see if they were a good fit for the wheels I had in mind. They were not. So these two are now being used, or will be used, for, ah, model management.

    Oh wow. Erco there's a soggy mountain lion looking through your garage for a towel.
