This project was created on 05/18/2022 and last updated a month ago.

Description

Who doesn't want to have a really big remote controlled toy?

It's a big baby of 25kg, with a full aluminum frame, a spring suspension system and 4 motors wheels.

The remote controller is here: https://hackaday.io/project/185425-universal-robot-remote

As proposed by email, i have subscribe this project to the Hack it back challenge: https://hackaday.io/project/186499-hack-it-back-rise-of-the-hoverboard

Components

  • 4 × Old Hoverboard (for the wheels & batteries) (you can find broken one for around 20 buck on ebay)

  • back on this !

    Tanguy • 03/20/2024 at 09:38 • 0 comments

    I've been busy for a long time, but now I'm back on this project!

    Here is the new frame (building 2 of them)

  • New "all in one" 3d printed part for the legs

    Tanguy • 04/13/2023 at 15:32 • 0 comments

    New "all in one" 3d printed part for the legs :



  • New metal parts! This time in stainless steel of 4mm.

    Tanguy • 04/07/2023 at 11:00 • 0 comments

    New metal parts! This time in stainless steel of 4mm.
    Hope it doesn't bend like the 5mm aluminium one.

    Thanks to John steel https://www.john-steel.com for the cutouts !



  • Silent bloc everywhere

    Tanguy • 04/06/2023 at 08:45 • 0 comments

    Given the results of the last test, I am trying to place shocs/vibrations absorber on each leg and on the electronics compartment

  • Aaaaaaand... Some parts bend.

    Tanguy • 02/17/2023 at 00:00 • 0 comments

    Look like 5mm aluminum wasn't enough..
    I am thinking about using 4mm Inox for the next version !

  • First test outside !

    Tanguy • 02/15/2023 at 11:24 • 0 comments

    (Sorry for the vidéo low quality)




  • bigger wheels !

    Tanguy • 01/30/2023 at 21:27 • 0 comments

    I have buy an hoverboard with bigger wheels, i am gonna search for a second one and put 4 of those big wheels on the robot.


  • RC control ! 4 motors, 10% power

    Tanguy • 10/14/2022 at 21:33 • 0 comments

    All the 4 motor are now wired, i use 10% power for testing. This thing is waaaay too powerful, need to take it outside.

How do you get the wheel-speed?There is no encoder. The puls-output is not enough, I think.

And the direction of the wheels are not detected.

  Are you sure? yes | no

Tanguy wrote 10/08/2024 at 10:52 • point

The wheel has a built-in Hall sensor, which provides decent speed feedback !

The main challenge is finding an affordable electronics board that can properly control the motors (and handle the feedback). The controllers I’m currently using are very cheap.. But I’m exploring the possibility of using the original hoverboard PCBs itself. There is some custom firmwares for it, by flashing the STM32 (like this one https://github.com/lucysrausch/hoverboard-firmware-hack/tree/master )

  Are you sure? yes | no

buniakesteban wrote 10/08/2024 at 18:07 • point

I was able to use the original PCBs that came with the hovers flashing this firmware: https://github.com/EFeru/hoverboard-firmware-hack-FOC

It works great, it's fairly easy to do, and the best is that it supports different operating modes for the wheels!

  Are you sure? yes | no

Great project! What's next now that you had some successful driving tests?

  Are you sure? yes | no

Tanguy wrote 04/24/2023 at 11:04 • point

Thank ! The driving tests was a success, but some aluminium part of the frame bend.
I am right now fixing this by replacing them by steel parts, and improving some 3d design.
Next step is adding some electronics (GPS, imu, camera, sensors, 4g modem) and some software to remote control it like a drone. ^^

  Are you sure? yes | no

man I really like this project I also have two hoverboards laying around and I was thinking of doing something with them and this project really helped me thanks bro I really want more updates keep making them come 

  Are you sure? yes | no

Tanguy wrote 08/07/2022 at 18:16 • point

Thanks ! I will continue to post project updates.
I hope to be able to do the first driving test soon.

  Are you sure? yes | no

ThanhTran wrote 06/03/2022 at 19:41 • point

Looks very intriguing.  Quite different between the first and second version. Please keep the update and pictures coming

  Are you sure? yes | no

Tanguy wrote 06/03/2022 at 19:51 • point

Thanks ! Yes I changed my mind for 2 reasons 1) The cost, lot of different metal parts is more expensive to buy than 8x the same parts 2) I was afraid of having a lot of mechanical backlash with all the joints, and not being able to put bearings everywhere.

  Are you sure? yes | no
