    Lénárd Pásztor with four motors?

    Jesse Yeah, exactly. I'm working on a Lego Battlebot that uses these wheels and was hoping to be able to figure out how to either use Sbrick's software, or Brickcontroller 2 to use a video game controller instead of a phone screen.

I'm working on a Lego Battlebot that uses these wheels and was hoping to be able to figure out how to either use Sbrick's software, or Brickcontroller 2 to use a video game controller instead of a phone screen. Then I could create a profile that lets me mix motor movement in a way that the two joysticks control the bot like a first person shooter (fwd, back, rotate, strafe side to side etc.) Been using power functions for a while, but brand new to Sbrick and trying to replace the IR controllers with something with more control options.  less

    Lénárd Pásztor Do you have ideas how do you want to control these motors?

    Jesse I was planning on getting a bluetooth video game controller of some kind. I've read in forums that PS4 and above controllers tend to work, but also equivalent aftermarket ones that are cheaper.

I've read in forums that PS4 and above controllers tend to work, but also equivalent aftermarket ones that are cheaper. I saw this video and was thinking of looking for this controller: https://www.youtube.com/watch?v=irMby1yHxYs&list=PLzR2ftjB03Fn5czSsDPul1maicM3hgmdI&index=8&t=77s . Then as far as controlling movement, I would want it to be a 2 stick control... probably left stick is forward, back, strafe left/right... right stick is rotate left/right... and I'm not sure what up/don would be (usually that would be more precise aiming in a shooter, haha).  less

    Lénárd Pásztor it is a very custom useage of the motors. The current SBrick app can't do this way, because the two stick controlling all of the four motors in parallel. We take a look about what can we do, because this model can be fun

    Lénárd Pásztor is seen a car with gears like this, but can't remember for it's name. It was not lego. Can you help with a link? it would be great if I can see it while it is moving.

    Jesse Sure, this video details how a guy programmed a control interface on his phone to move this kind of vehicle...here's a link to the section where he shows it moving: https://youtu.be/SYtFCyF44h0?t=533.

I actually think I may have figured it out tonight. I bought a PS4 controller and connected it to the app BrickController2 on my iPhone. Then I was able to specify what motors spin a specific direction for each joystick axis and created the correct combinations to move the way I want. Here's a diagram of the way you cans each motor needs to turn to create movement in each direction. https://www.vexforum.com/uploads/default/original/2X/c/c7963dec531b7e893ddcf91c4fc9159928c4b56c.jpeg
    I'll try and get some video showing the movement and how the controller controls it and once I'm really happy with it I can screenshot the settings in case other people want to do it.  less

    Jesse This video also explains the movement really well: https://www.youtube.com/watch?v=YJaX3vQ6kHw

    Jesse Here's a video showing the bot I made in action. It's being controlled by a PS4 controller through my iPhone running Brickcontroller2... and standard PF motors plugged into an sBrick receiver. https://www.youtube.com/watch?v=_VUzNrJ3X-w

    Lénárd Pásztor checking it! Forwarded to the dev team, I waiting for an answer.

    Salvador Otero Alonso Here you have an example of the use of these wheels and some code in typescript and Python that dev team can look at to take an idea http://www.yahboom.net/study/Omni:bit the wheels can be bought to them, in Aliexpress ... etc
