Comment on Every single Onewheel is being recalled after four deaths

magnetosphere@kbin.social ⁨1⁩ ⁨year⁩ ago

…a firmware update that will add a new warning “Haptic Buzz” feedback that riders can feel and hear when the vehicle enters an error state, is low on battery, or is nearing its limits and needs to slow down.

Instead of relying on a “Haptic Buzz” that the rider can choose to ignore, maybe the board should just automatically stop/slow down under these conditions. If engineers insist on the “buzz”, it should be used to alert the rider that the software has overridden user input for safety reasons. Giving reckless, careless, or ignorant riders the option to blow off a warning doesn’t seem like a great idea.

The sudden stop issue is what leads to most accidents with these things.

Objects in motion want to stay in motion.

The board stopping doesn't mean the 140-250lbs jackass on top will stop moving.

Wouldn’t slowing down, while you’re leaning forward just forcefully dismount you, face first, on the pavement?

  I’m going to repeat what I said to another user:
  
  Do you seriously think I was talking about slowing down abruptly enough to hurt people? Do you understand that it’s possible to slow down just by cutting power to the motor and coasting to a stop? Have you ever ridden a bicycle or driven a car?

    You shouldn’t be so rude when you’re just dead wrong

    you move forward by leaning forward. The board’s acceleration counteracts the leaning while driving you forward in the process. If it stopped suddenly, the front end would suddenly lean too far forward and hit the ground.

    Due to the board’s, uh, ingenious one wheel design, when you lean forward, the motor must accelerate forward to counteract the force and keep self-balancing. Same with leaning backyard, the motor must accelerate backward (either slowing down or reversing) to keep you balanced. So, if you’re already leaning forward, it’s physically impossible for the board to decelerate without losing its self-balancing properties. In addition to that, if the motor is already on its peak speed and can’t accelerate any further, if you lean forward even more, the motor won’t have enough spare acceleration in order to counteract it and keep self-balancing, leading to crash. The firmware update seems to add some buzz/vibration to alert the rider when the motor is near its limit.

Automatically slowing down or stopping will absolutely get more people killed

    Have you ridden a OneWheel???

    Yes. Poorly and briefly, but yes.

    These are two to four wheel vehicles, not one wheelers.
    
    It's a whole different thing.

    In terms of balance, yes, but momentum still works the same way.

used to alert the rider that the software has overridden user input

I think this is the whole point. Riders were asking more of the boards than the boards could do, and when the board was unable to comply the rider would lose their balance. Haptic feedback tells the rider "nah, not doing that" so they're aware the board isn't going to do the thing and can adjust their balance accordingly.
