Bhead Jones Posted June 28, 2019 Share Posted June 28, 2019 I LOVE LOVE LOVE my Mini Pro. I have ridden over 2k miles on it. There is a SERIOUS design flaw, easily remedied by a firmware update. I was riding out of my driveway. My wife's car was parked with its fron wheel slightly turned out. As I rode past, the right wheel of my mini-pro brushed up against the tire of the car. When that happened, the left wheel of my mini-pro ACCELERATED, AND literally hurled/ejected my from the platform. I landed a couple of feet away on the driveway, fracturing my hip/femur. This is an easily foreseeable, and easily remedied defect. When one wheel is stopped, the other wheel of the mini-pro should no be permitted to turn at the maximum rate. There should be a governor, just as there is for top speed. The other (obvious) answer is for the fender to actually come over the top of the mini-pro tire so that it is more difficult to encounter a parallel obstacle. that's all I gotta say... 1 Quote Link to comment Share on other sites More sharing options...
trevmar Posted June 28, 2019 Share Posted June 28, 2019 Sounds like the same problem discussed in this topic: 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Philip Posted June 29, 2019 Popular Post Share Posted June 29, 2019 I'm sorry to hear about your accident. I've been riding self-balancing machines for 17 years now, and the behaviour that you described is just what they do the instant one wheel strikes a resistance. I can't think of a way of changing the algorithm to prevent this. From the machine's perspective, it is simply doing what it is designed to do - which is stay self-balanced, and to respond to pitch and yaw instructions from the rider. The machine cannot "know" the difference between when the rider has just struck a solid object with one wheel, and when it has encountered a resistance for which applying extra torque is desirable (such as riding into a pothole or striking a bump). 1 3 Quote Link to comment Share on other sites More sharing options...
jojo33 Posted June 29, 2019 Share Posted June 29, 2019 (edited) In this situation, I also experimented, it is necessary to adopt the reflex to eject itself by the back, a small jump, in all cases the problem remains in the posture of the feet, pressing the pads, removing the pressure of a foot is not enough, you have to eject yourself In fact, the sensor processing time is long, it can take 1,5 second ...The order given by the pressure of the feet is not instantaneous We can observe this latency when we quickly go down the Miniand raise it quickly Edited June 29, 2019 by jojo33 1 Quote Link to comment Share on other sites More sharing options...
