2 days ago i have started designing a car with 2 wheels, i want it to balance alone and control it with my phone. Ive built phone controlled cars before but none of which only had 2 wheels. I'm having trouble since i don't have the right components, instead of a gyroscope i have an accelerometer, G…

An accelerometer isn't ideal for detecting angular velocity like a gyroscope in a moving vehicle (assuming that if you call that a car, then it's moving) An accelerometer can measure tilt when the system is stationary or moving slowly. However, during faster movements, the accelerometer will also p…

if (acc > threshold){motorCompensate(back);} if (acc < -threshold){motorCompensate(forward);} Seems like a tuning nightmare - another data point like lidar/sonar or just a tilt switch would be invaluable.

Did you check any of the gazillon tutorials doing exactly that on google or youtube?

[image] zwieblum: doing exactly that exactly ? the ones I had seen often use a 6 DoF Module at minimum (like the MPU6050) — not just an accelerometer

Oh, there are. And they all suffer from oszillation problems due to not using gyro :slight_smile: BTW ... https://forum.arduino.cc/t/balancing-robot-drifting-issue-on-different-surfaces-forward-backward-drift/

[image] zwieblum: And they all suffer from oszillation problems due to not using gyro OK - so no need for the OP to spend time looking at that :wink:

Well, depending on his setup it might even work - well, kind of. And who knows, maybe he's smarter than those legions before him ...

You realize the internet is being burned as we speak. "Search for it" is less and less valuable advice. You are more likely to get a 15 year old answer regurgitated umpteen times by AI, that was wrong or irrelevant in the first place, than anything useful.

I'm aware of those facts, and since the car is controlled by the phone, if the car is moving linearly due a command sent by the phone then that motion will be disregarded

i have but non are using an accelerometer they are all using a MPU6050 chip which i dont have
