Vibrations and weak construction of the camera mount #31

Open neilyoung opened 6 years ago

neilyoung commented 6 years ago

I'm having a strange experience with the camera mount. Even if I calibrate it correctly, once the server starts, the camera literally falls down. I need to calibrate it to point to the sky so that it points forward, once the server starts.

But this is not the main issue I have. The entire construction is constantly vibrating and it is absolutely not robust enough. I had a little accident and all the screws fixing the holder of the bottom servo have been pulled out.

But what is this with the vibrations? If I pan a little left or right, the vibration stops. This is pretty strange, as if the servo would constantly getting contradictory orders

The servo was defective. Replaced. Cheap crap, as it seems

did the replacement of the servo clear the shaking? bcoz i have the same problem and wanna know how to avoid it coz its the only problem i have ryt now advance thx

Partly. The massive vibrations were gone, but there are still sometimes situations, when the servos are producing strange howling noises. Meanwhile I have removed the camera mount and glued a RPI fisheye cam, which produce good results. The entire concept of steering by servos, which need to be calibrated, is not working well. I think they would be better off with a fixed gear and a steering which controls left and right wheels. Will give it a try on occasion.
