Hi, i konw we can get information from PIX by python. And i have get some information,such as pitch,pitchspeed.I want to know can we get acceleration and angular acceleration information in three directions.If so,what is the type in the code? master.recv_match(type='ATTITUDE', blocking=True).to_dic…

Hi @Richard1 , I believe you’re after SCALED_IMU2 , as covered here: [image] Obtaining BlueROV2 IMU Readings Via Pymavlink Modifications Hi @CBW3750 , I just tried this and the new broadcast already sends both the SCALED_IMU2 and RAW_IMU messages by default, so you should b…

I try your code,i find that the result have nine sets of parameters，xacc,yacc,zacc,xgyro,ygyro,zgyro,xmag,ymag,zmag. I compare the result between this and type=attitude,i find pitchspeed,rollspeed and yawspeed are different from any of the above nine groups. So which are linear accleration,which …

The descriptions and units are provided in the mavlink docs: SCALED_IMU2 ATTITUDE (see also: VFR_HUD ) I’m unsure why the gyro measurements are different from the attitude speeds (outside of the factor of 1000 from the mrad/s vs rad/s units difference), so I’ve asked internally for ideas. I chec…

Well,i know information about angular velocity. But the data about xacc confuse me. Because the data is always changing when pix is fixed. [CDCP2538B$C{6QC9M0ICIG]

All sensor measurements have some level of noise, and accelerometers are no different. Once again it’s helpful to plot the data while moving the ROV (or at least moving the flight controller) to get a sense of the scale of the readings and their variations due to noise compared to those due to actua…
