cant see the output data.

[yuval-dimri]

first of all, thank you for the well-documented repository.

I'm running demo.launch file, and I can't see any data in rviz(imu node status is - ok)
and when running $rostopic echo /imu/data - it returns nothing....

note: when running $rostopic list, I do see "/imu/data"

[MarzanShuvo]

it is doing the same for me. Did you find any solution?

[yuval-dimri]

Hey, yes you should use something called rosserial (or something with a similar name)
Which then let's you send any kind of data as any kind of topic to Ros using Rosserial node.
I can share my own Arduino code if you want.

Please......It would be a great help for me. Thank you so much.

Hi guys, is there any chance you can shed more light on how you got this package to interface with the mpu6050. When I run this node, it just hangs... no error message, no confirmation that node is running. Did you need to modify the arduino or node.cpp files in anyway to make this work? Thanks in advance!

[yuval-dimri]

Hey! I'm super sad for not having time to deal with it as much as I'd like to... But.... My real solution for using imu with Ros is using a realsense that contains one (built-in) (d435-i) Whats your use of the robot? Please inform me with more detail so I can maybe help you with a general solution... Please let me know!

Hey @yuval-dimri no problem! I know what it's like. That sounds like a good call. I'm trying to set up an 4 wheel differential drive agv with imu and GPS to provide a fused position estimate. My set up is rpi4b and arduino mega connected to mpu6050 hence the need to use the driver kindly provided by @fsteinhardt I'm using the arduino and ros code without any changes and I think my problem lies with the serial connection. I guess I need to run some more tests to make sure the serial connection is working properly. Frustrating though !🙆😅

Hey guys, I am trying this package and I still got Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino
anyone can help? I made sure from Port and Baud rate and still having same error
