How to use Simulink with ROS

Hey!

Im trying to connect the line estimate SOC to publish the ROS node but error keeps occuring, can someone please help me with this?

"

One or more signal names in the input bus to block 'BatterySOCEstimation/Publish/SignalSpecification' does not match the signal names in the bus specified by the bus object 'SL_Bus_BatterySOCEstimation_std_msgs_Float64' on the block dialog. Signal Specification blocks always treat element name mismatches as errors, regardless of the 'Element name mismatch' option setting. Either change the specified bus object or rename the input bus element signals to match the bus object.

It looks like an element name mismatch problem. I can only say that you should follow the instruction in the error message. Otherwise, can you share the model and reproduction steps so that other contributors can investigate the issue in detail?

Hey there!

I use the example of getting the SOC from simulink example lists. Then i just tried to publish the estimate SOC to a ROS node by simply connect the line to a bus creator then to a ROS publisher with std_message/Float32 (this might be the problem in the type conversion?). I noticed the naming mismatch error but i dont know how to fix it cause it didnt really show me how to change the name nor did i know how to do it

Hi Bao,

Please reach out to MathWorks Technical Support Team as you need to share your Simulink models.

Thanks,
