Error evaluating 'InitFcn' callback of block_diagram: block_diagram does not have a parameter named 'SimMechan​icsRigidly​BoundBlock​'

65 visualizaciones (últimos 30 días)
After installing Simulink and ROS Toolbox, I attempted to run the first command from the first tutorial titled "Exploring a ROS Network", found in the "MATLAB and Simulink ROS Tutorials" add-on:
I then received the following error:
Error evaluating 'InitFcn' callback of block_diagram 'RP_ROS_robot'. Callback string is 'RPInit set_param([gcs '/RP ROS™ Robot/Enabled'],'Value','1') RP_ROS2_srv_eStop'
Caused by:
  • block_diagram does not have a parameter named 'SimMechanicsRigidlyBoundBlock'
I didn't set up any of the parameters, since I'm following a tutorial. MATLAB, Simulink, and ROS Toolbox are all on the most recent version (R2022b). Could this result from some sort of version compatibility issue, and is there any way I can correct it and continue with the tutorial?
(I came across this older post and also tried installing Robotics Playground just in case that was the cause, but still get the same error.)
Thank you!

Here are two things you might want to check on:
  1. Make sure you have Simscape Multibody installed
  2. If the probem persists after installing Simscape Multibody, find the Simulink model that contains the Simulation environment and refresh the preferences by doing this:
  • >>open_system('RP_ROS_robot')
  • Navigate to the "" block and click the small arrow on the lower left corner
  • Save and close the model

Looks like the tutorials also require Navigation Toolbox. Try installing that also. We will make sure the requirements are updated on the File Exchange page.

Perfect! Installing the Navigation Toolbox resolved the error "when invoking 'setupImpl' method of 'LidarSensorRP'". Thanks very much!

I'd like to share a hint to Chinese Learner.
Do not use Chinese characters in the path of your ROS tutorials.
Then the problems disappear instantly.
