Thanks

Please i am still getting this error after deleting the soft realtime block

The "FixedStepDiscrete" solver cannot be used to simulate block diagram 'untitledfcn' because it contains continuous states

Component:Simulink | Category:Block diagram error

and also after converting to a variable solver, i got this error

Error in 'untitledfcn/Robot Simulator': Initialization commands cannot be evaluated.

Caused by:

Changing property 'SolverType' is not allowed

Component:Simulink | Category:Block error

kindly assist, thanks

This error usually occurs when you don't run the file "installMRTToolbox" included in the training files. This should be on the main directory for the submission here:

https://www.mathworks.com/matlabcentral/fileexchange/62966-student-competition-mobile-robotics-training

You will need a compiler to compile the s-funciton for the block and then everything should work. This is prompted when the install file is executed.

Alternatively, if you are using MATLAB R2018a or newer you can delete the block form the library and use Simulation pacing instead. To do this:

Right-click the Robot Simulator and select Library Link>Go to library block
Unlock the library by clicking the lock on the bottom left corner
Right-click the Robot Simulator block in the library and select Mask>Look under mask
Delete the "Soft Real Time" block
Save the library

You can enable Simulation Pacing from the run button. This will slow down the simulation to real-time speed.

Find here more details on simulation pacing:

Adentro de el bloque "Robot Simulator". Para que la solucion sea permanente, debes editar la libreria donde se encuentra el bloque. Se puede abrir la libreria con este comando:

>>open_system('mobileRoboticsTrainingLib')
