Simscape Vehicle simulation for predefined time, X,Y and orientation values

Hello everyone,

I have a table containing info as follows:

 dateTime              X         Y       theta 
    _______________________    ______    ______    ______

    03.05.2023 00:00:00.000    33.441    68.328    316.77
    03.05.2023 00:00:00.100    33.441    68.328    316.77
    03.05.2023 00:00:00.200    33.441    68.328    316.77
    03.05.2023 00:00:00.300    33.441    68.328    316.77
    03.05.2023 00:00:00.400    33.441    68.328    316.77
    03.05.2023 00:00:00.500    33.441    68.328    316.77
    03.05.2023 00:00:00.600    33.441    68.328    316.77
    03.05.2023 00:00:00.700    33.441    68.328    316.77

And I have a stl CAD for my vehicle.

is there is a way to make a simscape simulation using my time while putting the X,Y and orientation as inputs for the motion of the vehicle? Also can I make the simulation run faster than the actual time I am using?

Thank you.

Hii,

You can create a Simulink/Simscape simulation by importing the cad model using Simulink multibody. Use your input data to define the position and orientation of the vehicle at each time step of the simulation. You can do this by using a MATLAB Function block in Simulink to read your input data and output the position and orientation of the vehicle as a function of time. . You can use the Simscape Multibody animation tools or MATLAB plotting functions to visualize the motion of your vehicle over time.

For More info you can refer to the following documentation:

Hello @Manas,

Thank you for reply. Sorry I didn't clarify that I already have some experience with the Simscape Multibody, that's why I mentioned .stl because I know it is acceptable by this libaray.

I am more interested about the part where I use the given time instead of simulation time. So if you can elaborate more on the MATLAB Function code I would be grateful.

N.B. I already use readTable function to read the file. And I have the each type of data stored in 4 different variables.
