Simulate autonomous robot with distance sensors

I would like to simulate a robot with obstacle detect sensors(ultrasonic or infrared) as in the below video: https://www.youtube.com/watch?v=dDgJFtziJRQ

or this: https://www.youtube.com/watch?v=x57SXD2xl5E

I have seen some papers and see that lots of people using MATLAB as simulator for autonomous robot controlling task. However I didn't find any distance sensors in Simulink or MATLAB functions. There are some third side tools developed sensors, but what I want to do is design my own robot as in the video, which I can determine the number and position of sensors on the robot.

I bet MATLAB have support this functions, for so many people select it as prior selection for simulation.

Does anyone now how to do the simulation task in the video? Thanks a lot!

I want to do the same thing, except I would like to implement it from scratch, have you found anything useful ?

Actually, MATLAB does not yet have an official built-in robotics simulator. However, there is a lot out there you can use as a starting point.

Georgia Tech has made a really nice one called Sim.I.Am, which you can find here: https://www.mathworks.com/matlabcentral/fileexchange/40860-sim-i-am

Cornell has one too: https://sourceforge.net/projects/createsim/

One of my colleagues has also made a Simulink based toolbox for 2D mobile robots which you could leverage: https://www.mathworks.com/matlabcentral/fileexchange/62961-student-competition-mobile-robotics-training-toolbox?focused=7657987&tab=function
