If i have 2D path, generated from a map. and I want to animate a robot following this path and some obstacles moves randomly in the is map

The obstacles can moves in all evironment and i can control the number of moving obstacles

Hello mohammed alany,
As per my understanding, you have a 2D path for a robot. You would like to have N number of obstacles that move randomly in the environment, and you would like to visually see this in action.
Please refer to the demo code below. I have used an ‘occupancyMap’ in this example to showcase the animation as it visually looks the most similar to the example image you have provided. Alternatively, you could also create a ‘robotScenario’ or use ‘dynamicCapsuleList’. In the code below, I have generated N=10 obstacles and moved them all diagonally upwards. You can modify the code to have each obstacle’s location be updated based on your requirement and kinematic constraints. I have set the path of the robot to move from (90,90) to (50,50). The robot is the only one moving diagonally downwards in the example. Do consider increasing timeSteps and decreasing the change in value per timeStep to have a smoother animation. But this will come at the cost of some extra performance.
%create a list of starting locations for n obstacles
path=[pathX' pathY'];
for i=1:timeSteps
map = occupancyMap(zeros(100,100));%clear map
updateOccupancy(map,obstacleStartLocation,ones(10,1));%add obstacles to map
updateOccupancy(map,path(i,:),1);%add main path point for current time step
inflate(map,0.5);%make point bigger as per size of obstacles
%update path of other obstacles randomly. I am just moving them
%diagonally upwards in this example. please change it as per your
for j=1:n
