Code :- 

%Kinematics of 2R robotic arm manipulator
clear all

%Inputs 
l1 = 1
l2 = 0.5; 
theta1 = linspace(0,90,10); 
theta2 = linspace(0,90,10);
ct = 1;
    
for i = 1:length(theta1) 
   THETA1 = theta1(i);
   for j = 1:length(theta2)
      THETA2 = theta2(j);
      x0 = 0; %Coordinates
      y0 = 0; %Coordinates

      x1 = l1*cosd(THETA1); %Coordinates
      y1 = l2*sind(THETA1); %Coordinates

      x2 = x1 + l2*cosd(THETA2); %Coordinates
      y2 = y1 + l2*sind(THETA2); %Coordinates
      
      plot([x0 x1],[y0 y1],[x1 x2],[y1 y2],'linewidth',3) %plot a graph
      axis([-0.1 1.5 0 1.5]) 
      pause(0.03)    
      M(ct) = getframe(gcf); 
      ct=ct+1;

end

movie(M)
videofile = VideoWriter('forward_kinematics.avi','Uncompressed AVI'); %Video File save
open(videofile)  %Video Open
writeVideo(videofile,M)
close(videofile)

 Output :-

Error facing while coding:-

While typing code for save video file :- 

syntax is 

videofile = VideoWriter('file_name,'Uncompressed AVI')

mistakenly i used wrong syntax.
