Week 2- 2R Robotic Arm Challenge

% inputs 
l1=1
l2=0.5
theta1=linspace(0,90,30);
theta2=linspace(0,90,30)
ct = 1

these are the input variables

l1 and l2 are the length of link 1 and 2 respectively

theta1 and theta2 are the angle that the link 1 and link 2 makes

for i=1:length(theta1)
    THETA1 = theta1(i)
    for j = 1:length(theta2)
        THETA2 = theta2(j)
x0 = 0;
y0 = 0;      

x1 = l1*cosd(THETA1);
y1 = l1*sind(THETA1);

x2 = x1+l2*cosd(THETA2);
y2 = y1+l2*sind(THETA2);

here the value of theta1 and theta2 are changed automaticaly using a for loop

% plotting
plot([x0 x1],[y0 y1],[x1,x2],[y1,y2],'linewidth',3)
axis([-0.1 1.5 0 1.5])
 pause(0.03)
 M(ct) = getframe(gcf);
 ct = ct+1;
    end
end

all the combinations of link1 and link 2 is plotted

movie(M)
videofile = VideoWriter('forward_kinematics.avi','Uncompressed AVI');
open(videofile)
writeVideo(videofile,M) 
close(videofile)

A videofile of the combinations are made
