draw a 3d robot in matlab

To draw a 3D robot in MATLAB, you can use the built-in graphics functions provided by the software. Here is some sample code that demonstrates how to draw a simple 3D robot:


main.m
% Define the robot's body
body = [0 0 0;
        0 0 10;
        10 0 10;
        10 0 0;
        0 0 0;
        0 10 0;
        0 10 10;
        0 0 10;
        0 10 10;
        10 10 10;
        10 0 10;
        10 10 10;
        10 10 0;
        10 0 0;
        10 10 0;
        0 10 0];

% Define the robot's arms
left_arm = [10 0 0;
            10 0 5;
            10 -5 5;
            10 -10 10];
right_arm = [10 0 0;
             10 0 5;
             10 5 5;
             10 10 10];

% Define the robot's legs
left_leg = [0 0 0;
            0 0 -5;
            -5 0 -5;
            -5 0 -10];
right_leg = [0 0 0;
             0 0 -5;
             5 0 -5;
             5 0 -10];

% Plot the robot
hold on;
plot3(body(:,1), body(:,2), body(:,3));
plot3(left_arm(:,1), left_arm(:,2), left_arm(:,3));
plot3(right_arm(:,1), right_arm(:,2), right_arm(:,3));
plot3(left_leg(:,1), left_leg(:,2), left_leg(:,3));
plot3(right_leg(:,1), right_leg(:,2), right_leg(:,3));
axis equal;
xlabel('X');
ylabel('Y');
zlabel('Z');
view(3);
hold off;

This code defines the robot's body, arms, and legs as sets of vertices in 3D space. It then uses the plot3() function to plot these vertices and connect them with lines to form a 3D shape. The axis equal command ensures that the plot is drawn to scale, while the view(3) command sets the camera angle to a standard 3D view. You can modify the vertex coordinates to change the shape and appearance of the robot.
