Mobile Robot Simulation In MATLAB

Mobile Robot Simulation in MATLAB is really hard to get it done from your end, it is always best to approach our developers to get best research outcomes. Developing a simple mobile robot simulation is an intricate as well as compelling process that must be carried out by adhering to several guidelines. As a means to conduct this process in MATLAB, we offer a procedural instruction, encompassing Simulink and MATLAB code:

Procedural Instruction to Mobile Robot Simulation in MATLAB

1. Specify the Robot Model

For a basic differential drive robot, we have to develop a kinematic model. On the basis of the wheel speeds, the motion of the robot has to be specified by this model.

% Define robot parameters

wheelRadius = 0.1; % Radius of the wheels (m)

wheelBase = 0.5;   % Distance between the wheels (m)

% Initial conditions

x0 = 0;  % Initial x position (m)

y0 = 0;  % Initial y position (m)

theta0 = 0; % Initial orientation (rad)

% Time parameters

t0 = 0;  % Initial time (s)

tf = 20; % Final time (s)

dt = 0.1; % Time step (s)

time = t0:dt:tf; % Time vector

% Control inputs (left and right wheel velocities)

vl = 0.5; % Left wheel velocity (m/s)

vr = 0.5; % Right wheel velocity (m/s)

2. Execute the Kinematic Model

The kinematic model of the differential drive robot must be executed by means of MATLAB.

% Initialize state variables

x = x0;

y = y0;

theta = theta0;

% Initialize arrays to store the results

xArray = zeros(size(time));

yArray = zeros(size(time));

thetaArray = zeros(size(time));

% Simulation loop

for i = 1:length(time)

% Update state

xArray(i) = x;

yArray(i) = y;

thetaArray(i) = theta;

% Compute the robot’s velocities

v = (wheelRadius / 2) * (vl + vr);

omega = (wheelRadius / wheelBase) * (vr – vl);

% Update the state using the kinematic equations

x = x + v * cos(theta) * dt;

y = y + v * sin(theta) * dt;

theta = theta + omega * dt;

end

% Plot the robot’s trajectory

plot(xArray, yArray, ‘b-‘, ‘LineWidth’, 2);

xlabel(‘X Position (m)’);

ylabel(‘Y Position (m)’);

3. Include Control Input Variations

In order to depict various motion activities, we should alter the control inputs.

% Varying control inputs

vlArray = 0.5 + 0.1 * sin(time); % Left wheel velocity (m/s)

vrArray = 0.5 + 0.1 * cos(time); % Right wheel velocity (m/s)

% Reinitialize state variables

x = x0;

y = y0;

theta = theta0;

% Simulation loop with varying control inputs

for i = 1:length(time)

% Update state

xArray(i) = x;

yArray(i) = y;

thetaArray(i) = theta;

% Compute the robot’s velocities

vl = vlArray(i);

vr = vrArray(i);

v = (wheelRadius / 2) * (vl + vr);

omega = (wheelRadius / wheelBase) * (vr – vl);

% Update the state using the kinematic equations

x = x + v * cos(theta) * dt;

y = y + v * sin(theta) * dt;

theta = theta + omega * dt;

end

% Plot the robot’s trajectory

4. Path Planning and Following

A basic path scheduling and following technique has to be applied. To track the path, we utilize a Proportional (P) controller and a collection of waypoints in this instance.

% Define waypoints for the robot to follow

waypoints = [0 0; 2 2; 4 0; 6 2; 8 0];

numWaypoints = size(waypoints, 1);

% Control gains

kp = 1; % Proportional gain

% Reinitialize state variables

x = x0;

y = y0;

theta = theta0;

% Initialize arrays to store the results

xArray = zeros(size(time));

yArray = zeros(size(time));

thetaArray = zeros(size(time));

% Simulation loop for path following

for i = 1:length(time)

% Update state

xArray(i) = x;

yArray(i) = y;

thetaArray(i) = theta;

% Find the nearest waypoint

[~, nearestWaypointIdx] = min(sqrt((waypoints(:, 1) – x).^2 + (waypoints(:, 2) – y).^2));

target = waypoints(nearestWaypointIdx, :);

% Compute the control inputs

errorX = target(1) – x;

errorY = target(2) – y;

distanceToTarget = sqrt(errorX^2 + errorY^2);

angleToTarget = atan2(errorY, errorX);

angleError = angleToTarget – theta;

v = kp * distanceToTarget; % Linear velocity control

omega = kp * angleError; % Angular velocity control

% Limit the control inputs

v = min(v, 1); % Limit the linear velocity

omega = min(max(omega, -pi/4), pi/4); % Limit the angular velocity

% Update the state using the kinematic equations

x = x + v * cos(theta) * dt;

y = y + v * sin(theta) * dt;

theta = theta + omega * dt;

end

plot(xArray, yArray, ‘b-‘, ‘LineWidth’, 2);
