How can I make an animating plot moving with the speed I predefined?

Hello, I am trying to make a simple simulation of a robot following straight lines. I am using a plot function and I would like to know how to make the robot in the plot move with the speed I want (ex. 2 m/s or 5 m/s)
Thank you!

One way would be to update the coordinates of the robot according to the velocity after each iteraion.

This is a very basic/crude example, but it shows some basic concepts:
y0 = 0; % Starting location
v0 = 100; % Starting velocity
a = -10; % Acceleration
p = plot(0, y0, 'o');
xlim([0 25])
ylim([0 600])
drawnow
t0 = datetime(); % Get the starting time.
tnow = t0;
while (tnow - t0 < minutes(1) && p.YData >= 0)
t = seconds(tnow-t0); % How much time has passed?
p.XData = t;
p.YData = y0 + v0*t + 0.5*a*t.^2;
drawnow
tnow = datetime(); % Get the current time
end

Once you get that working, you may want to look into either timer or backgroundPool so you can run the simulation without blocking the MATLAB command window (for example Background Processing).
