% A serial link manipulator comprises a series of links. Each link is described

% by four Denavit-Hartenberg parameters.

%

% Let's define a simple 2 link manipulator. The first link is

>> L1 = Link('d', 0, 'a', 1, 'alpha', pi/2)

L1 =

theta=q, d= 0, a= 1, alpha= 1.571, offset= 0 (R,stdDH)

% The Link object we created has a number of properties

>> L1.a

ans =

1

>> L1.d

ans =

0

% and we determine that it is a revolute joint

>> L1.isrevolute

ans =

1

% For a given joint angle, say q=0.2 rad, we can determine the link transform

% matrix

>> L1.A(0.2)

ans =

0.9801 -0.0000 0.1987 0.9801

0.1987 0.0000 -0.9801 0.1987

0 1.0000 0.0000 0

0 0 0 1.0000

% The second link is

>> L2 = Link('d', 0, 'a', 1, 'alpha', 0)

L2 =

theta=q, d= 0, a= 1, alpha= 0, offset= 0 (R,stdDH)

% Now we need to join these into a serial-link robot manipulator
