First, we create a dh table that lists all the parameters. In the table, we list the parameters below.

θ,α,a and d.

θ is the angle through which the xn-1 axis rotates through to be mapped onto xn (Corke, 2015).

α is the angle that you rotate zn-1 axis to map it onto zn axis (Corke, 2015).

a is the distance between the centers of the coordinates of two joints in the direction of the xn axis (Corke, 2015)

d is the distance between the centers of the coordinates of two joints in the direction of the zn-1 axis (Corke, 2015).

After analyzing the robot, we obtain the parameters and table them in a dh table.

* We use the Peter corke robotic toolbox to depict the robot on the MATLAB platform.

We create a variable L and include the dh parameters in it in the order: theta, d, a and alpha

L (1) =Link ([0 0 0 1.571]);

L (2) =Link ([0 0 1 0]);

L (3) =Link ([0 0 1 0]);

We employ the Serial Link toolbox function to generate a robot object and to store it into the workspace variable rob (Corke, 2015).

Rob=SerialLink(L);

According to (Corke, 2015), use the function Rob.name to name our robot.

Rob.name='question 1';

We apply the function Rob. Plot to produce a plot of the robot after

specifying the values of q in radians (Corke, 2015).

Rob.plot([0,0,0,]);

The robotic toolbox then produces the plot of the robot.

* The homogenous transformation matrix.

Typing rob in the workspace produces a dh table which lists all the essential parameters of the mechanism.

Rob =

We finally apply the function rob. fkine to carry out the forward kinematic evaluation of the robot and to yield a homogenous transformation matrix. From the homogenous matrix we can establish the rotation matrix of the end effector and its position (Corke, 2015).

Rob.fkine([0 0 0])
