Calculation of the position (position : X, Y, Z) and direction (orientation: A, B, C are yaw, pitch, roll angles respectively) of the tool of the robotic arm relative to or to the user's Base Frame coordinate. The task when knowing the joint angles: A₁, A2, A3, A4, A5, A6 of the robotic arm is called Forward Kinematics, which will lead to the determination of the Homogeneous Transformation Matrix using all 5 formulas or Use the Robotics Toolbox for MATLAB to help (Note: angles in the formula are in radians (example radians = 180 degrees)).
