4. 1. Show the sketch of a spherical robot.
   2. A robot is having a rotation about the global coordinate frame Z by an angle of 300, then rotation about the global coordinate frame Y by an angle of 500, then translation about the global coordinate frame x by 10 units then give the final position of link with respect to the base of the robot after taken up the above movements.

5. The links of an RP manipulator shown in figure below have inertia tensors:

   c11 = 0. 0 0

   0 lyy1 I0 0 0
   0 Ixx2
   0 0 Izz1 lyy2 0 0 0 Izz2 and total mass m1 and m2. The center of mass of link 1 is located at a distance l1from the joint 1 axis, and the center of mass of link 2 is at the variable distance d2 from the joint 1 axis. Use Lagrangian dynamics to determine the equation of motion for this manipulator.

   I would like to know if you have provided the complete code, based on all of your experience, knowledge, and wisdom for my requests.
