Question: Consider the robot manipulator shown in Figure 3. It has only two joints. Compute the equations of motion for this robot using Euler Lagrange formulation.

Consider the robot manipulator shown in Figure 3. It has only two joints. Compute the equations of motion for this robot using Euler Lagrange formulation. Please see Planar Elbow Manipulator example in Spong book to see what kinds of calculations are needed to solve this problem. Please note that this problem is different from the Planar Elbow Manipulator example because (1) two axes are perpendicular, and (2) two masses are point masses. Moment of Inertia Matrix for a point mass is zero matrix
