How do you calculate DH parameters for a robotic leg?

How are the DH parameters calculated for the specific joint configuration (e.g., hip, knee, ankle) of a robotic leg?

Define a kinematic chain from the hip (base) to the foot. For each joint (e.g., hip, knee, ankle), assign Denavit-Hartenberg (DH) parameters: link length (a?), twist (α?), offset (d?), and joint angle (θ?). Follow the standard DH convention, aligning Z-axes along joint axes and X-axes along common normals between them.
