With distal, middle, and proximal grace, Each phalange moves through its measured space. The index, middle, ring, and small all sway, Guided by flexion and extension’s play. DIP, PIP, and MCP align, In rhythmic cadence, in perfect time. From MetaCarpoPhalangeal joints they stand, Artful motions within a robotic hand. A thumb—oh, blessed opposable might, Five degrees, turning darkness to light. Through the distal, proximal, and metacarpal game, The CMC joint adds spark to the name. Abduction and adduction—a sway of flair, With graceful arcs dancing in air. Wrist Yaw, Pitch, and rotation anew, A journey of function breaking through. The Palm holds secrets, steadfast and grand, Balancing the intricate movements at hand. Twenty-two degrees, a marvel to see— One pitch for the wrist, setting it free. So 5 + 4 + 4 + 4 + 4 + 1, the numbers agree, All come together as 22 DoF decree. As wires and tendons trace the line, This robotic limb is a feat, divine. Let this ode sing forth with mechanical bliss, And praise the hand’s unstoppable twist.
