 To improve the walking speed for Robotis OP2, I conducted some initial research into theoretical maximum walking speed. Because humanoid locomotion algorithm is still a popular research area, there are limited resources on maximum walking speed for humanoid robots. Therefore, I began my research by looking into maximum walking speed for human. In the paper, "Walking and Running: Legs and leg movements are subtly adapted to minimize the energycosts of locomotion," R. McNeill Alexander proposed to model human walking algorithm with inverted pendulum. Using kinematics, Alexander proposed that maximum walking speed is limited by length of legs through this equation, V_max = sqrt(g*L) (g is the gravitational acceleration on Earth and L being length of leg). After applying this equation to calculate maximum speed for Robotis OP2, the length of robot's leg being 21.95 cm, the result is 146.74 cm/s.  To improve the walking speed for Robotis OP2, I conducted some initial research into theoretical maximum walking speed.
