You are asked to design a robot that can right itself once it is left to free-fall. Bioinspired from a cat, specify the hardware components and the minimum number of body segments that are needed to achieve this task. Qualitatively state the “relative” magnitudes of each segment Moment of Inertia and segment rotational acceleration. As the free-fall height increase (less time for segmental rotations), will the power required by the moment (torque) actuators increase or decrease? Please justify your answer using Newton’s 2nd law: Net Muscle Moment = (Segment Moment of Inertia) * (Rotational acceleration)
