Postural control of a falling cat was investigated analytically and experimentally. The authors intended to develop such a robot as a cat that could restore her attitude at free fall by twisting and controlling the body. There are still contradictory and ambiguous explanations among the text books of physics or dynamics which deal twisting motion of a cat. Firstly, the principle of the twisting motion of a robot cat was analysed using a jointed double column model. And it was made clear analytically that a cat could restore her attitude by bending and twisting the body in the air. Then, the authors developed the robot cat which had vertebrate-type backbones and twisting mechanisms. It was confirmed experimentally that the robot cat could control its attitude by 180 degrees' rotation within 0.6 second when it was released upside-down at about 1.8m height in the air.

In this paper, we present a water volume estimation method in various cups using the glass harp acoustics. When a rigid probe flicks a glass, sounds arise. Since the sounds alter depending on the water volume in the glass, we can utilize the sound information to estimate the water volume. In order to model the acoustics characteristics of various glasses, we propose the relational expression between the water volume and the vibration frequency that improves Oku's expression. By using the proposed relational expressions and a flicking motion by a robotic finger with a microphone, we confirm the proposed method can estimate the water volume with the accuracy of 1–3%.
