M7-2 表面張力を利用した水面移動ロボットの研究(M7 ナノ・マイクロシステム)

This paper discusses biomimetic water strider robots that have microfabricated hydrophobic legs. Lift, pull-off and thrust forces of the supporting legs have been measured. Water strider robots were developed using MEMS (micro electromechanical systems) The robot successfully walked in the tripod gait at 300 mm/min, and also moved on the surface of water at 600 mm/min.

表面張力を利用した水面移動ロボットの研究(機械力学,計測,自動制御)

This paper describes a bio-mimetic water strider robot with microfabricated hydrophobic legs. Various kinds of supporting legs with hydrophobic microstructures on their surfaces were developed using MEMS (Microelectromechanical Systems) techniques. The lift and pull-off forces of these supporting legs were analyzed theoretically and then measured. The experimental results were in good agreement with the calculations. Water strider robot with twelve micro-fabricated legs driven by a vibration motor successfully moved on a water surface and also made left/right turns by exploiting differences in the resonant frequencies of the legs.

1P1-O06 表面張力を利用した水面移動ロボットの研究(MEMSとナノテクノロジー)

This paper describes a biomimetic water strider robot with microfabricated water-repellent legs. Various kinds of supporting legs with water-repellent microstructures on their surfaces were developed utilizing microfabricaion techniques. Lift and pull-off forces of the supporting legs have been measured. The experimental results are in good agreement with theoretical values. Furthermore, an autonomous water strider robot with twelve microfabricated legs has been developed. A vibrating motor is utilized to move the legs for controlled locomotion. The robot can successfully stay afloat by surface tension and can also move forward and make left/right turns utilizing differences of resonant frequencies of the legs.

The stability of the water surface movement mechanism of the water strider is higher than that of the ship etc. Moreover, it is easy for this mechanism to move in the shoal and to turn rapidly. In addition, this mechanism can be moved in both land and water. Therefore, it is desirable to apply this mechanism to a rescue robot and a limited environment exploration robot. In this study, we developed the water strider robot with a servo motor controlled by the radio controller, and discussed fundamental characteristics of the motion patterns.
