We have been developing motor-tendon-joint series connection type biomimetic soft actuators to make robots act jumping, running and dancing like animals. We developed an artificial silicone rubber tendon structure for the robot to mimic animal's muscular-skeletal structure. In the previous paper, we added an auxiliary motor to the one-axis jumping actuator to suppress the vibration at a fixed angle control. The vibration can be reduced by nipping between the main motor and the auxiliary motor. The experimental results of this actuator, however, showed that this structure had structural defects that the nipping force was restricted by the torque of the smaller motor at a fixed angle control stage, and the jumping force was also restricted by the movement of the slower motor. As a result, the jumping height of this actuator was decreased. In this paper, we newly developed an actuator mounted with the same twin motor to solve this problem. We used twin 200W DC coreless motors for the new actuator. The experimental results showed that we have succeeded in improving the simple jumping height up to 260 mm. It was, however, not possible to show the effectiveness of the tendon structure by bending and stretching jumping experiment. We are now creating a simulator of this actuator to investigate how to effectively utilize the tendon structure.

微生物を行動制御して生きたマイクロマシンとして利用するには,微生物用の作業用具を作成し,それを使う必要がある.本研究は,行動制御が可能なゾウリムシとミジンコに対して,作業用具を開発した.ゾウリムシに対しては,ポリプロピレン薄膜を使ったワッシャ状作業用具を開発し,それを取り付けることで,物体の搬送効率を向上させられることを実験的に示したが,その装着作業はとても困難で,今後解決する必要がある.ミジンコについては,接着した針で風船をパンクさせたり,ミジンコ用の注射器を作成し,それによりゼリーに薬液を注射させることに成功した.
