Introduction

ある年の暮れのことです。自信家のエンジニアが、こう言いました。ロボットに脚なんて飾りです。偉い人にはそれがわからんのです。気に入らなかった私は、飾り気のない脚だけの玩具を作ることにしました。

ASIBO is an expression device that shifts its behavior in accordance with the switching frequency and timing of the solenoid. ASIBO looks like a pile driver and behaves like one. However it changes this behavior when the user/system switches its solenoid rapidly. ASIBO is designed as an actuator of a toy, robot, marionette and drum machine.


Component

ASIBO


アシボは、12Vソレノイド・バネ(長さ10mm)・タミヤ製トラックタイヤ・アクリルブーム(厚さ2mm)ほかで構成されています。ソレノイドのスイッチングは手動と自動の両方で行うことができます。

ASIBO itself consists of a 12VDC tubular pull solenoid, a coil spring (approximately 10 mm in length), a toy car's truck tire, and some acrylic booms (2mm thickness). The solenoid of ASIBO can be switched manually or by a computer.

 

Double ASIBO & Vibrant ASIBO

二台のアシボを先で繋げば、タップダンサーへと早変わり。アシボは身体を左右に揺らし、カチカチ地面を鳴らします。二台を同時にスイッチすれば、あららアシボは股を開きます。そして交互にスイッチすれば、アシボは股を閉じるのです。

アクリルブームを斜めにつければ、アシボは前へと進み出します。スイッチングスピードがあがるにつれて、アシボの歩みは速くなります。しかしスイッチングが「あるスピード」に達すると、突如としてアシボは後退を始めるのです。

ASIBO

Double ASIBO is a tap dancing marionette with which two sets of ASIBOs’ are connected at their upper point. This tap dancer shakes its body from side to side by the alternate switching of each solenoid, and stamps the ground. Moreover, this tap dancer can open its legs according to the resultant force gained by the simultaneous switching of the solenoids. Its legs spread faster depending on the raising of the switching frequency. When the user/system switches the solenoid at a certain high speed and alternately, the tap dancer shifts to close its legs.

By changing the composition of the acrylic booms to shake its tip, ASIBO can move forward by the inertial force of the shaking. For example, ASIBO walks lightly when the switching frequency by the computer is 240 BPM (On: 50ms OFF: 200ms). And ASIBO walks faster with the increasing pace of the frequency. When the frequency reaches approximately 800 BPM (ON: 50ms OFF: 25ms), ASIBO begins to glide over the floor due to the heavy vibration. ASIBO shifts to go astern at a stable speed when the frequency is raised to approximately 1760 BPM (ON: 16ms OFF: 18ms).
