Festo Bion­icFinWave

HWM (Singapore) - - CONTENTS - By Alvin Soon

This is not an un­der­wa­ter ro­bot you’ve seen be­fore. The Festo Bion­icFinWave is mod­eled af­ter the cut­tle sh, which uses its ns to gen­er­ate con­tin­u­ous waves for mo­tion. This me­chan­i­cal cephalo­pod uses two Zex­i­ble side ns, cast from sil­i­cone, to do the same thing.

The ns are fas­tened to nine lever arms, which are driven by two ser­vo­mo­tors. The two ns can move in­de­pen­dently and gen­er­ate a va­ri­ety of wave pat­terns. This en­ables the Bion­icFinWave to ‘swim’ in mul­ti­ple di­rec­tions, with a pre­ci­sion of move­ment that causes lit­tle tur­bu­lence.

This isn’t the rst Festo na­ture-in­spired ro­bot. The com­pany has cre­ated bat, spi­der, and drag­onZy ro­bots, as well as one dis­turb­ing oc­to­pus-like ro­bot ten­ta­cle arm. It’s not con rmed yet what life the Bion­icFinWave will have af­ter its re­veal. But its skills might make the Bion­icFinWave an as­set for un­der­wa­ter in­spec­tion and ex­plo­ration.
