Robotiikassa, drooneissa ja vaikkapa robottipölynimurissa tarvitaan tarkkaa tietoa siitä, mitkä esineet ja esteet ovat laitteen ympärillä. TDK:n uusi MEMS-anturi osoittaa, miksi ultraääni on ylivertainen tekniikka näissä ToF- eli lentoaikaa mittaavissa sovelluksissa.

Uutuus kuuluu InvenSense SmartSonic -anturiperheeseen ja on mallimerkinnältään ICU-10201. MEMS-pohjainen komponentti sisältää tehokkaan sulautetun prosessorin ja laajennetun muistitilan, minkä ansiosta sovellusalgoritmeja voidaan ajaa suoraan itse anturilla.

ICU-10201-anturi tarjoaa tarvittavan herkkyyden tarkkaan esteiden välttämiseen tai läheisyystunnistukseen, jota käytetään usein robotiikassa, droneissa ja robottipölynimurilaitteissa (RVC). Se on erittäin tärkeä myös tuotteille, jotka vaativat tasotunnistuksen, kuten nesteannostelijassa tai kahvinkeittimessä.

SmartSonic-sarjan ToF-antureilla on pietsosähköinen ultraäänianturi, jonka virrankulutus on erittäin pieni. ICU-10201:lle on istutettu edeltäjiä tehokkaampi sulautettu prosessori, jonka ansiosta parannetut prosessointiominaisuudet mahdollistavat monenlaisten sovellusalgoritmien asentamisen ja suorittamisen sirulla. Tämä vapauttaa isäntäohjaimen muihin tehtäviin.

Anturi tuottaa millimetrin tarkkoja ja vankkoja etäisyysmittauksia kohteisiin jopa 1,7 metrin etäisyydellä kaikissa valaistusolosuhteissa, mukaan lukien täysi auringonvalo, riippumatta kohteen väristä ja tai läpinäkyvyydestä. Lasiseinät tai peilit eivät ultraääneen vaikuta.

ICU-10201 on pakattu 3,5 x 3,5 millimetrin koteloon. Lisätietoja täällä.

Suomen suurin valtti kybersodassa on luottamus

Teknologia19 – Aalto-yliopiston kyberturvallisuusprofessori Jarno Limnéll uskoo, että luotettavuudesta voi tulla suomalaisten yritysten suurin myyntivaltti tulevaisuudessa. – Tärkein kysymys on tulevaisuudessa, kehen ja mihin voimme luottaa. Luottamuksesta on tulossa hyvin arvokas aineeton pääoma yrityksille, Limnéll sanoi eilen messukeskuksessa.
