The pro\u00adduc\u00adtion halls are bustling: com\u00adpo\u00adnents must arrive at the pro\u00adduc\u00adtion line just in time, pack\u00adaging mate\u00adrials at the pack\u00adaging machine, pal\u00adlets in the ware\u00adhouse. Rail-bound sys\u00adtems such as classic AGV sys\u00adtems are sim\u00adilar to trains or trams and follow pre\u00adde\u00adfined routes. Freely \u00adnav\u00adi\u00adgating vehi\u00adcles, so-called autonomous mobile robots (AMR), have flex\u00adible route deter\u00admi\u00adna\u00adtion. Together with the people, other AGV \u00adsys\u00adtems and machines in their dynam\u00adi\u00adcally changing envi\u00adron\u00adment, both types of AGV \u00adsys\u00adtems must be one thing above all: safe. But how does one best bring together pro\u00adduc\u00adtivity and safety in mobile robotics?<\/p>\n\n\n\n
\u201cThe com\u00adplexity of the AGV sys\u00adtems increases with their abil\u00adi\u00adties,\u201d states Manuel Sch\u00f6n, \u00adRobotics Product Man\u00adager at Pilz. \u201cMod\u00adular safety solu\u00adtions enhance pro\u00adduc\u00adtivity indi\u00advid\u00adu\u00adally for each appli\u00adca\u00adtion.\u201d Rail-bound AGV sys\u00adtems must main\u00adtain defined warning and safety zones according to their speed, which can lead to a stop in the event of an obstacle, for example. The safety laser scanner PSEN\u00adscan from Pilz per\u00adforms this type of safe\u00adguarding and, at the same time, the pro\u00adduc\u00adtive area mon\u00adi\u00adtoring for col\u00adli\u00adsion pro\u00adtec\u00adtion. If addi\u00adtional safety func\u00adtions such as the emer\u00adgency stop are to be cov\u00adered, there is a flex\u00adible solu\u00adtion package com\u00adprising PSEN\u00adscan and the mod\u00adular safety relay myPNOZ.<\/p>\n\n\n\n
\u201cFreely nav\u00adi\u00adgating mobile plat\u00adforms can drive around obsta\u00adcles or people without stop\u00adping. As a result, the required safety func\u00adtions are more com\u00adplex,\u201d explains Sch\u00f6n. Safe laser scan\u00adners thus con\u00adstantly reg\u00adister their sur\u00adround\u00adings. The data can be directly read out via the ROS (Robot Oper\u00adating System) pack\u00adages from PSEN\u00adscan. Users can use these for their own SLAM algo\u00adrithm (Simul\u00adta\u00adneous Local\u00adi\u00adsa\u00adtion and Map\u00adping), thereby cre\u00adating maps of the envi\u00adron\u00adment for the nav\u00adi\u00adga\u00adtion.<\/p>\n\n\n\n
\u201cPSEN\u00adscan has up to 70 pro\u00adtected fields, which allows dynamic pro\u00adtected field adjust\u00adment: These safety zones are larger at high speeds to detect obsta\u00adcles in good time. And shorter at slow speeds to avoid stand\u00adstills when\u00adever pos\u00adsible,\u201d states Sch\u00f6n. \u201cThis allows the AGV system to move effi\u00adciently.\u201d The con\u00adfig\u00adurable small \u00adcon\u00adtroller PNOZ\u00admulti with motion mon\u00adi\u00adtoring module (expan\u00adsion module for drive mon\u00adi\u00adtoring) reli\u00adably per\u00adforms the selec\u00adtion of the cor\u00adre\u00adsponding safety zone.<\/p>\n\n\n\n
\u201cAGV sys\u00adtems com\u00admu\u00adni\u00adcate wire\u00adlessly with their master con\u00adtroller in pro\u00adduc\u00adtion halls,\u201d says Sch\u00f6n. \u201cThis makes them sus\u00adcep\u00adtible to external attacks or manip\u00adu\u00adla\u00adtion. Map data can be queried, and in the worst case AGV sys\u00adtems and thus ongoing pro\u00adduc\u00adtion can even be stopped.\u201d Indus\u00adtrial secu\u00adrity from Pilz is on board. The indus\u00adtrial fire\u00adwall Secu\u00adri\u00adty\u00adBridge \u00adreli\u00adably ensures that no unau\u00adtho\u00adrised par\u00adties can access the internal IT net\u00adwork of the mobile plat\u00adform during oper\u00ada\u00adtion. Making mod\u00adular safety \u2013 and secu\u00adrity \u2013 work, even when mobile!<\/p>\n\n\n\n
