At EMBL Hamburg, structural research relies on cooperation between experts in different disciplines, including those in the <a href=\"https:\/\/www.embl.org\/groups\/fiedler\/\">Instrumentation Team<\/a>, which consists of physicists, mechanical and software engineers, and robotics experts. Together, they construct diverse instruments for X-ray-based structural biology tailored to the needs of users.<\/p>\n\n\n\n<p>Last year, a new transfer system has joined the MARVIN (MultiAxesRobotic-VersatileINstaller) robot family. The MARVIN system enables the quick and safe handling of fragile crystals, which are used by crystallographers to determine the structure of proteins.<\/p>\n\n\n\n<div class=\"vf-embed vf-embed--16x9 | vf-u-margin__bottom--400\">\n<iframe src=\"https:\/\/www.youtube.com\/embed\/01Hj0xgNYnA\" frameborder=\"0\" controls allowfullscreen><\/iframe><\/div>\n\n  \n<figcaption class=\"vf-figure__caption vf-u-margin__top--200\">Watch how the transfer robot MARVIN handles protein crystal samples step by step.

In each hole, it holds a pin that is used to collect protein crystals. The pucks are used to handle pins and crystals, and store them in liquid nitrogen. Credit: Stefan Fiedler\/EMBL<\/figcaption><\/figure>\n\n\n\n<p>The new MARVIN will accompany another machine, the <a href=\"https:\/\/www.arinax.com\/crystaldirect-automatic-protein-crystal-harvesting\/\">CrystalDirect&#x2122; Harvester<\/a>, which is <a href=\"https:\/\/www.embl.org\/groups\/macromolecular-crystallography\/user-information\/crystal-mounts\/\">already in operation at EMBL Hamburg<\/a>. The CrystalDirect&#x2122; technology consists of an extremely precise robot <a href=\"https:\/\/www.embl.org\/news\/science\/1604-crystaldirect\/\">developed at EMBL Grenoble<\/a> to automatically harvest protein crystals from <a href=\"https:\/\/www.embl.org\/groups\/marquez\/\">CrystalDirect<\/a>&#x2122; crystallisation plates onto tiny metal pins to then preserve them by cryo-cooling. This is far more convenient than handling crystals manually, and can also be done remotely. However, until now, users of the Harvester at EMBL Hamburg had to take the crystal-carrying pins in and out of the machine manually. They then had to place these pins one-by-one into storage containers \u2013 also known as pucks \u2013 which must be stored in liquid nitrogen at -196\u00b0C. During this tedious and time-consuming procedure, the precious samples could be accidentally mixed up, damaged or even lost.<\/p>\n\n\n\n<p>MARVIN makes the process of sample handling easier and faster, but \u2013 even more importantly \u2013 will enable users to do it remotely, from any place on Earth with internet connection. The robot mounts empty pins into CrystalDirect&#x2122; Harvester, then picks crystal-carrying pins up and stores them safely in vials filled with liquid nitrogen. It can even load and unload pucks automatically. The duo \u2013 CrystalDirect&#x2122; Harvester and MARVIN \u2013 will also allow non-expert users to prepare a large number of tricky and tiny protein crystals.<\/p>\n\n\n\n<p>\u201cLike for any other instrument we work on, this was a real team effort. From the very beginning, different members of our team contributed their expertise in robotics, electronics, mechanics, programming and cryogenics,\u201d said Mois\u00e9s Bueno, software engineer at EMBL Hamburg, who led the programming work on this project. \u201cIn addition, we integrated several elements developed by the <a href=\"https:\/\/www.embl.org\/groups\/grenoble-instrumentation\/\">Instrumentation Team at EMBL Grenoble<\/a>. The work was challenging because I had to learn many new things, such as image processing. But that was something I really wanted to learn, so it was fun.\u201d<\/p>\n\n\n\n<p>The Instrumentation Team works closely with EMBL Hamburg\u2019s beamline scientists, to make sure the instruments they build meet their needs. MARVIN, for instance, was tested by Saravanan Panneerselvam, Senior Technical Officer in the <a href=\"https:\/\/www.embl.org\/groups\/schneider\/\">Schneider Group<\/a>.<\/p>\n\n\n\n<p>\u201cWe are excited to use the robot with complicated and difficult to handle samples, such as crystals formed within living cells,\u201d said Panneerselvam. \u201cSuch samples can now be reliably harvested from CrystalDirect&#x2122; plates.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"A1\"><strong>Working as an engineer at EMBL<\/strong><\/h2>\n\n\n\n<p>Bueno has since moved to the European X-ray Free-Electron Laser Facility (<a href=\"https:\/\/www.embl.org\/about\/info\/arise\/european-xfel\/\">European XFEL<\/a>) to take up a new post as PLC Developer and Support Engineer. European XFEL has a long-standing cooperation with EMBL, including through <a href=\"https:\/\/www.eiroforum.org\/\">EIROforum<\/a>.<\/p>\n\n\n\n<p>\u201cFor me, EMBL has been an entrance to the scientific community,\u201d said Bueno. \u201cAs an engineer at EMBL, I had the opportunity to work with top notch technologies that in many other places you could only dream of. I also met very clever people from all over the world. All of this was a very enriching experience for me.\u201d<\/p>\n\n\n\n<p>The EMBL Hamburg\u2019s Instrumentation Team established their robotics lab a few years ago to enable projects such as MARVIN.<\/p>\n\n\n\n<p>\u201cThe new system is a prerequisite for users to prepare their crystals in the future with the harvester and without the need to travel to Hamburg.\u201d said Stefan Fiedler, the leader of the Instrumentation Team. \u201cWe will continue to develop our system in coordination with our colleagues in Grenoble. The MARVIN platform is quite universal so that we can add readily new functionalities and use it also for other applications, like X-ray microscopy for mounting sample on standard supports.\u201d<\/p>\n\n\n\n<p>The new instrument is in fact already the third MARVIN robot at EMBL Hamburg, the other two robots being in use at the <a href=\"https:\/\/www.embl.org\/groups\/macromolecular-crystallography\/beamline-p13\/\">beamlines P13<\/a> and <a href=\"https:\/\/www.embl.org\/groups\/macromolecular-crystallography\/beamline-p14\/\">P14<\/a>. There, they transfer thousands of pins per year loaded with crystals from storage containers directly onto a diffractometer, an instrument where the crystals are hit by an X-ray beam during an experiment. The measurements at the beamlines can be carried out remotely already, which was an important feature during the pandemic.<\/p>\n\n\n\n<figure class=\"vf-figure wp-block-image  | vf-figure--align vf-figure--align-inline-end  size-full is-resized\"><a href=\"https:\/\/www.embl.org\/news\/wp-content\/uploads\/2023\/02\/MARVIN-as-bee-at-Open-Day-Nov-2017-600x1000-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"vf-figure__image\" src=\"https:\/\/www.embl.org\/news\/wp-content\/uploads\/2023\/02\/MARVIN-as-bee-at-Open-Day-Nov-2017-600x1000-1.jpg\" alt=\"Yellow robotic arm disguised as a bee.

Credit: Stefan Fiedler\/EMBL<\/figcaption><\/figure>\n\n\n\n<p>Before it began operations, the robot was showcased to the public during an outreach event, <em>Hamburg Night of Science<\/em>. The engineers programmed the robot such that children and their parents could steer it to fish out hidden crystals and place them in front of a microscope. To get a better view, they could also make the robot rotate the sample. The effort paid off: MARVIN was greeted with a furore at the event, and the preparation was part of essential groundwork for getting the robot ready for its future tasks.<\/p>\n\n\n\n<p>\u201cThe activity for the night of science it is something that I am really proud of,\u201d said Bueno. \u201cI brought up the idea and we agreed to bring to the public something that combines instrumentation with crystallisation.
