The European Space Agency\u2019s Argonaut<\/a> landers will bring up to 1500 kg of cargo to the Moon. Ranging from rovers and science instruments to building blocks for lunar infrastructure, the weighty goods will need to be offloaded from the lander onto the lunar surface.<\/p>\n

Some cargo, like sensitive science instruments, will need to be placed metres away from the lander for uninterrupted measurements, far beyond the reach of robotic arms.<\/p>\n

Romanian research institute COMOTI<\/a>, together with Initium Space<\/a>, developed a specialised lunar crane that can lift up to 1000 kg of cargo off a lunar lander like Argonaut and place it up to six metres away. The project, called Loader, is supported by ESA\u2019s Technology Development Element<\/a>.<\/p>\n

A scaled model of the crane was tested in ESA\u2019s Planetary Robotics Laboratory<\/a> in the Netherlands. Watch it move a payload mock-up around the lab.<\/a><\/p>\n

\u201cThis scaled model is only able to lift 30 kg under Earth gravity, equivalent to a little over 180 kg on the Moon, but it allows us to test the functionality and accuracy of the device in a lab environment,\u201d comments Gunter Just, ESA\u2019s robotics engineer. \u201cUltimately, the crane will be more than twice as big, and with the Moon\u2019s gravity being six times weaker than on Earth, it will be able to lift up to a tonne of material.\u201d<\/p>\n

Daniel Useriu from COMOTI explains: \u201cThe crane will be launched in a folded configuration on the lander\u2019s payload deck and will deploy once it reaches the lunar surface. A dedicated cable-management system and a carefully defined unfolding sequence ensure that the crane is very compact when stowed while still easy to control and deploy.\u201d<\/p>\n

A special levelling system keeps the crane vertical even if the lander comes to rest on sloped terrain. Above the base, a long arm connected by two joints ends in a set of grippers \u2013 a passive, spring-loaded one that can lock into place without power, and a battery-powered one that can rotate the load for more precise positioning.<\/p>\n

\u201cI am very proud of what the COMOTI team, in collaboration with Initium Space, has achieved with this demonstrator,\u201d concludes Daniel. \u201cWe have successfully met, and in some areas exceeded, our initial expectations. There is still a great deal of work ahead to refine the crane, but this demonstrator gives us a strong foundation for the next steps.\u201d<\/p>\n
