Redwire, in collaboration with Added Value Solutions and with support from the European Space Agency (ESA), has successfully developed, tested and delivered its prototype of a lunar robotic arm: the Manipulator for Argonaut Payload Needs and Unloading Support (MANUS). The project is being led by Redwire’s Luxembourg team, which recently completed several project milestones including preliminary design and performance assessment.
Before successful delivery, the MANUS Breadboard Model underwent a comprehensive test campaign to verify the functionality and performance of the manipulator and tool-changer subsystems, and to demonstrate operational scenarios aligned with system requirements. All planned operations, including payload handling, end-effector actuation with wireless data and power transfer, range extender manipulation and automatic deployment, were executed successfully, confirming overall system readiness. Functional testing validated safe and reliable mechanical performance, demonstrating strong joint-space accuracy and stable interaction among subsystems.
MANUS is designed to support the loading and unloading of equipment and cargo from ESA’s Argonaut lander, which will enable Europe to deliver 1500–1800 kg of cargo, infrastructure and scientific instruments to the lunar surface. The manipulator could facilitate loading and offloading to a rover, directly onto the lunar surface or to an astronaut.
MANUS could also function as a connector for rovers to transfer power and charge batteries, as well as a tool to scoop lunar regolith. The Argonaut program aims to establish an enduring European presence on the Moon and ensure that Europe remains a leading participant in global space exploration.
