Can a greenhouse with a robotic arm feed astronauts?

Continuous human habitation of the Moon is the state aim of many major space-faring nations in the coming decades. Reaching that aim requires many tasks, but one of the most fundamental is feeding those humans. Shipping food consistently from Earth will likely be prohibitively expensive shortly, so DLR, Germany’s space agency, is working on an alternative. This semi-autonomous greenhouse can be used to at least partially feed the astronauts in residence on the Moon.
