Space and astronomy news
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.
But as any gardener would tell you, greenhouses are a lot of work. And any time an astronaut spends on greenhouse maintenance is time they can’t spend doing other tasks, like scientific research. So, it would be extremely beneficial if there was a robot to assist with greenhouse operations, even if that robot had to be remotely controlled by an operator back on Earth.Enter EVE, which consists of three main components.
The robotic arm is based on DLR’s “This Is Not an Arm” project. It has seven degrees of freedom, which allows for precise positioning of its end effector. Each of its three joints has around three electronic controllers for motor control, power management, and communication. It’s supported by a camera system that senses its surroundings and allows remote operators to tell where the end effector is positioned.
