Google and NASA Are Building a Robot Medical Assistant for Deep-Space Missions
Google and NASA are developing a robotic medical assistant for deep-space missions. Here is what it can do, how it was tested, and how early the project is.
Updated November 2, 2026
Google and NASA are developing a robotic medical assistant for astronauts on future deep-space missions. Headlines call it a "robot doctor," but the project is more modest: a robot meant to help a human crew medical officer with medical tasks, cargo handling and routine maintenance. It is also still an early proof of concept.
What was announced
Jim Kelly, vice president of federal at Google Public Sector, described the project in a blog post. Google is working with NASA's Human Research Program, the robotics team at Johnson Space Center, and the Jet Propulsion Laboratory (JPL). The work is aimed at future deep-space missions under NASA's Artemis program and beyond.
How it would work
- A helper, not a doctor. The robot works under the direction of a human crew medical officer, who keeps authority over diagnosis and treatment.
- Plain-language commands. Astronauts would direct it with plain-English instructions, by text or voice.
- Medical tasks. In one example Google gave, the robot could retrieve and prepare an ultrasound machine so a crew medical officer can perform a scan. The long-term goal includes helping with routine health monitoring, such as capturing basic vitals.
- Navigation. Google is adapting navigation technology developed at JPL to help the robot move around and find equipment.
Built on an earlier AI project
The robot grows out of the Crew Medical Officer Digital Assistant (CMO-DA), an AI medical decision-support system that Google and NASA have been developing and testing since 2025. CMO-DA is software that helps astronauts assess symptoms when talking to doctors on Earth is delayed or impossible. The new project adds a physical body to that idea.
How far along is it?
Not far, and the reports are clear about that. Google used DeepMind's MuJoCo physics simulator to test the robot's movements. In initial lab trials, the system located and moved a medical bag in 85% of attempts. That is a promising early result for a basic task, but it is not evidence the robot is ready to assist with medical procedures. Coverage notes that Google has not produced a finished, space-ready robot, and that microgravity changes how robot arms move and how fluids behave.
Why NASA wants this
On the Moon and especially on the way to Mars, a doctor on the ground cannot supervise in real time because of communication delays. Crews need to be able to handle emergencies on their own. A robot that fetches equipment, holds things and handles routine tasks could free the crew's medical officer to focus on the patient.
Where Artemis stands
The work supports the Artemis program, which completed its first crewed flight around the Moon with Artemis II in April 2026. NASA plans an Artemis III demonstration in low Earth orbit in 2027 and its first crewed Artemis Moon landing in 2028. It is also planning a Moon Base near the lunar South Pole.
What to watch next
- Whether lab results move beyond fetching objects to supervised medical tasks.
- Testing in microgravity or space-like conditions.
- How medical decision-support software and the robot are combined, and how safety is validated.
