Humanoid robots could be used to stretch and strain bioengineered tissues, providing them a suitable environment for growth:

Right now, tissue engineering relies on bioreactors to grow sheets of cells. These machines often look like large fish tanks, filled with a rich soup of nutrients and chemicals that cells need to grow on a specialized trellis. The problem, explain Mouthuy and Carr, is that bioreactors currently "fail to mimic the real mechanical environment for cells." In other words, human cells in muscles and tendons grow while being stretched and moved around on our skeletons. Without experiencing these natural stresses, the tissue grafts produced by researchers often have a broad range of structural problems and low cell counts.

That's where robots come in. The researchers propose a "humanoid-bioreactor system" with "structures, dimensions, and mechanics similar to those of the human body." As the robot interacted with its environment, tissues growing on its body would receive the typical strains and twists that they would if they grew on an actual human. The result would be healthy tissue, grown for the exact area on the body it was destined to replace. Mouthuy and Carr note that this would be especially helpful for "bone-tendon-muscle grafts... because failure during healing often occurs at the interface between tissues."

What would this humanoid-bioreactor system look like? It could possibly be built on top of a humanoid robot with "soft robotics" muscles made from electroactive polymers, and the growing muscles could piggyback on those to get their exercise. It would also need to be covered in soft, stretchable sensors to monitor the health of the growing tissues.

Nvidia Announces “Moonshot” to Create Embodied Human-Level AI in Robot Form 16 comments

In sci-fi films, the rise of humanlike artificial intelligence often comes hand in hand with a physical platform, such as an android or robot. While the most advanced AI language models so far seem mostly like disembodied voices echoing from an anonymous data center, they might not remain that way for long. Some companies like Google, Figure, Microsoft, Tesla, Boston Dynamics, and others are working toward giving AI models a body. This is called "embodiment," and AI chipmaker Nvidia wants to accelerate the process.

[...] To that end, Nvidia announced Project GR00T, a general-purpose foundation model for humanoid robots. As a type of AI model itself, Nvidia hopes GR00T (which stands for "Generalist Robot 00 Technology" but sounds a lot like a famous Marvel character) will serve as an AI mind for robots, enabling them to learn skills and solve various tasks on the fly. In a tweet, Nvidia researcher Linxi "Jim" Fan called the project "our moonshot to solve embodied AGI in the physical world."

[...] According to Fan, Project GR00T is a cornerstone of his newly founded GEAR Lab (short for "Generalist Embodied Agent Research"). During his time at Nvidia, Fan has specialized in using simulations of physical worlds to train AI models, and now that approach is extending to robotics. "At GEAR, we are building generally capable agents that learn to act skillfully in many worlds, virtual and real," wrote Fan in a tweet. "Join us on the journey to land on the moon."

    We already use babies/adolescents for this purpose: They provide a nice scaffolding for highly sophisticated tissue, which is then forcibly cut away from their sexual organs and sold as "harvested foreskin tissue" for the purposes of skin grafts and cosmetic research.

      Except the flesh grafted onto Data likely came from another crew member, and not grown in a vat.

    It's like some people are actively trying to create the terminator robot, do these people watch dystopian science fiction and miss the fact that these ideas usually have terribly bad outcomes for most of humanity.

      Considering the way humanity acts all by itself, I'm not sure that having a bunch of killer machines trying to exterminate them is such a bad thing. In the machines' view, they're valiantly working to contain and neutralize a dangerous threat to the rest of the universe.

      Besides, it could be really useful having my own personal Terminator.
