Two British scientists have gone the Infocult route in recommending a new way to handle artificially grown human tissue. They recommend attaching the new meat to robots, so the machines can work it into flexibility.
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. The result might look a bit like the University of Tokyo's Kenshiro robot, whose actuators make realistically human movements. Its body would be covered in squishy, fluid-filled bags of engineered tissue. Patients needing tendon replacements in their hands might be able to shake hands or play piano with a robot who is wearing their future tendon grafts.
Annalee Newitz concludes:
Looking to the future, Mouthuy and Carr suggest that this could be the first step toward "biohybrid humanoids" with "cell-based actuators." In other words, this robot would be like the Terminator, whose metal endoskeleton is covered in human muscles, tendons, and skin. Obviously, if we want to create truly humanoid robots, it would make sense to eventually create ones whose musculoskeletal systems are made from cellular tissue rather than stretchy polymers. After all, this tissue is self-repairing and perfectly designed to stretch and contract.
