Real Human Tissue

With all the advances being made in robotics in terms of capabilities, it was only a matter of time before researchers took it one step further, making robots look more human.Thats what a pair of biomedical researchers at the University of Oxford are hoping to do, anyway.

In a report published in Science Robotics,Pierre-Alexis Mouthuyand Andrew Carr assert that the time has come to beginbuilding robots with real human tissue. Not just for looks, either: using humanoid robots would be ideal for advancing our understanding of muscle and tendon grafts, and refining the technologyused to develop them.

To engineer tissue, scientists use bioreactors filled with nutrients and chemicals that can grow sheets of cells. Cells in muscles and tendons, however, require the ability to be stretched and moved by the skeleton a mechanical component that bioreactors are unable to mimic.

Because humanoid robots are capable of mimicking human movement, they would prove an excellent tool. They can essentially serve as a humanoid-bioreactor system, and the tissuecould develop with a little structural help from the robots, more or less the same way it would on a human skeleton.

The ability of humanoids to freely interact with their environment and real objects could be an advantage compared with desktop bioreactors. This may provide more realistic stresses to tissue constructs and eventually achieve grafts with better functionality or with tailored properties, Mouthuy and Carr explain in Science Robotics.

In theory, a humanoid-bioreactor system can be built on top of the humanoid robot using muscles made with electroactive polymers. The developing muscles can essentially piggyback on the robot skeletons movement so the tissues get exercised.The robot skeleton wouldneed to be covered in soft, stretchable sensors so that it can closely monitor the development of the tissues.

In their research, Mouthuy and Carradd that [] in aging populations, musculoskeletal tissue disorders and injuries are a growing health, social, and economic burden. Pain and lack of mobility are common problems due to failure of tissues, such as tendon, ligament, bone, and cartilage. A promising repair strategy is to engineer tissue grafts.

This will lead to the creation of more clinically relevant musculoskeletal tissue grafts and, in particular, allow for personalized tissue graft development by matching the robots morphology and mechanics to the patients needs.

Following this method, its likely we will likely end up with a robot that looks like the Kenshiro robot developed in Tokyo, where its actuators closely copy human movements. In other words, a Terminator-like humanoid robot where a metal skeleton would be covered in human muscles, tendons, and skin.

The researchers assert that not only do we have the technology to make this happen, but that it likely will. Given that it would bescientifically relevant,and has numerous applications in regenerative medicine and other fields, it looks like we could be mingling with robot lookalikes sooner rather than later.
