Rob, I agree. The field of robotics is constantly changing. The days of mechanized machines are becoming quite eloquent and sophisticated using bioengineering as the catalyst in the design process. Although I'm not an advocate of creating artifical beings, the ability to create robots with human dexterity is somewhat intriguing. As always, great article Ann!

This is fascinating stuff, Ann. I find it amazing that muscle tissue is the engeineering answer to moving a robot. You're covering a very exciting field.

Rob, if you mean the use of animal tissue to create genetically engineered tissue, that practice is pretty regular. So are the protests by PETA et al. But this story is all about robots, not using this stuff on humans.

Here's an icky answer for how genetically engineered tissue is kept alive. First, just from being a sci-fi fan I knew the tissue had to be grown and preserved in some kind of artificial, nutrient-rich medium. This article on creating artificial meat (hence the "ick" factor) has some answers on how that's done:

But does that mean that skeletal muscle tissue on a robot is somehow immersed in a liquid nutrient bath?

Wow. I would imagine that brings up bio-ethical issues, Ann. Very Matrix.

I'm pretty sure it's the same thing that keeps me alive... Pepsi.  I think I could see the hose in the viedo.  (just kidding).

gsmith, there was no indication yet about the team's future plans for robots, or using this skeletal muscle tissue in humans. Use in humans would be an entirely different bioengineering project.

Rob, you're asking the same excellent question Jack asked regarding the engineered tissue in the Medusoid. As I responded to him, I think the answer lies more in the realm of biotech than robotics, at least for now. Does anyone else know?

I agree pretty incredible.   Ann, any idea when MIT and U of PA plan to have the first working model of their genetically engineered robot?  Are there plans on using the engineered skeletal muscles in humans?

Great story, Ann. If these are genetically engineered muscles, then it sounds like they're alive. If so, what keeps them alive? Or, is this material artificial?

Thanksgiving is a time for family. A time for togetherness. A time for… tech?
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
Researchers have developed a new flexible fabric that integrates both movement and sensors, introducing new potential for technology-embedded clothing and soft robots.
Made by Monkeys highlights products that somehow slipped by the QC cops.
