The future is here. Robots here and there and there are invisible.
Engineers from the Massachusetts Institute of Technology (MIT) developed a robot entirely made of hydrogel – a transparent rubbery substance primarily made of water. However, the robot made is strong enough to capture and release swimming live fish.
Movements of this robot is possible through pumping water on its hollow tubes. Pumping makes the hydrogel stretch and contract.
Water property of the hydrogel allows it to share the same qualities of water. It the hydrogel is underwater, it goes invisible. What this video for more information:
The team of engineers is led by Xuanhe Zhao, associate professor of mechanical engineering and civil and environmental engineering at MIT, and Hyunwoo Yuk, a graduate student who hopes to use hydrogen robots in medicine.
Going back to the hydrogel robot, experiments have shown that the robot can hold the live goldfish up to a thousand times without rupturing it. The robot can also camouflage even with different colored background.
Each robot are made of 3-D printed cubes and laser cutting techniques interlocked with each other. The pumping of the syringe creates a sudden strong motion.
Much of the possible implication of this technology will be on the field of medicine. Both Zhao and Yuk believes that hydrogel is a perfect material that can potentially replace body organs. The researchers are now cooperating with medical doctors. Imagine in the future where hydrogel hearts can be made. Looking for organ donors will be easier and cheaper. Thus, this technology can save a lot of lives.
I wonder if this tech can create camouflage naval weapons.
