Robotic Snake Removes Toxic Metals From Water

 A robot concept that can remove toxic metals from water has been recently developed by a group of designers from the Fortune Institute of Technology. The robotic snake has bacteria (Shewanella oneidensis) inside that disintegrate harmful heavy metals polluting water.
Moreover these bacteria also generate electricity to power the robot snake, thus allowing it to swim around. Users can easily locate the robot due to the built-in GPS. The robotic snake lights up with red LEDs when it is working and with green LEDs when it has finished cleaning. Designers hope that the heavy metal pollution cleaning system will be launched in 2020.
