  • John Hopkins University scientists of USA have built a soft robot named Gelbots.
  • Gelbots are made out of gelatin.
  • They are created by 3D printing.
  • They are capable of moving without requiring an extra power source because of the way their shape, dimensions and patterning of gel are designed.
  • This is because the gels swell or shrink in response to temperature.
  • They can be used to create smart structures.
  • Even they can be used for moving on surfaces through the human body to deliver targeted medicines.
  • They could also be deployed as marine robots, patrolling and monitoring the ocean’s surface.
  • Gelbots can be trained to crawl in response to variations in human biomarkers and biochemical.
