Research
Korean researchers have developed a beetle-like soft robot, part of a broader wave of robotic animals that researchers argue can demonstrate genuine practical value rather than serving as novelty gadgets. The work, highlighted by the Korea Advanced Institute of Science and Technology (KAIST), points to how biologically inspired machines are being engineered to solve real-world problems.
The term “robotic animals” covers more than battery-powered toys. These are complex electronic devices infused with elements of artificial intelligence that replicate the appearance and behavior of real or imaginary creatures. They contain sensors, speakers, motors, and processor modules that analyze external signals, and they are controlled via mobile apps. Digital pets can make distinctive sounds, respond to signs of affection, answer to their names, and display emotions ranging from delight to fear, satisfaction to fatigue. Manufacturers take a variety of engineering approaches when building them.
Leading research centers such as the Korea Advanced Institute of Science and Technology (KAIST) are working on developing similar insects, and the answer to why lies in solving practical and even humanitarian problems.
Among the examples is the microrobot beetle, which may look like a small gadget but reflects serious research at leading centers such as KAIST, which is developing similar insects. The motivation behind robot ants, robot beetles, and robot bees is to address practical and humanitarian challenges.
One such application is search and rescue. In spring 2022, a six-story building collapsed in Changsha, China, trapping dozens of people under the rubble. Many remained missing for nearly six days as rescue efforts were hampered by piles of debris and collapsed floors. Ultimately, 53 people died and only 10 were rescued. In such operations every minute is precious; rescuers use thermal imaging cameras and comb through the rubble, but this takes time. The article raises the prospect of cockroaches coming to the rescue, noting these insects are fast and can penetrate spaces that are difficult for conventional tools to reach.
The source does not detail specific performance metrics, payloads, control methods, or publication venues for the KAIST insect robots, so quantitative evaluation of these platforms remains to be reported.
