NOUNScientists have been trying to build snakelike, limbless PLURAL NOUN robots for decades. These robots could come in handy in search-and-rescue situations, where they could navigate ADJECTIVE collapsed buildings to find and assist PLURAL NOUN survivors.
With slender, ADJECTIVE flexible bodies, limbless robots could readily move through ADJECTIVE confined and cluttered spaces such as debris fields, where walking or ADJECTIVE wheeled robots and human rescuers tend to fail.
However, even the most ADJECTIVE advanced limbless robots have not come close to moving with the agility and versatility of worms and snakes in difficult terrain. Even the tiny nematode NOUNworm Caenorhabditis elegans, which has a relatively simple nervous systems, can navigate through difficult physical environments.
