THE INSTITUTE Teenager Ari Firester watched on television last year as members of a youth soccer team were saved from a flooded cave in Chiang Rai Province, Thailand. The two-week-long effort, which left one rescuer dead, inspired Firester to create a technology that might prevent such a tragedy from occurring again.
THE INSTITUTE Teenager Ari Firester watched on television last year as members of a youth soccer team were saved from a flooded cave in Chiang Rai Province, Thailand. The two-week-long effort, which left one rescuer dead, inspired Firester to create a technology that might prevent such a tragedy from occurring again.Firester, 16, a junior at Hunter College High School in New York City, created “Wormbot,” an earthworm-inspired robot capable of maneuvering in narrow spaces. The project was displayed at Intel’s annual International Science and Engineering Fair, held in May in Phoenix. His invention earned him the US $10,000 IEEE Presidents’ Scholarship, which is given at the fair.
Controlled by an Arduino microcontroller and built with off-the-shelf items, the robot makes wormlike movements by using eight retractable claws along its length to grip its surroundings and prevent it from slipping. The modular robot is powered by compressed air. The control and power components are connected to the robot through a thin, plastic air tube. By using inflatable actuators, its body can be lengthened, shortened, or bent.
