It is extremely important that a military robot be robust. Therefore, the latest machine to challenge the robot contest "Subterranean Challenge" [underground challenge] hosted by the U.S. Defense Advanced Research Projects Agency [DARPA] proves that it is robust.
競技 Driving robots into the underground, one of the harshest environments imaginable, is called “DARPA SubT,” with a familiar touch. The competition is aimed at promoting the development of next-generation military robots capable of moving around and mapping underground tunnels and caves. This approach is in line with the broader trend of developing robots for systems that can be deployed in hard-to-reach places, such as infrastructure inspection, disaster relief and mining.
は I recently joined the team "ExplorerI heard the members. One of the eleven teams participating in SubT is a joint team of Carnegie Mellon University and Oregon State University. The next competition is an exploration and rescue scenario in which a robot is sent deep into a nuclear power plant that has been left abandoned. Robots must search multiple floors and open spaces within the power plant to find multiple designated items, including backpacks, mobile phones, and survivors.

The Explorer team took the lead in the first competition "Tunnel Circuit" in August 2019. The difficulty with SubT, however, is that each competition is quite different.
Matt Travers, who led the team with Sebastian Scherer, said: "Exploring multiple spaces on multiple floors requires new equipment and search tactics. In the previous tunnel exploration, all designated items were close to the path that the robot would move around. , It will be more difficult to find items. ''
Stairs are also a big issue.
"Stairs are a very difficult task for wheeled vehicles," said Travers. He is a systems scientist at the Robotics Laboratory at Carnegie Mellon University.
Explorer team robots operate 500 pound [about 227 kg] vehicle robots. Climbing up and down stairs with this robot is very difficult and complicated. So the team added a third car, half the weight and the same power, to allow for stair climbing.
The Explorer team also operates drones designed to fly in tight spaces.
"The drone was designed from the ground up to fly indoors," said Scherer, an associate research professor at the Robotics Laboratory. The rotors, typically located at the top of the four corners of the drone, were lowered and brought closer together, reducing the width to just 26 inches.
Drones are also equipped with bumpers. The drone runs out of battery sooner than the vehicle, so you will have to wait behind the vehicle robot until it comes.
