Brazil to Use Robots for Security at World Cup
February 21, 2014
Thirty “PackBots” will be provided by Massachusetts-based iRobot to the Brazilian government in a $7.2 million deal for the FIFA World Cup.
According to Robohub, it is expected that the 12 host cities will share the high-tech machines to help boost security and examine any suspicious packages. The PackBot has been used previously in military zones, where soldiers use them to cross minefields and clear buildings.
