An international collegiate robotic competition solely sponsored by DJI(Da-Jiang Innovations) every summer in Shenzhen, China.

During each 7-minute game, two teams of five players are to defeat the opponent robots by collecting and shooting marble bullets at each other. And of course, every robot is outfitted with a set of pressure-sensitive pads that can detect the impact of each bullet. Each year the competition arena is to be redesigned with new elements added in and competition rules modified in order to inspire the attendees to come up with more innovative designs on their robots.
