Two teams of six robots which are limited to an 18 cm diameter and 15 cm height play soccer with an orange golf ball.
They are identified and tracked by four overhead cameras connected to an off-field computer.
Then robots' and balls' status including their position and id are sent to teams' computers.
Their AI software sends commands to the robots based on the vision data.
This change was brought to improve the tournament experience by making the more experienced teams face each other while letting the newer teams improve their algorithms with more balanced face offs.
