The RoboCup Small Size League (SSL) is one of the RoboCup soccer leagues.
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. The field size is 9metersx6meters. 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.
As of 2018, there are now two divisions, the B division that continued to use the same parameters as before (6 robots, 9x6 meter field, etc) and the A division that changed a lot of parameters. 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.
