The Dutch team Tech United played in the world championship final against the Iranian team MRL. The robots from Tech United, equipped with EtherCAT, led 2-1 at the break. In the second half, Tech United extended their lead to 4:1 for a comfortable victory.
Six players make up a team in the Middle Size League, the largest and fastest class in the RoboCup competition: the maximum speed is around 4 m/s. Each of the three-wheel robots weighs about 35 kg and operates completely autonomously and without remote control. Communication between the robots takes place over wireless Ethernet. Visual orientation takes place using a camera directed vertically upward. This looks at a parabolic mirror and ultimately obtains a 360° picture of the environment. The individual robots can perform different functions in the game, such as the position of defender, striker or goalkeeper.
The automation components for the Tech United robots were sponsored by Beckhoff and IAL, the Dutch Beckhoff distributor: EtherCAT as the interface for the drives, sensors and actuators, plus an Industrial PC from the C6920-0010 series.
