The robot should be switched to manual control automatically after it completes automatic zone.

A white line denotes the switch between the automatic and manual zone.

Robot has to indicate this by switching ON the LED on the robot.

In case of failure to turn ON the LED, the participant will be allowed to use remote after 20 seconds(can switch robot to next zone manually as well).

The wireless device(remote) should be kept in manual zone till it crosses automatic zone from the start of play.

The fastest robot to reach the final point in specified time (3 min) will be declared winner.

If both robots fail to reach the final point in specified time (3 min), the robot nearest to the final point will be declared winner.
