What indicates a robot is fully returned to its Base?

The indication that a robot is fully returned to its Base is when all its support comes from the Base zone tiles. This means that the robot must be entirely on the designated tiles that are defined as the Base zone. This is important because it ensures that the robot has completely left the playing field and is fully situated within its home area, which is a common requirement in many robotics competitions.

When a robot is fully on the Base zone tiles, it can be clearly verified that it has completed any necessary tasks related to its position on the field, including safely returning to its designated area after completing its objectives. This condition aligns with scoring rules and gameplay strategies that emphasize the importance of the separation of zones and safe placement within defined areas on the field.

In contrast, other options suggest varying degrees of proximity or overlap with the field, which do not provide a definitive indication of a robot fully returning to its Base. For instance, being near the Base zone or having partial support from the field indicates that the robot is not entirely in its designated area. Scoring points in the Base zone is also unrelated to the specific physical positioning of the robot regarding being fully returned to the Base.
