Robot Substitution

Definition

Robots are substituted by the robot handler of the respective team. No other team member is allowed to take robots out or put robots in.

The robot handler should prefer to use long sleeves and colors that won’t interfere with the vision system.

Robots can always be taken in and out during game play without notifying the referee if all the following conditions are met:

  1. The robot is at least partially inside the field margin.

  2. The robot is at a distance from the halfway line that must not exceed 1 meter.

  3. The ball must be at least 0.5 meters away from the robot.

Additionally, robots can be taken out from any position on request using the procedure below:

  1. The robot handler requests robot substitution at any time.

  2. The game controller will halt the game at the next opportunity.

  3. The robot handler may enter the field and touch robots now.

  4. The robot handler takes robots out.

  5. The robot handler informs the referee when done.

  6. When both teams finished the robot substitution, the referee informs the game controller operator.

  7. The game controller operator performs a stop followed by continuing the game.

The maximum allowed number of robots of the team on the field must not be exceeded at any time when putting robots in.

Usage

Robots can be substituted for any reason. A substitution grants the team 20 seconds to take robots out. After that time, a new substitution is started. Each team has 5 free substitutions per halftime. Every additional substitution will result in an excessive robot substitutions foul for the team.

A robot substitution intent can be made by:

  1. A robot handler by informing the game controller operator who in turn enters the intent into the game controller.

  2. A robot handler by using the remote control, if provided.

  3. A team software by sending a request to the game controller.

  4. The game controller itself if a team exceeds the maximum number of robots (for example after a team receives a yellow or red card).

If the game was halted due to a substitution intent by a team, at least one robot must be taken out by this team. A substitution intent can be revoked unless the game was not already halted for substitution.

If a robot substitution intent for either team is present just before the game would continue after ball placement, the game controller automatically halts the game.
