Off The Grid

The game field represents a damaged electrical grid that needs repair.  The field includes a diagonal row of high voltage towers where 345KV power lines need to be installed to complete multiple circuits.  On the center tower there are poles where 138KV power lines need to be installed to bridge between the high voltage transmission lines and other areas of the grid.  Large square substation transformers are needed near the edge towers for the high voltage line and near the 138KV poles.  Conduit is to be installed in underground trenches (surrounded by ramps) that allows the connection of 13KV circuits to the periphery of the field.  Distribution power poles near houses along the edge of the field provide support for 4KV power lines.  The installation of cylindrical residential transformers is also needed on the power poles near the houses.  In addition to installing and repairing the grid components there is debris cluttering the area that needs to be removed. As a new twist to this year’s game robots are also tasked with autonomously delivering spare insulators from the starting area to one or more of the high-voltage towers.



Most scoring areas are shared and are accessible by all teams on a first-come basis. Only the following scoring areas are assigned to a specific team:
To allow proper identification of which team scored in the common scoring areas many of the team-assigned game pieces are color coded to match the team.  A summary of the shared and team-assigned game pieces is contained in the table that follows that also details the initial location of the game pieces.

Other than autonomous delivery parts (discussed later) scoring is based on the position of the item at the end of the match. The 345KV and 4KV lines are scored based on the number of segments that have been properly installed where a segment is supported by two hooks/insulators. The 138KV lines are scored per connection made but the second connection must be to the corresponding spot on the opposite pole. Conduit must lay flat within a trench to score.  Transformers are scored by either being properly installed in the base pad or mounted to the residential pole depending on the type of transformer. Ground debris can be scored by placing it into the staging area or into the debris bin.  Point values for the various scoring actions are detailed in the table that follows.

Autonomous scoring can happen at any point during a match.  Although black and white roads are provided to help robots find their way to the scoring towers, robots are not required to follow the lines.  The sequence required for a robot to make an autonomous delivery attempt is summarized as:
  1. The robot (flag) is located in starting box, and the driver notifies the referee that the team intends to attempt an autonomous delivery.
  2. The driver places joystick on the transmitter shelf.
  3. One (and only one) spare insulator is loaded onto the robot by the lineman (spotter).
  4. The driver initiates an automatic operation (without lifting the joystick) that causes the robot to operate without human interaction.
  5. To score, the insulator must not be touching robot and must break the plane of the base of the tower (and remain) prior to the end of the autonomous operation and the end of the match.
  6. The autonomous period ends when the driver touches the joystick again.
The following bonus score opportunities exist in addition to the scoring elements previously described:
  1. Connecting one segment of any power line.
  2. Filling one conduit trench (three pipes).
  3. Installing one substation transformer.
  4. Placing one debris item into the dumpster.

There are many additional rules governing the actions of the team members on the field, but a few important restrictions are as follows. 
Teams have constructed their machines subject to a list of allowable materials and other rules on construction, as well as initial size and weight limits.  There are also numerous restrictions on how the game is played.  A partial list of restrictions includes:
There will be three phases to the contest: a partial round robin seeding competition, a six-game round robin semi-final between the top 16 teams, and a three-game round robin final between the top four teams.  During the seeding competition, each team will play eight games against randomly selected opponents.  The team’s average score (after the lowest score is dropped) during the seeding competition will be used to rank the team and to determine 14 of the 16 teams that will advance to the semi-final round robin playoff.

The 15th and 16th teams for the semi-finals will be the highest scoring teams during two “wildcard” games. The participants for the wildcard game are selected based on the score of their engineering notebook.  All teams are required to turn in an engineering notebook documenting the development and design of their robot.  This notebook is a significant portion of the BEST Award and the wildcard game gives teams further incentive to turn in quality notebooks by rewarding them for their effort.

At the start of the semi-finals, the scores will be reset to zero. For the semi-final round robin playoff, the top 16 teams will each play three matches.  The total of each team’s scores for these three matches will determine which four teams advance to the finals.  For the final competition, total scores will again be reset to zero.  The top four teams will play three additional matches to determine the final ranking order.
