Blue Owl

Blue Owl provides Technical Official device integration for owlcms via a microcontroller powered by Johnny-Five.

Overview

Referees

Referee control boxes may be used in compliance with the IWF Referee Light System as documented in TCRR 3.3.6. The referee control boxes support:

• White and red buttons for "Good lift" and "No lift".
• White and red LEDs to confirm decision entry.
• LED, buzzer, and vibration to signal when a decision is required.
• LED, buzzer, and vibration to signal when summoned to the jury table.

Single Referee Mode

For competitions run with only one referee, simply configure all three referees with the same buttons. This will cause the single referee control box to send a decision for all three referees.

Down Signal

The down signal box may be used in compliance with the IWF Referee Lifht System as documented in TCRR 3.3.6.5. The down signal box supports:

• Visible signal via a relay.
• Audible signal via a relay.

Timekeeper

The timekeeper control box may be used to fully control the timing clock as documented in TCRR 7.10. The timekeeper control box supports:

• Starting the clock.
• Stopping the clock.
• Resetting the clock to one minute.
• Resetting the clock to two minutes.

Jury

The jury control panel and jury control units may be used to fulfill all jury member requiremensts as documented in TCRR 3.3.6.11, TCRR 3.3.6.12, and TCRR 7.5. The jury control panel supports:

• Displaying referee decisions in real time.
• Displaying jury member decisions.
• Summoning a referee.
• Summoning the technical controller.
• Stopping the competition for deliberation.
• Stopping the competition for a technical break.
• Resuming the compeition.

API

Each technical official is represented by a model, e.g., Referee. These models provide the logic and APIs necessary for the official, but do not provide any hardware-specific implementations. Instead, the models provide methods for actions that the official can perform and emits events for information provided by owlcms. Each model must be instantiated with a set of modules which provide the hardware-specific implementations.

Types

The documentation uses a few custom types:

Color

The strings aqua, cyan, fuchsia, lime, magenta, white, and yellow.

Decision

The strings bad and good.

JuryMemberDecision

The strings bad, good, and hidden.

JuryMemberNumber

The numbers 1, 2, 3, 4, and 5.

RefereeNumber

The numbers 1, 2, and 3.

Owlcms

The Owlcms class provides the necessary APIs for two way communication between the models and owlcms. Unless you are building a custom integration with owlcms that does not use the provided models, the API provided by Owlcms will not be used directly.
