Props in RoboCupJunior OnStage

Props in RoboCupJunior OnStage#

What are props? Props are objects used on stage to support or enhance a performance. In RoboCupJunior OnStage, props should only be used if they add clear value to the robotic performance.

Types of Props#

1. Interactive Props (Encouraged) Interactive props are objects that interact with robots or performers using sensors and/or actuators.

  • Must demonstrate active interaction (e.g. triggering sensors, responding to movement, controlling outputs)

  • Can include wearable items (e.g. gloves or costumes that communicate with robots)

  • Should contribute directly to the technical and creative elements of the performance

✅ Highly encouraged, as they enhance both innovation and robotics integration.

2. Static Props Static props are non-interactive objects used for decoration and “scene setting”.

  • Do not interact with robots or other props

  • Examples: cardboard scenery, painted backdrops, stage decorations

  • Can make it harder for judges and the audience to see the robots clearly

⚠️ static props should make a significant contribution to the overall performance.

Teams should:

  • Consider using the screen backdrop instead of large set pieces

  • Convert static props into interactive elements where possible

  • Minimise the number of purely decorative items

Good Practice for Using Props#

  • Focus on small, lightweight, and purposeful props.

  • Ensure props enhance the robotic performance, not distract from it

  • Props that do not add value are ignored in judging

  • Teams must be able to set up and remove all props without assistance

  • Use sustainable or recycled materials wherever possible

Examples of props good to be used during a performance include:

  • A wall that is used by a robot to show how it can avoid the wall. The wall is a static prop.

  • A door that opens when a robot gets close to it either by the robot sending a signal to the door to signal or the door has a sensor that detects the robot getting closer. The wall is an interactive prop as it uses sensors to interact with the robot.

  • A tree that receives a signal from the door (in the above example) and swings. The tree and door are interactive props.

  • A glove with a QR code (static prop) triggers an action on a robot when it scans the QR code.

🗝Key Message#

Quality over quantity: A small number of well-designed interactive props is far more effective than a stage filled with static decorations.
