RUBI (ROS_Utility_Board_Interface)

RUBI: A clean ROS 2 utility board showing live topic rates/delays, pub/sub nodes, services, actions, and system overview.

RUBI Banner

What is RUBI?

RUBI gives you a single, clean window to understand your ROS 2 robot at a glance:

  • Live topic publication rates & delays
  • Publisher & subscriber nodes per topic
  • All services with their server nodes
  • All actions with their server nodes
  • Full node list
  • Global search across everything
  • Freeze / Unfreeze updates

No heavy dependencies. Runs fast even on embedded systems.

Features

  • Realtime monitoring — rates & delays updated every ~0.4s from actual subscriptions
  • QoS friendly — uses BEST_EFFORT by default to avoid common incompatibility warnings
  • Multi-tab interface — Topics / Services / Actions / Nodes
  • Freeze mode — stop updates to read long node lists
  • Beautiful & minimal — Dear PyGui + clean layout

Installation

# 1. Source ROS 2
source /opt/ros/humble/setup.bash   # or iron, jazzy, etc.

# 2. Install Dear PyGui (only dependency)
pip install dearpygui

# 3. Clone & run
git clone https://github.com/ali-pahlevani/ROS_Utility_Board_Interface.git
