OhhO Connect

One link: OmniBot and the simulator, over ROSBridge or serial.

Connect your browser to OmniBot or the simulator over ROSBridge (Wi-Fi) or Web Serial (USB) — with an in-browser simulator that runs with no install.

Overview (hero)

One link for OmniBot and simulation. OhhO Connect connects your browser to OmniBot and the simulator over ROSBridge (Wi-Fi) or Web Serial (USB). The in-browser sim (SimulatedTransport) runs with no install. Gazebo Harmonic is a ROSBridge you start (GazeboProvider, default ws://localhost:9090). Other robots are on the roadmap. BLE is an experimental browser transport; MQTT is roadmap. Isaac Sim and MuJoCo are not built. No SDK install, no Python, no robot-specific setup.

Highlights

  • Wi-Fi · ROSBridge WebSocket
  • USB · Web Serial (firmware-direct)
  • Bluetooth · BLE (Nordic UART): experimental, Chrome/Edge, needs NUS firmware on the robot; not tested on OmniBot
  • In-browser sim — no install (lib/connect/simulated.ts)
  • Gazebo Harmonic — a ROSBridge you start (lib/pilot/sim/gazebo.ts)
  • Isaac Sim — not built
  • MuJoCo — not built
  • Vision: not built — MQTT
  • OmniBot and simulation today — roadmap for other robots

What you get

  • Every robot speaks a different language on a different wire. A DDS-native humanoid talks DDS over Cyclone, a mecanum base speaks a serial protocol over USB, a drone speaks MAVLink, an industrial arm speaks Modbus. OhhO Connect is the layer that makes all of them look the same to every OhhO product.
  • Connect exposes a single transport interface — connect, send velocity, send joint commands, emergency stop, subscribe to telemetry — and implements it for each protocol. A console built against Connect works on a mecanum manipulator over Wi-Fi today and a humanoid over USB tomorrow, with zero code changes.
  • Because Connect runs in the browser, there's nothing to install on the operator's machine. Web Serial and Web Bluetooth are feature-detected at runtime. The in-browser simulator is SimulatedTransport and needs no install. Gazebo Harmonic is a ROSBridge WebSocket you start yourself; this site does not launch it. Isaac Sim and MuJoCo are not built.

Features

  • Transports in the console — ROSBridge WebSocket, Web Serial, Web Bluetooth, and a built-in simulator.
  • Vision: not built — MQTT for IoT and cloud fleets is not built.
  • Robot-agnostic by design — Connect speaks generic velocity and joint commands, not robot-specific SDK calls. A console built against Connect works on any robot with a transport implementation.
  • Browser-native, no install — Web Serial and Web Bluetooth run in Chromium browsers over a secure context — no driver install, no Python SDK, no desktop app. Open a URL and drive.
  • Mixed-content aware — Connect detects the HTTPS-to-ws mismatch and guides the operator to a secure rosbridge or a LAN connection, so the link just works instead of failing silently.
  • Persistent per-robot config — Each robot in the garage remembers its last protocol, address and baud rate — so reconnecting is one click, not a setup wizard every time.
  • In-browser sim, no install — SimulatedTransport integrates velocity into a pose in the browser. A deadman — pointer held on the stick, or Space — is required. Releasing it sends zero. E-stop latches until cleared. The console is /connect.
  • Gazebo is a ROSBridge you start — The Gazebo row opens its own ROSBridge WebSocket (default ws://localhost:9090) in GazeboProvider. ConnectConsole constructs that provider and calls connect. It publishes /cmd_vel only while the deadman is held and subscribes to /odom. A camera frame is shown only if /camera/front/image_raw (or a compressed image on that prefix) arrives. This site does not start Gazebo. Isaac Sim and MuJoCo are not built.

How it works

  1. Pick a robot — Select a robot from your OhhO Garage — Connect loads its saved transport settings.
  2. Choose a protocol — Connect shows the protocols available in your browser and on your robot — Wi-Fi, USB, BLE or Sim.
  3. Open the link — Connect establishes the transport, runs capability checks and streams live telemetry to every console.
  4. Operate — Every OhhO console reads the live connection and never needs to know which protocol is underneath.

There is no paid plan. The console demo is free. Hosted cloud is a waitlist, not a checkout.

FAQ

Do I need to install anything on my computer? No. Connect runs entirely in the browser. Web Serial and Web Bluetooth are built into Chromium browsers (Chrome, Edge) — no driver, no SDK, no desktop app.

Does Connect work with non-ROS robots? Yes. Web Serial talks the firmware protocol directly — no ROS needed. For DDS-native robots, pair Connect with OhhO Bridge to translate between DDS and ROS topics.

What if my browser doesn't support Web Serial? Connect feature-detects each protocol at runtime and shows only the ones your browser supports. Wi-Fi (ROSBridge) and the in-browser simulator work in any modern browser.

Does the in-browser simulator need an install? No. It is SimulatedTransport, and the teleop console is /connect. Hold the deadman to send velocity. Releasing it sends zero.

Does Connect run Gazebo, Isaac Sim, or MuJoCo? Gazebo Harmonic is a ROSBridge you start (default ws://localhost:9090). See GazeboProvider. Isaac Sim and MuJoCo are not built.
