Virtual Robots
HIL testing without the airframe: your controller stays in the loop, Virtual Robots plays the plant. Send motor commands over Zenoh, get the dynamics response back as states in real time, and pull camera frames into your perception stack over iceoryx2 shared memory. Nothing to crash, no field day lost. Community runs the moment you install it. Pro unlocks when you sign in with a course enrollment that includes it.

Virtual robots
Five vehicles, one control interface
Quadcopter and Truck are in Community. Helicopter, Global Hawk and Quad Bike unlock with Pro, along with every skin. Each robot's command set is documented in the SDK book.

Scenes
Six worlds to break your code in
Each scene is a testbed for a different class of problem: controller and estimator work, path search, waypoint navigation, thermal search, helipad operations. Sandbox, Flatworld and City ship with Community. Pro opens every scene.
SandboxEmpty ground for testing controllers and estimators.
FlatworldGrid world for 2D and 3D path search, including swarms.
CityStreets and buildings for waypoint driving and flight.
NeighborhoodHouses and yards for delivery and pickup runs.
ForestTree cover and terrain for thermal-camera search.
MountainElevation and helipads for helicopter operations.
Missions
Finish the mission
Autonomy is judged on the full loop: sense, navigate, act, done. Each scene carries missions with a defined objective, so your stack is measured on completing a job, not on open flight. Missions are Pro: every one of them, in every scene.

Interface
Two transports: Zenoh for control, iceoryx2 for vision
States, commands and parameter configuration travel over Zenoh. Camera frames take a different path: iceoryx2 zero-copy shared memory, so image publishing stays real-time instead of paying a serialization cost per frame. Image streams run at max game FPS on both tiers — what the plan changes is the Zenoh rates and the robot counts. Both transports are written up in the SDK book.
Transport · control planeZenoh
Pub/sub for robot states and command messages, plus a service for parameter configuration. Works across processes and across the network.
Transport · vision planeiceoryx2
Zero-copy shared memory for camera frames. Image streams publish at the game's own frame rate on both tiers, reaching your perception code on the same machine without a copy per frame.

Plans
Community and Pro
Pro arrives with a course enrollment that includes it. The unlock happens at sign-in — nothing to reinstall.
Heads upPro is not sold as a standalone membership — it comes with course enrollment only.See courses →

Questions
Do I need a different download for Pro?+
No. There is one app for both tiers. Sign in with an account that carries Pro and the app switches over.
What can I do without an account?+
Community mode runs the Quadcopter and Truck in Sandbox, Flatworld and City, with states and commands at 30 Hz and one image stream at max game FPS.
Where do I learn to drive the robots from code?+
The SDK book at ubicoders.github.io/vrobots-book covers installation, reading state, sending commands, cameras and services, with a reference chapter per robot. Same book for Community and Pro.
How does Pro reach my account?+
Through course enrollment. There is no standalone Pro membership on sale — enrolling in a course that includes Pro is the only way to get it right now.
Which operating systems are supported?+
Windows and Linux. Each build's card in the download section lists its minimum OS — the oldest version supported, not the only one it runs on.
Does Pro access expire?+
Not under the current policy. Pro comes with course enrollment, and enrollment is lifetime, so the unlock stays with your account and there is nothing to renew. That is how it stands today; the policy may change for future enrollments.
