The Droid Vision app allows robot enthusiasts to experience the world from a mobile robot's perspective.

Step-by-Step Tutorial: https://www.modularmachines.ai/droid_vision/2024/11/24/DroidVision-Tutorial.html https://www.modularmachines.ai/droid_vision/2024/11/19/DroidVision-RC.html https://www.modularmachines.ai/droid_vision/2025/03/06/DroidVision-Teleop.html https://www.modularmachines.ai/droid_vision/2025/07/07/Video-Streaming-Server.html The app uses the RTSP streaming protocol to display real-time video streams. It has limited free streaming to try out. You can buy the "Unlimited Streaming" feature to remove the time limitation. Additionally, you can purchase add-ons to record video and connect multiple robot cameras to the app.
