Just install Husarnet Client on your laptop and robot, connect them to the same Husarnet network, by using an online dashboard and enjoy low-latency connection between your devices :) All traffic is encrypted using ephemeral keys, and it works with ROS out of the box. Husarnet is an open source peer-to-peer VPN - that means you can connect your robots directly over the Internet, with no central VPN server for data exchange.

switching a Wi-Fi hotspot by your robot)įortunately there is a VPN service designed with ROS in mind - Husarnet VPN Client.

Dealing with a high latency (all traffic needs to go throught a VPN server).

Standard VPNs, however, are designed for other purposes than mobile robotics, and are introducting some drawbacks to your system, like: You can solve the issue by using a VPN service. That means you can run a single ROS system containing your laptop and robot connected to the same Wi-Fi router, but you can't if robot is connected over LTE. Remember that roscore must be running on the device indicated as ROS master!!! Connecting ROS powered robot over the Internet Īs mentioned in the previous section you can run ROS nodes even of dozens of devices as long as they are in the same LAN network.

robot: 192.168.1.1 (running roscore - ROS Master).

Let's assume we are connecting robot and laptop devices, with the following IP addresses: While working on multiple machines, you need only one roscore running.

For example if you are connecting robot and laptop, run roscore only on one of those two devices. Remember that only one devices can run ROS Master. To run ROS on multiple machines you need to connect them to the same LAN network at first. To do so, you need to have two computers with ROS. In case you are working on Gazebo simulator, it is possible to setup system to work on multiple computers. In this tutorial you will need a computer and a robot with the same equipment as in the previous tutorials. You will use this configuration to set up system consisting of robot and computer or two computers (gazebo version), which perform task of searching an object.

You will learn here how to configure ROS to work on multiple computers. ROS allows you to run nodes on a single robot and on dozens robots as well, as long, as your devices are in the same network.
