ROS Programming: Building Powerful Robots

Initializing a ROS network

Before running a ROS node, we have to run the roscore command, right? The roscore command will start a ROS master, and other ROS nodes can find each other through it. In MATLAB, instead of the roscore command, we can use the rosinit function to start a ROS master.

Figure 2 : The rosinit function in MATLAB

The rosinit function can start a ROS master and a global node that is connected to the master. Here, we can see that MATLAB itself can act as a ROS master and other nodes can connect to it. We can also connect to a ROS network from MATLAB. We'll cover that in the next section. In such a setup, the ROS master is ...
