Check basic YARP functionalities

The first step is to have the yarpserver running.

At a terminal type:

yarpserver

Depending on your system the console will look something like this:

If you type on a web browser http://127.0.0.1:10000 you get information about the name server (registered ports, info, etc.).

We can just check functionality by running a simple example. On another terminal type:

yarp read /portread

on a third terminal:

yarp write /portwrite

and on yet another terminal:

yarp connect /portwrite /portread

you'll see the effect on the name server:

yarp: registration name /portwrite ip 127.0.0.1 port 10012 type tcp
yarp: registration name /portread ip 127.0.0.1 port 10002 type tcp

Now, anything typed on the YARP write will be sent and printed on the read side.

Play a recorded sequence

You can also use the yarpdataplayer to replay a recorded sequence. This will reproduce all the sensory information available on the real robot during a simple experiment. Follow the instructions here:
