Dear Alex,

The gadgets are capable of doing simple web requests, via the gadgets.io.makerequest call. 

This is pretty much detailed in the wave articles. 

Your bot is most probably a standard web application -that is, it can receive web requests. Put these together, and you've got working communication.

As a transport layer, we traditionally stick with JSON, but for simple purposes a basic HTTP POST usually do the trick.

Good luck

Otherwise you can listen for DOCUMENT_CHANGED events in your robot and
pull data out of the gadget state.

...but here's an example, of using makeRequest():
(this is a gadget)

<?xml version="1.0" encoding="UTF-8" ?>
<Module>
<ModulePrefs title="State Example" height="220">
<Require feature="wave" />
</ModulePrefs>
<Content type="html">
<![CDATA[
<style>
#content_div {
height: 100px;
width: 400px;
border: 2px solid #efefef;
font-family: arial;
}
#msg_div {
height: 80px;
overflow: auto;
}
</style>
<div id="content_div">
<div id="msg_div"></div>

<!-- Gadget bootstrap. -->
<script type="text/javascript">
var obj = {
'msgs' : document.getElementById('msg_div'),
'init' : function() {
if (wave && wave.isInWaveContainer()) {
var params = {};
params[gadgets.io.RequestParameters.CONTENT_TYPE] =
gadgets.io.ContentType.TEXT;
var url = "http://www.google.com";
var response = function(data) {
obj.msgs.innerHTML = 'cAllback from makerequest: ' +
data.text;
};
gadgets.io.makeRequest(url, response, params);
}
}
};
gadgets.util.registerOnLoadHandler(obj.init);
</script>
]]>
</Content>
</Module>

Adding to what dougx said, robot can listen for BLIP_SUBMITTED event,
which get triggered whenever gadget makes a state change.
