I think Ethernet connection will be easy. Lots of MCUs have Ethernet Interface (i.e. NXP1768, mbed has Ethernet library). However EtherCAT may give you more benefits but needs extra Interface module or chip which I&#39;m looking for.<br>

Hi Marcus,<br><br>There is an ARM port of rosserial, check out the following two links from the mbed community:<br><br><a href="http://mbed.org/users/nucho/libraries/rosserial_mbed_lib/m65thk" target="_blank">http://mbed.org/users/nucho/libraries/rosserial_mbed_lib/m65thk</a><br>

<div>Do you think rosserial could be easily extended to work with an Ethernet connection instead of USB or UART?</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>Marcus</div></font></span><div><div class="h5">

<div><br></div><div>@ rosserial: I took a brief look and it indeed looks very interesting. However, I couldn&#39;t find code for ARM and so I assume a port would be necessary.</div>

<div><br></div><div>@ <span>Synapticon: Do you think that the implementation/idea of rosxmos will be easily adaptable/expandable to be used on other platforms such as ARM and Atmel (Arduino)? Maybe we could develop some core components together and one writes the platform-specific parts as needed. </span></div>
