After some minimizations of out team due to some changes in our class at school... well... there is just me developing on this. Currently I'm doing an internship in the technology department at company for network controlling devices, so there's again less time for the projekt. But I still developed a new feature for the robot. In the last weeks I played a bit with the W5100 from Wiznet and I think its a really cool chip to rapidly connect a microcontroller to a ethernet network.
I programmed a little webserver, but it is very limited in speed due to the connection with spi... maybe I try the parrallel connection next time. Currently I'm not quite shure where to place the network feature in the robot, but we will see....
