Another strong author on robotics in the Netherlands is Christoph Bartneck. He works at the TU/e, faculty of Industrial Design, sub-department Designed Intelligence (which is only slightly less scary than intelligent design). His list of publications on robotics is very impressive. Recently, there are a couple together with Mathias Rauterberg, the prof who heads the DI group, but these are not specifically about robots.
Through his publications, I found out there is a conference called ACM/IEEE international conference on Human robot interaction (yearly since 2006). Proceedings here. Quite a lot of interesting papers there.
