This paper describes the design and acquisition of a German multimodal corpus for the development and evaluation of computational models for (grounded) language acquisition and algorithms enabling corresponding capabilities in robots. The corpus contains parallel data from multiple speakers/actors, including speech, visual data from different perspectives and body posture data. The corpus is designed to support the development and evaluation of models learning rather complex grounded linguistic structures, e.g. syntactic patterns, from sub-symbolic input. It provides moreover a valuable resource for evaluating algorithms addressing several other learning processes, e.g. concept formation or acquisition of manipulation skills. The corpus will be made available to the public.
