  This work-in-progress paper presents our work with a domain specific language
(DSL) for tackling the issue of programming robots for small-sized batch
production. We observe that as the complexity of assembly increases so does the
likelihood of errors, and these errors need to be addressed. Nevertheless, it
is essential that programming and setting up the assembly remains fast, allows
quick changeovers, easy adjustments and reconfigurations. In this paper we
present an initial design and implementation of extending an existing DSL for
assembly operations with error specification, error handling and advanced move
commands incorporating error tolerance. The DSL is used as part of a framework
that aims at tackling uncertainties through a probabilistic approach.
