The review process took a little longer to complete then anticipated, and thus closing registration will be delayed until the 5th November 2014.


    Please note:


    1. Registration closes midnight 5th November 2014. (link on LHS of the web page)
    2. Space at the conference is limited to 160 delegates due to the venue size.
    3. Presenting authors get preference. But unregistered presenters will be removed from the program.

    5. print ready papers are due 12 November 2014.
    Check out http://www.prasa.org/ and http://www.aflat.org/ the joint conference page for more information.
    an AGM is planned for the end of day 2. A full agenda will be available closer to the conference. All delegates are invited to attend. A major item up for discussion is the formalisation of the merging of RobMech, PRASA and AfLaT in the future as a single conference covering all the relevant topics. Please give it some thought.
