%T A Native Transterpreter for the LEGO Mindstorms RCX %A Jonathan Simpson, Christian L. Jacobsen, Matthew C. Jadud %E Alistair A. McEwan, Steve Schneider, Wilson Ifill, Peter H. Welch %B Communicating Process Architectures 2007 %X The LEGO Mindstorms RCX is a widely deployed educational robotics platform. This paper presents a concurrent operating environment for the Mindstorms RCX, implemented natively using occam\-pi running on the Transterpreter virtual machine. A concurrent hardware abstraction layer aids both the developer of the operating system and facilitates the provision of process\-oriented interfaces to the underlying hardware for students and hobbyists interested in small robotics platforms.
