This interface to a Nomadics XR4000 Robot was written in TCL/TK for a complex project whose ultimate goal was to create a fully autonomous object retrieval agent that will recognize generic objects, etc. While I participated in all project stages accomplished thus far, I fully wrote only this interface. The interface did actually control the Robot, and it can also be used for learning TCL/TK, which I found to be most suitable for fast creation of embedded interfaces. The included manual explains how to embed TCL/TK into C/C++ and vice versa.
