Hi Dannelle,
Sorry I didn't respond for so long...

The various locations are saved as coordinates on a grid. For example, the kitchen has a saved point of (5,20) and the living room has a saved point of (21,6). The grid is a 2-D array in the code that I overlayed on a plan of our house. If I need to change the location, I have to update the (x,y) position. Belvedere does not have voice recognition at this point, but it could be added! Same goes for a remote. The possibilities are endless! Unfortunately, time is not endless :(

Just another thought...my robot's source code can give you many insights into its design. But, you would first need to understand Arduino code (C code). Keep in mind that the source code may not have consistent or complete commenting. This is just a hobby for me and I am busy taking care of my 1 year old son!

I would be happy to answer any questions you have about a specific area of my robot. However, it would be difficult for me to write up detailed instructions for my robot. What areas of robotics are your strengths? Weaknesses? (mechanical construction, electronics, programming). My robot uses similar sensors and controllers as other hobby robots. I just put them together in a way that I wanted so that I could create Belvedere. Here are some websites that helped me learn a lot: Society of Robots (www.societyofrobots.com) Arduino microcontrollers (www.ardiuno.cc) Let's Make Robots (letsmakerobots.com) Ladyada's website (http://www.ladyada.net/make/index.html)
