Future sensors will include...(1) Temperature Sensor (2) Video camara (5) Sonar Ranger (6) Sharp IR detector and (7) Miniture CCD camara.... visit my site at www.metrorevolution.com.... The network when completed, will have my 600MHZ pentium 3 pc as the MASTER and the robots as the SLAVE..They will communicate via a wireless 433mhz link.... The main PC will keep track of the robots position and will be able to transmit voice to the robots and reveive VIDEO from them... I also plan to run a text to speach engin on the main pc to enable email to be read through the robots...I am presently working on the sonar ranger....
