ROVERBOT is an autonomous robotic platform that moves on wheels and has the ability to be self-guided or remote controlled (localy or via wireless LAN or Internet) Its basic principle are two indipendent motor wheels (and a third one, smaller, free turning wheel, for support) so that their speed divergence makes ROVERBOT turn (just like a tracked vehicle), making unnecessary the use of steering gear and therefore facilitating spatial placement Dimensions : Length : 56cm Height : 34cm Width : 56cm Weight : about 50Kg Cost : about 650 euro, (expected to reach 1500 euro). History : I started designing ROVERBOT in 1992 wanting to experiment and acquire some real experience in robotics, but mainly to build a platform for further experimenting in self-direction , automated map-making and other applications of Artificial Intelligence and Neural Networks. Besides the subsystems of stepper motors and their drive circuits that I designed (and build as prototypes) in 1996 , all the rest was manufactured between May and October 2002.
