Hi,im Steven Frye and I love robotics I live in Alabama and navigator1 is my first robot attempt its a simple robot it has one momentary switch in the froint its on the left side when it gets bumped it causes the robot to turn right and starts a new path. Most of my parts came from Radio Shack here's a list of the parts I Bought. Two electric motors there 1.5 volts thru 3 volts they costed about $1.45 each. A pc board which I used for the body it costed $5.95. Momentary switchs which costed $2.45. A AA battery holder which costed $1.95. A pack of spst switches which costed $2. A blinking led which I used for the on indicating light it costed $1.45. Every thing else came from the robot junk heap. http://hometown.aol.com/botnerd/StevensRoboticsindex.html To find out more about Navigator1 and my future robotics project email me at Botnerd@aol.com
