Pongo by Ron Woodward

Pongo was built to compete in The Fire Fighting Home Robot Contest 
held by Trinity College in Hartford Connecticut. Pongo stands about
10 inches tall and is 10 inches in diameter at the bump ring. His
body is made from a 1 gallon ice cream container (Getting the parts
sure was yummy). He uses differential steering produced by two
Johnson motors driving inline roller skate wheels. He has two nine
volt battery packs one for the motors and one for the electronics.
He has active optical wall sensors and dual quadrature encoders on 
the wheels. He uses an automotive windshield washer pump to spray 
water to put the fire out. He has an internal microphone to detect 
a fire alarm to begin his search for the fire. A Pic16c74a controller
operating at 14mhz  provides the brains. Pongo failed to finish his
first year at Trinity mostly due to software problems. He will be 
ready to take on the field in 98 with improved software incorporating
PID speed control and a new H - bridge motor drive.
