Introduction

The Big Mouth Billy Bass (figure 1) is a robot that begins to sing and move when someone walks up to it. The Big Mouth Billy Bass evolved from a stuffed fish mounted on a plaque. The Big Mouth Billy Bass is approximately 14 inches long, 4 inches wide, and 4 inches thick. The Big Mouth Billy Bass consists of a variety of different materials such as plastic, latex rubber, wires, wood, and metal. The Big Mouth Billy Bass consists of five essential parts: plaque, speaker, skeleton, motor, and fish.

Plaque

The plaque, made of wood, holds the Big Mouth Billy Bass. The plaque has five different inside components that control the fish: a printed circuit board, a speaker, a movement detection photocell, a battery pack, and an on-off switch.

 

Speaker

The speaker, made of metal located on the back of the plaque, duplicates the music transmitted to it by the integrated circuit.

 

Skeleton

The skeleton, made of plastic, has three moving parts. The skeleton tail flaps back and forth. The skeleton body swings out and away from the plaque. The skeleton mouth moves up and down to replicate singing.

 

Motor

The motor, made of metal and wires, powers the jaws and vocalize the singing. The motor moves the body part in a single direction. The motor, when stopped, signals the jaw to close and when open, signals the jaws to open.

 

Fish

The fish, made of plastic, resembles a stuffed bass. The fish lip-syncs to a short thirty-second clip of a celebrated song or famous one-liner.
