Design a forward-moving, back-ward moving, steerable,
hand operated, electrically-controlled vehicle with materials available to you.
The following slides are intended as a guide for construction. Students
are encouraged to come up with their own creative solutions other
than offered here and substitute materials that are available to them.

The frame of a vehicle is called a chassis. Design one or modify
that meets your needs and materials available to you.
The Rollaguggy uses a tin can for wheels and as a pulley to
attach a rubber band to. These examples do not steer.
Rubber Bands also supply traction.
The first configuration can make
use of the steering mechanism by
omitting the front can and replacing
it with a single wheel.
Steering the tin can.
The vehicle turns when it goes in reverse.
Forward – friction pushes wheel back
against rear stop, vehicle goes straight
Reverse the tin can. - friction pushes wheel
