The normal paddle wheel is a large wheel, built on a steel framework, upon the outer edge of which are fitted numerous paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels underwater. Rotation of the paddle wheel produces thrust, forward or backward as required. More advanced paddle wheel designs have featured feathering methods that keep each paddle blade oriented closer to vertical while it is in the water; this increases efficiency. The upper part of a paddle wheel is normally enclosed in a paddle box to minimise splashing.
When we were doing the research, we found the following picture and got the idea about the paddle wheel which we can make successfully with our wood workshop. It was supposed to use the rubber band to provide the kinetic energy.
