| + | [title] Gearbox function |
|---|---|
| + | [* black] In order to swim like a shark as advertised, the shark uses an impeller to force water through a channel and down to the tip of the sharks pectoral fins, propelling it forward.. This motor additionally drives a gearbox that moves a gate back and forth, alternating which fin is receiving a greater water flow, causing it to swim from side to side. |
