Duckling (toy)

Input: red crank rotating regularly.
The slider crank mechanism (red crank, green conrod, orange slider) causes the linear reciprocating motion of the duckling. The chain drive helps the mechanism overcome unstable positions. For more about this mechanism see:

The mechanism installed on the blue slider causes the duckling to rotate 180 degrees. To understand this mechanism, see:
