The idea behind the tugboat was to create a functional mechanism, but with a certain spice that would make it both down-to-earth and interesting. And of course – it was supposed to be a type of marine transport. We like to think that many of you enjoy watching the working of the gears as much as we do, this is why the detailed body of the Tugboat is designed to expose the beautiful mechanism in motion. This way you will be able to fully appreciate the main technical features we implemented in this model. The Tugboat is driven by a rubber-band motor powered by the tension of the rubber connected with a bearing. The reduction gear transfers energy to the drive wheel and further to the asymmetrical wheel pair. The pendulum slows and evens the motion of the tugboat. The asymmetry of the wheel pair grants the model its unique way of moving, imitating a boat rocking on the waves, while the working pendulum creates a specific noise similar to one produced by the real-life diesel motor many boats are equipped with.
