3D-printed gearboxes are always an interesting design challenge, especially if you want to make them compact. [ZeroBacklash] created a little strain wave gearbox (harmonic drive) for when you want to ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

In most mechanical systems, metal gears that bend are a bad thing. But not so for strain wave gearing, which is designed to take advantage of a metal gear flexing to achieve an action much like ...
