Automatically Reversing Gearbox

[TechnicBrickPower]

Hi Everyone,

This gearbox has been designed to automatically reverse if there is a high load on the output. The gearbox works by using a differential to react to the torque on the output and it drives a two state switch to select the reverse or forward direction in the gearbox.

Might be usefull for GBC  if can be made more compact.

Such as MOC - Improved GBC Reverser?

Thanks for posting that  info, will build it and  see if it works for GBC Train module I am developing.

Hi Doug72. I am sure it can be - at least one differential can be eliminated by replacing it with a different reversing mechanism. Also I think there may be other torque conversion options instead of a differential so then they'll be both gone and the mechanism will be a lot smaller.

Nice work, as always!  Long ago I made a two-stage oscillator with some similarities:

(Honestly I'm not sure if I quite remember how it works!)

I expect you could make a better and more robust version...
