Lego Remote Controlled Gearbox Selector

A proof-of-concept to realise the control of two gearbox selectors using a single Lego linear actuator and a single Lego motor.

When the the linear actuator extends it moves two linkages. The bottom linkage has a stretched white rubber belt, and as the belt begins to contract the bottom linkage moves first. Once the bottom linkage can move no further, then the top linkage begins to move.

When the the linear actuator retracts, the top linkage moves first, followed by the bottom linkage.

The gearbox design is a slightly modified version of Sariel's 4-speed Compact Linear Gearbox (http://sariel.pl/2010/07/4-speed-compact-linear-gearbox/).

Unfortunately this set-up only uses three out of the four available gears in the gearbox.

@kippenkopopdekop - Thanks for the compliment. Sorry, I don't have any further details or instructions. I have taken this apart a long time ago now, but you should be able to recreate this fairly easily from the video.

well done - :)

a "remote controlled gearbox selector",

perfect for racing cars or any other vehicles.
