harriedegroot posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
A compact sequential heavy-duty 4 speed remote controlled AWD gearbox Each gear of this remote controlled gearbox approximately doubles the speed of the previous. The output shaft contains an integrated lockable differential for AWD. See the video for a WORKING DEMO | FREE INSTRUCTIONS below.

[MOC] 4 Speed rotary gearbox. Has this has been done like this before?
TechnicBrickPower posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi Everyone, I have created this 4 speed gearbox based on the "change over rotary catch" component and I have used it to select 1 of 4 gearing inputs in possibly a new way by connecting to four clutch gears which then connect to a differential housing used as a method to transfer motion whilst allowing the rotary catch to be rotated freely inside of it. The gearbox implements 3 forward speeds, and 1 reverse. I was wondering if anyone has seen this technique before (I am guessing yes since most ideas are not new)? Anyway thanks in advance.
