In this video, I demonstrate 5 useful mechanisms in LEGO. These ones are more centered on assemblyline mechanisms (for an upcoming video), but I hope it can be used in other applications as well. As this is Mechanical Principles 10, I most likely will pause this series for a while. Do not worry though, I still plan to demonstrate interesting mechanisms in the future.

Turn on subtitles for more explanations about the mechanisms.

0:00 Pneumatic Square Motion Mechanism
0:38 Inverted Rotation Linkage
1:17 Geneva Mechanism
2:04 Double Worm Gear Mechanism
2:47 Pick and Place
3:26 Back and Forth Arm
4:14 End Screen

The Inverted Rotation linkage comes from the following video:
   • Lego Sketchbook  1  Axle rotation i...  

The Geneva mechanism design was inspired by the following video:
   • Geneva drive (improved ver.)ゼネバ機構　改良版  

The Double Worm Gear Mechanism was inspired by the following video:
   • LEGO unique worm gears system  

I apologize for the spelling error in the last mechanism, it should be spelled "forth" not "fourth"
