Over the last few weeks I have been experimenting with building escapement mechanisms out of LEGO pieces. Traditionally, an escapement mechanism is used to power the timekeeping device of a clock, but I wanted to try and use one to power a LEGO model. I decided to build a model of the cow jumping over the moon, from the traditional English nursery rhyme. Here’s the video of it in action along with an explanation of how it works.
There are actually a lot of ways to build an escapement mechanism using standard Technic gears (and if you search YouTube you will find a lot of videos of them). I wanted to do something a bit different, and try to build the gear itself out of LEGO pieces as well, which you can see in the video and the pictures below.
This model will ‘run’ for about 5 minutes before the weight has to be reset.
