Hey everyone, Jason here. Today I’m excited to show you my latest LEGO creation, which is this kinetic sculpture of a horse.
So there’s quite a bit going on here to try and replicate the motion of a galloping horse including the obvious motion of the legs, the rocking up the body, the slight forward
motion of the head, and also this little flick of the tail.
So let’s take a look at what is going on. On this partial model of the horse you can
see the gearing system that I’m using to transmit power up through
the stand and into the body of the horse. This gear drives the
front legs and this gear drives the rear legs. So let’s take a look at the legs. Here we have a relatively complex system Of one, two three, four, five, six, seven links. The front legs actually use the same system as the rear legs, just driven in reverse. For the
rocking of the body we have this relatively simple lever system here, which is driven in
time with one of the rear legs. This lift arm, that is part of that
system, is also used to you give the little flick of the tail as the back on the horse reaches its apex. To show you the motion of the head we’ll take a look at the main model again. Here you can see that the base of the neck is anchored to the stand, which doesn’t move and the top at the neck is anchored to the body. So as the body rocks back and forth, the neck slightly deforms, which causes the head to move forwards and backwards. I had a lot of fun building this model. It was definitely a challenge to reproduce the fluid motion a horse using LEGO parts. I went through a lot of prototypes as I
was refining the movement but in the end I think it was worth it.
I hope you enjoyed the video, keep on building, and we’ll see you next time.
