This is going to demo using the rails block, this allow one machine to run along a rail. In this case I’m using it to create a secret opening to a cave
So that’s great (he says modestly) but pushing things along rails can get boring fast. So can you power the rail so that it can move on its own?
I wouldn’t have asked the question if you couldn’t, so here’s the video
So a rail can be controlled not only by a button directly but remotely using antennas, which is, if I’m honest, much more useful.
You saw there was an addition/subtraction block. This is because a positive signal will move the rail one way, and a negative signal the other way
