Also check out CraftedPixel's carpet invisible maze in MCPE:
This is a redstone alternatives version of invisible maze in Minecraft PE. In this maze you need to push a minecart with chicken to the destination (quartz platform), however you need to push it along the invisible path. If you push them away the path (push them "into" "invisible walls"), you have to push the minecart again from the start. Once you successfully push the minecart to the destination, the door will be opened in a few seconds.
Here shows you a sample of the invisible minecart maze:
The invisible minecart maze:
The invisible minecart maze with the path shown:
Redstone alternatives / mechanism behind:
Minecart will "teleport" to the track if it is less than around 1.5 blocks above the block where the rail is being placed on (see the GIF below on what conditions the minecart will teleport or not).
In the maze, each "invisible wall" block have a (gold) block below them with a power rail on top, therefore when a minecart is being pushed onto that block, it is being teleported below and continue moving because it has momentum while being pushed. I call those rails "absorbing rails". All the absorbing rails beneath are connected to other non-absorbing rails which deliver the minecart back to its starting point.
If you push the minecart to the destination, there is another set of rails beneath the destination which will deliver the minecart to the minecart pressure plate, using the same principal. The door is then opened when the supporting signs are being desrtroyed.
Note:
1. When placing rails beneath the maze, all the absorbing rails below the invisible walls should be powered rails, so the minecart can have enough energy to return to its starting point / enter the minecart pressure plate system.
2. Do not place blocks adjacent to the absorbing rails which bounces back the minecart , because in some cases, the minecart will teleport and stuck into that block.
