NASA未來會派人到月球，這些人需要房子住跟工作的地方。NASA會用月球上的石頭蓋房子，就有人想到可以用機械推車來運送石頭。
The robot carts have magnets, so they float over a track. They don't have wheels or legs. They don't touch the ground, so moon dust can't stop them.
這種機械推車有磁鐵，讓它懸浮在軌道上，不需要輪子或是雙腿，這樣月球上的灰塵就阻止不了它。
The track pushes the carts. They can move thirty meters in one minute.
軌道會推動推車前進，一分鐘可以跑30公尺。
Like toy tracks, the robot cart tracks can be moved. They can be rolled out on the ground. Then they can be rolled up and put away!
跟玩具軌道一樣，推車的軌道可以隨意移動，也可以收起來。
Robot carts are a great idea. But there are many great ideas. Will we see these robot carts on the moon one day?
