Everything will be much easier if .detect() returns block id.

Hehe, the purpose of the setup is to test if they turtles are able to start up another recently placed turtle and then launch that turtle. Of course i'll agree that it will be the best if im able to create self-replicating turtles with just ComputerCraft alone. Also, the setup above was using the previous version of computercraft which doesn't include fuel and crafting table. The later version made the process harder due to the fact that turtles constantly needs fuel. The only idea i can think of is to constantly plant sapling and converting wood to charcoal to provide fuel for the rest of the crew (Which take foreverrrrrrrrr). And then the turtles will have to constantly mine blindly like a quarry because of their range of sight. The turtles will have trouble identifying blocks id since .compare() require a comparing block. It's not impossible and i'll update and try it when im free.

Just tried it with crafting tables, my Java crashed half an hour due to insufficient memory
