The Smart Cro is an innovative project.
The SmartCro can do it all. It is basically commands in Vanilla Minecraft.
Right now it is in Alpha and will not be released to the public.
The SmartCro is a scarecrow. It has 3 settings, Weapon-Protection-Drone

Weapon Mode: While in Weapon Mode it will hit anyone but the @p who assigned it with Fireballs, these entities do 100 damage and will cause anyone who is not the @p to die, it shoots one per 15 ticks and is good if you are planning to fight an ongoing hoard. It has a range of 3 chunks away.

Protection Mode: If within 30 blocks of the Scarecrow [adjustable 15-100] it will give you godmode, even /kill cannot hurt you. This is due to its high levels of protection and generates enough health quick enough to survive. You can choose what entities get the protection by selecting them with a Golden Axe, and you can choose "banned" entities from Protection which will basically go on weapon mode on whoever enters the Protection Zone

Drone Mode: This is still in heavy beta, but it will basically act as an entity and travel off of its post, (just the head block) and it will glide across the floor one block at a time. It is very patchy. You enter spectator mode and play as the head. You can shoot entities. It has 30 health and once it dies the machine breaks. Currently no fix. It does 15 damage which is very good. It is very slow.
