This is a datapack that add some kind of robots I guess. Robots can only follow a path that you made previously, for make it, there are the blocks you can use :

Blocks	Use
orange terracotta	Go Forward
magenta glazed terracotta	Turn with the direction of the arrow of the block
piston	Change the direction, left, then right, then left, etc.
smooth quartz	Wait during 1 step
cut sandstone	Go like stairs : 1 block forward and 1 bloc up
dripstone block	Go Up
oxidized cut copper	Split the Robot in 2, at the right and the left of the Robot. All Robots is copy : armor, items, rotation, mob type.
barrel	Make the Robot wear things and change name : -- First slot for helmet (block and item are allowed) -- Second slot for chestplate (armor only) -- Third slot for leggings (armor only) -- Fourth slot for boots (armor only) -- Fifth slot for first hand (the Right) -- Sixth slot for second hand (the Left) -- Seventh slot for the name ; /!\ only custom name on item work
observer	Make the Robots attack the mob in front of it (make 1/2 hearth damage), item in hand or effect make no damage difference
obsidian	Kill the ArmorStandRobot but delete Robot status from all other entity

Once you make a path, put some Robot on it (I suggest to put Robot on turn block for be sure they follow correctly the path).
For give life to Robots, just set/summon a counter. The counter make Robuts run, if there is no counter, the Robots will stop moving.

Any mob can be a Robot, just make it join the team "robot" with : /team join robot <Entity>
All mob in this team will become a robot without AI
/!\ falling is a bit strange ? Don't worry, that's normal
When the mob-robot is on a kill block (obsidian), it will recover his AI but keep all the things he gain in a robot.

When a robot die or change his clothes and items, the previous one are dropped


If you have any idea for other block or improvments, please say it and I will try to add it.
