Your body stays where you left it
While you pilot, your real body stands in the pose you left it in, holding your real hit points and your entire inventory. It is not protected, and mobs hunt it exactly as they hunt you. If something starts hitting it you hear a low note and see a heart at the edge of your vision; if it drops low you are pulled home whether you like it or not; and if it dies, you die, at home, with a normal death screen.
Tip: Put the goggles on somewhere safe. That is the whole of the safety advice this mod offers.
Charge is the only health bar
A Double has one bar that is battery, stamina and hit points at once. It drains from standing, sprinting, breaking blocks, rain, touching water, and above all from being hit. At zero the call drops in a frame of static and the Double becomes an inert wreck exactly where it stood, cargo intact. Walk out with some coal, charge it up, and it is a machine again. A robot in an unloaded chunk never simulates: it is frozen as you left it, not quietly running itself flat while you sleep.
Worse than you, on purpose
Ender pearls and chorus fruit are inert in its hands and portals refuse it; a robot never crosses a dimension, though you can build one in the Nether or the End and it simply lives there. It sinks in water and walks the bottom at a trudge. It has six fixed colour-coded pockets, no mouth, no hunger and no experience, and water on its plating is damage.
Two chassis
The Stand-In is one block tall, costs 5 copper, 2 iron and a redstone block, runs about fifteen minutes, and its size is a feature: it walks through one-block gaps, crawlspaces and the corridor behind your redstone. The Stunt Double is player-sized, sprints, jumps and sneaks, runs about an hour, takes hits at a kinder charge conversion, carries six extra slots, and costs 4 iron blocks, a copper block and a redstone block. It does the dangerous work, which is where it gets the name.
Power with no cables in it
The Charging Stage is a low pad that burns ordinary furnace fuel out of a visible store; feed it by hand or hopper and read it with a comparator. A Solar Panel feeds any stage it touches, including from directly on top, and several panels stack. Adjacency is the entire power network. A Double below a quarter battery will walk itself to a stage within twenty-four blocks with nobody inside it.
Tip: The self-walk means a robot parked near a stage largely looks after itself.
Five upgrades, all worn on the outside
Sneak-click an unpiloted Double with a part: Waxed Plating shrugs off rain and spray, a Solar Head trickles daylight charge, a Battery Pack adds half again as much battery, a Cargo Rack adds a storage row, and a Voice Box shows what you say in chat under the robot's name. A Stand-In takes one part, a Stunt Double two, and every fitted part is visible, so you can read a robot's kit across a field. Shears take them back off.
The Clapperboard teaches one a job
Use it while piloting and the Double records what you do: where you walked, what you broke and placed, what moved between which chests. Sneak-click an unpiloted Double with it to schedule the Performance: every one, five or fifteen minutes, or on a redstone pulse. It runs the routine alone, spending charge as it goes, and refuses to start below a quarter battery, because charging beats acting. Move the robot more than eight blocks off its first waypoint and the show stops; that is how you cancel one.
The mod never says a word
No chat messages, no commands, no config file. Everything it has to tell you arrives as a sound, a light or a glyph beside the charge bar, and every gesture is an item in your hand. Robots themselves are ordinary objects: push them, boat them, put a lead on one, or mine one with a pickaxe to fold it back into an item with its cargo intact.
