ORION Robot

ORION Mod

A Fabric mod that adds ORION robot from the DFD Workshop to Minecraft: a small differential-drive robot with two articulated arms, tamed with iron ingots, that follows you around like a pet.

ORION is not a made-up creature. He is a real robot built by the DFD Team you can explore more about it on orion_common repository, and this mod is a faithful port of that physical build into Minecraft, geometry and all.

Features

Taming

Right-click ORION with an iron ingot. Each ingot has a 90% chance to bond him to you. Once tamed, right-clicking with an empty hand toggles between following and sitting.

Tamed ORIONs remember their owner across server restarts and chunk unloads.

Movement and animation

ORION follows his owner closely — he starts moving once you are 4 blocks away and stops within 1.5 blocks, at a speed slightly above yours so he closes the gap instead of trailing behind.

His two drive wheels spin as he moves, the arms swing with his gait, and the tilted screen stays fixed at the same 45° angle as the real robot. All animation is procedural Java, driven by his actual movement rather than a looping keyframe track.

Water is his weakness

ORION is not waterproof like in real life (it is a diy robot).

| Condition | Damage | Interval |
|—|—|—|
| Touching water | 2.0 HP (1 heart) | every 0.5 s |
| Standing in rain | 1.0 HP (½ heart) | every 2 s |

Submersion takes priority, so standing in a pond during a storm does not stack both. His pathfinder treats water as impassable, so he will route around ponds rather than walk into one while following you.

Combat

ORION is a utility robot, not a war machine. It is just companion as its original Human-Robot Interaction robot on the real life.

• Damage: 1.0 — half a heart, the weakest meaningful hit in the game.
• One hit, then disengage. After landing a blow he clears his target and refuses to re-acquire one for 5 seconds.
• He never starts fights. He only retaliates when attacked, or backs you up against something you attacked first.

Known limitations

• ORION cannot heal. There is currently no way to restore his health. Combined with water and rain damage, this means damage accumulates permanently. Repairing him with iron ingots is planned.
• No breeding or spawning in the world, he only appears via the spawn egg.
• Uses the vanilla drowning damage type, so the death message reads as drowning rather other behavior.
• Arms are animated but have no distinct idle, wave, or attack poses yet. Wheels keep spinning whether the robot is moving or not.
