Reinforced Bots

The code mod that brings the robots in the reienfored bots pallet to life.

Each robot in the pallet is a real physics body: rigid parts on motorised joints, with nothing animated and nothing scripted to move it. This mod gives each one a trained brain - a small neural network that learned to balance and move that exact body by reinforcement learning - and runs it while the robot is spawned. Without this mod the robots spawn and just fall over.

You need both: this mod, and the reienfored bots pallet (the spawnables themselves).

The robots

Spawnable	What it is	What it does
Atlas	Hydraulic humanoid	Stands, walks about near where it was spawned
Advanced Atlas	Detailed humanoid, 1.8 m	Walks, idles, catches itself when shoved
Smart Advanced Atlas	Advanced Atlas with a squad brain	Three or more that meet vote a leader, patrol in formation, and answer gunshots by scattering or attacking
Unitree G1	Humanoid that learned by copying a person	Human-style walk and idle
Spot	Robot dog	Walks, trots, handles rough ground, gets itself back up
Izhevsk Walker	Cow-sized four-legged robot, 700 kg	Walks, trots, climbs, gets itself back up
BullCrab	Big four-legged crab	Wanders; chases you if it sees you
Heavy Drone	Four-thruster drone	Really flies - held up only by its thrusters - from point to point

Robots that cannot get up by themselves yet are stood back on their feet after a few seconds on the floor.

Smart Advanced Atlas

Spawn three or more near each other. Robots within about 7 ft of each other can "talk"; a group of three or more votes for a squad leader (a tie means a revote), then patrols behind it. A gunshot the leader can hear makes it give one of two orders: scatter (everyone splits up, then regroups at a rally point) or attack (everyone closes on the shooter). They plan their routes on the level's navigation mesh, or map the floor themselves where there is none. What they say to each other is printed in the MelonLoader console as [Alyx] lines.

Settings

UserData/MelonPreferences.cfg, section [ReinforcedBots]:

• AtlasSpeed - how fast the Atlas and Advanced Atlas walk between spots, in m/s (0 = stand in place)
• ShowPlans - draw each Smart Advanced Atlas's planned route as a line

Installing

Use a mod manager, or drop Mods/ReinforcedBots.dll into your BONELAB Mods folder. Requires MelonLoader and BoneLib.

Notes

• The brains were trained at 50 physics steps a second; BONELAB runs its physics faster, so balance can be a little worse in game than it was in training.
• The robots ignore loose props when they look at the ground ahead, so they can trip over clutter.
• Not networked: in a Fusion lobby each player sees their own robots.
