Broomba
by Erdragh
Broomba lets players harvest brains from mobs and install them into small roomba-like robots, giving each robot a different behavior.
What it does
A robot becomes active only after it is given a brain, and without one it stays inactive. An active robot roams around aimlessly until its brain sends it to a task. Brains can be taken from mobs such as villagers, which are obtained by killing them, and each brain changes how the robot behaves, for example following a wolf or hunting chickens after receiving a fox brain. Robots can also tend crops, tilling farmland and sucking up grown plants, and they store memories in the brain they hold.
The mod is a technology and mob addition for NeoForge 1.21.10 and requires Geckolib, KotlinLangForge and SmartBrainLib. Servers that run it need every player to install it too. The code is open source under the MIT License, and the source code and issue tracker are public. The first and latest file, 0.0.1, was published on 2025-10-21 on the beta channel.

Farming robots
A robot can till farmland and suck up grown crops, working on its own once it has a brain.
Customizable brains
Brain behavior can be modified, so players can change what a robot does after it is set up.

What the author says
Silly little mod that adds robots in which you put brains. You get the brains by killing villagers. The robot only becomes active if you give it one of these brains, without one it becomes inactive. Active in this case means roaming around aimlessly. They are essentially pets you can en- and disable, inspired by the…
