The training approach uses hardware to demonstrate actions—motors physically pull the trigger and drive the ball to show the rat what to do before they try it themselves. It's reinforcement learning implemented in hardware rather than pure trial-and-error. What you get: - All 3D-printable designs, circuit diagrams, firmware, and control software on GitHub. Build guide included. v1 was featured on Vice and PC Gamer. v2 is fully modular and ready to replicate.

Hey ProductHunt 👋
Viktor here. Started this in NYC training rats with a basic rig. After press coverage (Vice, PC Gamer), life happened, project paused.
Public interest reignited it. Teamed up with electrical engineer Sándor Makra for v2—completely rebuilt, modular, documented by Akos Blaschek for open-sourcing.
Our rats (Todd, Kojima, Gabe) aged out before full training, but the hardware is validated and ready to replicate.
Why share this? Because the weirdest projects often demonstrate the most transferable skills: cross-domain engineering, hardware/software integration, behavioral systems design.
Fork it. Break it. Teach hamsters to speedrun. We're here for questions, at https://ratsplaydoom.com/ 🐀
