OSR2 — Complete Guide

What Is the OSR2?

The OSR2 (Open Source Robot 2) is a community-designed, open-source multi-axis stroking device. Created by user "TempestMAx," the OSR2 adds three axes of motion — stroke, pitch, and roll — providing a far more immersive experience than single-axis devices. It is typically either self-built or purchased as a pre-assembled unit from community vendors.

Key Specifications

Setup Walkthrough

1. Assemble the OSR2 (if DIY) following the build guide, or unbox a pre-built unit.
2. Connect the external power supply and the USB cable to your PC.
3. Install the Arduino driver if prompted by Windows.
4. Open MultiFunPlayer (recommended for multi-axis).
5. Add a "Serial" output device, select the correct COM port, and set baud rate to 115200.
6. Map axes: L0 → stroke, L1 → pitch (surge), R1 → roll (twist).
7. Load a multi-axis funscript and video, then play.

Pros

• 3 axes of motion for significantly more realism
• Open-source — fully customisable and upgradeable
• USB connection: zero latency
• Uses TCode protocol — supported by MultiFunPlayer and others
• Growing library of multi-axis funscripts
• Community-driven with active development

Cons

• Requires technical skill to build (if DIY) or higher cost for pre-built
• Must be tethered to PC via USB
• Louder than commercial devices (servo motors)
• Not as polished or compact as The Handy or Keon
• Multi-axis scripts are less common than single-axis scripts
