Overview

What is the OSR2?

The OSR2Open-source Stroker Robot, 2-axis (OSR2) is a Multi-Axis Stroker Robot (MAxSR) designed to hold and move a standard fleshlightFleshlight or similar toy with 2-4 degrees of freedom (adapters are available for soft, sleeveless toys like onaholes).freedom.

It is constructed from a combination of 3D printed plastic and commercial off-the-shelf components.components Itand is designed to be home built, modifiable, and user-repairable.

ControlThe base model can move up and down while rolling left and right. Additional modules can be added to allow for pitch and twist (an OSR2 with a pitch module added is donetypically viareferred ato genericas openan OSR2+).

The operation of the OSR2 is managed through an open-source USB serial protocol calledknown as T-Code.Code. TheThis OSR2protocol usesis designed to interpret and transmit commands to the device's microcontroller, typically either a Romeo BLE min arduino-based microcontroller,Mini or an ESP32. The microcontroller tois receiveresponsible thesefor simpleprocessing the received commands and calculatedetermining the appropriatecorrect control angles for each of the servos to achieve the desired position for the receiver.

The OSR2 is a hands-free machine that mounts to a standard VESA 100mm hole pattern using 4x M4 bolts.bolts, Thiswhich meansallows thatfor an enormous range of mounting options, mostly inoptions; the formmost ofcommon being commercial display and monitor stands,stands. areOther commerciallyoptions available.include Therecustom are3D also a couple of 3D-printable desk and chair clamp options availableclamps.

This receiver can be added to the side of the device to add an extra axis. This configuration is called the OSR2+ and is also capable of pitch forward and backward.

In the OSR2, the standard fleshlight is mounted into a ring-shaped part called the receiver.
