<aside> 📢 This module works well but it is discontinued and not recommended. If you want to stay up to speed with our current development you may want to try the new SD module

The optomotor is an ethoscope module that allows users to deliver both mechanical (tube rotation) and optical (LED) stimuli to fruit flies hosted in individual glass tubes.

The original onshape repository for the optomotors 3D printed parts lives here.

The assembled module will look like this:

Conceptually, the module contains three distinct parts:

• "main", the mandatory components
• "opto", only needed for optical stimulus delivery
• "motor", only needed to rotate tubes

In this document, we describe how to build both opto and motor parts.
