UPDATES

This document serves as a log of the updates to the OpenExo platform. It is advisable to check here before doing any assembly or modification work, as there may be updates which simplify/optimize the build process or incorporate subsystems which the reader may wish to utilize.

• Added folder for latest version updates - 4/15/2026

There is now a folder that contains our lab's latest developments. This serves as a repository for those looking to keep up to date with the latest versions of our hardware, electrical components, and software. Our wiki and the standard build guides hosted here should still be your default reference, but consider exploring this folder if curious about our latest innovations. 

Design Update Repository

• Launch of new OpenExo Wiki - 4/4/2026

Welcome to the new Wiki. We've transitioned the site to improve the onboard search function (see magnifying glass icon in top right corner of site). Due to the nature of embedded "Docs", users may need to search both “This Site” and “Embedded Files” to effectively search all of the site's contents.

• Release of OpenExo software v2.0 - 1/21/2026

Read release notes: https://github.com/naubiomech/OpenExo/releases/tag/v2.0

• Release of Ankle Build Guide – 1/20/2026

Detailed instructions for building the ankle bowden cable assembly. Ankle direct drive build guide still in dev. 

• Fixed “if your exoskeleton is not functioning” - 8/29/2025

There was a (not very obvious) emergency stop that prevented users from operating their exoskeletons unless two of the pins on the PCB were shorted. We updated the code to have the emergency stop disabled by default to prevent any issues. For more info and instructions for adding the emergency stop back, see “Emergency Stop” in OpenExo PCB Guide.

• If your exoskeleton is not functioning - 8/26/2025

The cause is likely that the emergency stop pins need to be shorted to each other. For more information, see “Emergency Stop” in OpenExo PCB Guide.

• Added documentation for configuring driver boards for Maxon motors - 6/25/2025

Located in Electrical > Maxon PCB > Configure Maxon Driver Boards. If you’re using the Maxon-series motors (and the Maxon PCB), this guide will walk you through configuring the driver boards (located on the Maxon PCB). Note that as of today there is no OpenExo configuration which uses the Maxon motors; support for these motors is intended to allow users more flexibility for customization.
