Open-Motion Hardware Development¶
Overview¶
All hardware developed using Openwater's base platform is released under Creative Commons — ShareAlike 4.0. The hardware is separated into one and two-sensor-module CAD assemblies. Part numbers and quantities are provided in the tables below.
CAD files¶
Released design files for Open-Motion are stored in the Mechanical and Electrical repositories on GitHub:
- Mechanical:
openmotion-mechanical - Electrical:
openmotion-electronics
Mechanical¶
The mechanical repository provides:
- 3D mechanical parts and assembly models for Open-Motion devices, including sensor modules and housings
- Useful when you need physical dimensions, mechanical constraints, or to integrate Open-Motion with custom enclosures
- Best fit for: mechanical CAD work and physical integration requirements
Sensor Module assembly¶
Top-level mechanical assemblies for the Open-Motion device:
| Part name | Part number |
|---|---|
| Motion Console with power cable and USB cable | 700-00013 |
| Motion head strap, arm/leg strap, torso strap | 700-00029 |
| Sensor module with cable (Console to Sensor Module) and protective cover | 700-00031 |
Electronics¶
The electronics repository contains:
- PCB designs for the Open-Motion platform (Console and sensor modules)
- Board-level schematics and layout sources for building or modifying hardware
- Best fit for: electronics hardware build files
Open-Motion PCBs¶
Electronic board designs for the Open-Motion device:
| Part | Board design | Schematic | Status |
|---|---|---|---|
| Console Board | 710-00024 |
720-00010 |
In design |
| Camera Board | 710-00021 |
720-00007 |
In design |
| Aggregator Board | 710-00019 |

Released |
Design status
"In design" means the board is actively being revised and not yet released for fabrication. "Released" means the board files are stable and have been fabricated and validated. Always check the latest tag in the repo before sending files to a fabricator.
Building your own hardware¶
If you intend to fabricate Open-Motion hardware, please:
- Use the released revision of each board file from the Electronics repository.
- Source the BOM components per the released BOM (component substitutions may affect optical or thermal performance).
- Follow the assembly instructions in the Mechanical repository for housing and cable routing.
- Do not modify the laser safety circuitry without a corresponding update to the safety FPGA logic. Disabling or bypassing safety interlocks is strictly prohibited under the Class 1 laser certification.
- Perform the verification tests described in Best Practices → Verification & Validation before any operational use.
Class 3 laser safety
Modifications to the Console enclosure, optical path, or laser safety interlocks can expose users to Class 3 laser radiation. Such modifications immediately void all warranties and shift all liability to the modifier. See the Investigational device disclaimer for full terms.
