MOTUS

6-DoF, almost fully 3D-printed student arm; repo files are empty placeholders, blueprints are on Instructables (non-commercial).

Dormant. No upstream changes for two years or more. It may still build, but parts, firmware and docs may have drifted.

Last push to ELISAVADevelopmentLab/MOTUS: 2022-06-05 (GitHub, checked 2026-10-01).

About MOTUS

MOTUS is an open-source, almost entirely 3D-printed 6-DoF robot arm created by three fourth-year Industrial Design Engineering students at ELISAVA Development Lab. The README describes a 600 mm reach, a payload of up to 500 g, Arduino-IDE-based control, and a repository organised into BOM, CAD, STL, firmware and user-manual sections. In practice the repo (last updated 2022) contains only the README and an MIT LICENSE: the BOM, CAD Files, FIRMWARE, STL Files and USER MANUAL folders each hold a single empty 1-byte placeholder, so none of the promised hardware artifacts are in the repository. The authors' Instructables page (2022) publishes a 40-page blueprint PDF and an Arduino sketch under CC BY-NC-SA 4.0, but no STL, CAD or itemized BOM. It is a clear and appealing concept but, as published, not reproducible from the repository alone.

MOTUS bill of materials

Cost to build

The sources do not publish a cost total.

No itemized bill of materials is published in the sources, so none is shown here.

  • README says the repository contains CAD, STL, user manual, firmware and Bill Of Materials, but the pinned tree shows each promised artifact folder contains only a one-byte placeholder file. README.md
  • Pinned tree review: BOM/BOM_MOTUS, CAD Files/MOTUS_CAD, STL Files/MOTUS_STLFiles, FIRMWARE/MOTUS_FIRMWARE and USER MANUAL/MOTUS_UserManual are one-byte placeholder blobs with no usable itemized content. BOM/BOM_MOTUS

MOTUS source files

1 files

Files stay in the upstream repository under their own licenses; these links open them there.

MOTUS in simulation

Robot description files a simulator or CAD tool can load, linked at the commit they were found.

No URDF, MJCF, SDF, USD or Onshape model has been found in the sources.

No 3D model has been generated from the project's files yet.

Builds of MOTUS

0 reviewed

No reviewed builds of MOTUS yet.

A build log records the evidence (photos, a video, your repository), what the build cost, how long it took and what you changed. Each one is checked by Motari (until a maintainer claims this page) before it shows here, and reviewed builds count toward the reproducibility score.

How this page was made

Assembled from public sources on 2026-06-04, not yet reviewed by the maintainer. Each figure links to where it is stated; a value the sources do not state reads "not published". Last source review: source-reviewed 2026-06-08.

Original files stay intact and separately licensed; Motari adds only the summary on this page. Maintainer? Request a correction or removal.

Not fully met yet: cad / mesh present, bom evidence, wiring diagram, firmware linked (partial), build instructions (partial), oshw-compatible license. The score is read from the project's own sources, so publishing what is missing is what raises it. A score of 90 or more needs a reviewed build. How the score is computed
