About SigmaBan (Rhoban)
SigmaBan2019 is the kid-size humanoid soccer platform from the Rhoban team (LaBRI / University of Bordeaux), multiple-time RoboCup Humanoid League champions. This page covers the version published in Rhoban's onshape-to-robot-examples repository, where the robot is exported as a fully articulated URDF and MuJoCo model with per-link STL, .part and OpenSCAD pure-shape collision geometry. It is a Dynamixel-based design (MX-64 / MX-106 class actuators with RX64 caps), instrumented with foot load cells, a 4S LiPo, a PointGrey camera and an Intel NUC. The repo is a simulation/export reference rather than a full build kit: there is no costed bill of materials, wiring diagram, or firmware here, but the geometry and joint model are complete and directly loadable in PyBullet and MuJoCo.

How to build SigmaBan (Rhoban)
4 stepsSteps marked Motari summary condense the linked source; follow the source for exact instructions. Upstream step marks a step taken from the linked guide.
Install onshape-to-robot
pip install onshape-to-robot. The repo ships the config.json and the resulting export so no Onshape API key is needed to view the result.
Motari summarycad.onshape.com/documents/41654e89e61a392d020b728c/w/d555cee...Load the URDF in PyBullet
Run onshape-to-robot-bullet sigmaban2019_urdf to load the full articulated humanoid with pure-shape (OpenSCAD) collisions.
Upstream stepgithub.com/Rhoban/onshape-to-robot-examples/blob/7e40fd65320...Load the MuJoCo model
Run onshape-to-robot-mujoco sigmaban2019_mujoco to simulate using robot.xml and scene.xml.
Motari summarycad.onshape.com/documents/41654e89e61a392d020b728c/w/d555cee...Re-export from Onshape
To re-export, make your own copy of the Onshape document, put its link in config.json, set your Onshape API key, and rerun onshape-to-robot; install openscad and meshlab to get the same results.

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The sources do not publish a cost total.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 identifies Sigmaban2019 as a 20-DOF humanoid Onshape-to-robot example with URDF/MuJoCo visualization commands and configuration links, but does not publish a build BOM, wiring list, or kit total. README.md
