Pollen Robotics has created the Reachy robot. They manufacture and sell that robot, but they have also provided an open source version (see the Important Links section for details).
The Circuit Launch CoLab project is attempting to create its own Reachy, using the open source info from Pollen.

The initial team goal was to create a full replica of Reachy. Given the large number of unknowns (especially surrounding FDM printing), that goal was eventually narrowed down to a more manageable goal.
