Which humanoid robots have open-source software (or hardware)? Apart from iCub, whose open-source software can be found at https://github.com/robotology/icub-main, what other humanoid robots have open-source and freely accessible software (or hardware)?
There are quite a few ROS (Robot Operating System) based humanoid robots. Not all of them will be open-source down to the firmware level but most will at least be to the control level. I'm not aware of any that have open-source hardware as well.

Some examples include:


Talos
Reem-C
Nao
OP3
