- The project explicitly prioritizes accessibility, repairability, and suitability for learning experiments over raw performance or advanced capability.
Key quotes
If you are looking for the most advanced humanoid robot, this is not it. If you are looking for a humanoid you can build, understand, repair, instrument, simulate, and use for learning experiments, this is the robot we are trying to make.
