#2the cost-effectiveness/performance factor benchmark is interesting, but it feels slightly misleading - I just don't see how "average peak torque of all actuated DoFs, normalized by the robot's size" is related to measuring "accessibility and customizability" of the robot.

What is interesting is that on their own metric, the Berkley Humanoid is only twice as expensive as the Berkley Humanoid Lite but has more than twice the "performance factor" (0.36 vs 0.14).
It shows they threw away too much while creating the lite version.

Rather, I think we can say based on those datapoints that for their design, performance scales superlinearly with cost. Not surprising given fixed costs!

#5The performance factor vs. torque vs. DOFs is the most silly thing as a licensed mechanical engineer I have ever seen. And I was around for Kony 2012.

Can you explain why to the layman?

#7Very cool! Open source robotics is something I always imagined to be a part of the future. Hope the idea catches on.

Depends on the relative market size for performance factor though. If 90 percent of the market is captured by a 0.14 performance factor then that extra in price could be put towards solving another problem.
