Hard to pin down -- and be comparable to a human arm but I'm going off some of the fanuc models

In the low scenario, programming a humanoid robot costs no more than training a person

Tooling Costs 150005000
Note that system design and tooling costs are the same for humans and humanoids -- that's one of the advantages

Hardware costs (hand)10000010000
Shadow robot hands are 100k. Yes you don't need a fully human hand to do many tasks. But I suspect you do need one to replace a human in all things humans do!
22
Hardware costs (Humanoid)15000016000
Being extremely generous, I'm saying a humanoid in the limit 4* the cost of a single robot arm. Right now a uniteree robot that can actually do things is $150k and that doesn't include hands

According to this https://www.azorobotics.com/Article.aspx?ArticleID=361 Boston dynamics atlas uses a 3.7 kWh li-ion batter that lasts an hour so the robot is using ~3.7 kW. Industrial electricity prices are ~$0.0572/kWh
