Torque/efficiency is still a big issue. A coworker and I put together all the math and specs for a robot which could "cook breakfast", just to see what a PoC would take. For anything approaching human arm levels of strength, in that form factor, you are looking at SWG servos. These are nominally 70-80% efficient, but that drops after a few thousand cycles, if you operate in higher loading regimes [1]. so cooling/maintenance is super important. Planetary gears are also not great efficiency-wise and are heavier. Force feedback is also super important and challenging. We just need like, synthetic actin :) Disney is actually working on that [2]. yeah it looks super inefficient but so were vacuum tubes before transistors. 1] https://eeepitnl.tksc.jaxa.jp/mews/EN/19th/text/206.pdf&ved=2ahUKEwiHkd2B57HnAhVZaM0KHU_xAKUQFjAPegQIAxAF&usg=AOvVaw2F4XHlavPrQQiyKJMZSuwt https://eeepitnl.tksc.jaxa.jp/mews/EN/19th/text/206.pdf&ved=... 2] https://studios.disneyresearch.com/wp-content/uploads/2019/03/High-Performance-Robotic-Muscles-from-Conductive-Nylon-Sewing-Thread-Paper.pdf&ved=2ahUKEwjG-oCP6bHnAhXBHM0KHeT7B4YQFjAZegQIBhAF&usg=AOvVaw1T86dwb46W3evrawujoK5n https://studios.disneyresearch.com/wp-content/uploads/2019/0...
