- amelius 4y agoIt's $750 per DOF. Which is indeed quite expensive. Especially considering that this is AliExpress.
- sigmoid10 4y agoI have a fully articulated quadruped here and it cost like $15 per DOF (excluding the control board), which is pretty much the price of a small servo. I bet if someone wanted to, they could make a humanoid like this for under $1000. The problem is that there's no market because control algorithms are already pretty wonky for 4+ legs. Two legs is just too unstable, even if you just want to ply around with it.
- amelius 4y agoIt looks like this is the servo they used: http://en.robotis.com/shop_en/item.php?it_id=902-0124-000 http://en.robotis.com/shop_en/item.php?it_id=902-0124-000
- sigmoid10 4y agoIf that's true than it is insane. These things pull almost three amps at max torque. Now assume you need at least 14 of those. You probably never see them running for more than 20s in the video because they just run out of battery.
