Ameca vs Sophia

Ameca is a stationary full-size social humanoid from Engineered Arts (UK), listed at 187 cm, 62 kg, 61 actuated movements, with 27 DoF in head/face and 34 in upper body. It has 2x8MP eye cameras, binaural microphones, LiDAR, 50+ facial expressions, 70+ language support, and modes for interaction/conference/telepresence. Wikipedia documents public deployments including the National Robotarium and an ESA ambassador role. Video appearances exist but transcripts were unavailable. It does not walk, has no public price/runtime/battery, and no independent interaction benchmark

Sophia is a social humanoid robot from Hanson Robotics, activated in 2016, best known for media appearances and lifelike facial expressions. It has a patented Frubber skin, 83 total DoF per Wevolver spec (though overview says 74), 167 cm, 20 kg, and a wheeled base; around January 2018 it was upgraded with functional legs and walking. Its main evidence is in human interaction—over 60 facial expressions, many high-profile interviews, Saudi citizenship, and UNDP title. However, dialogue is largely scripted via decision tree, an insider ethnography says the robot is fragile and operationally unreliable, and no autonomous task demos exist. Hanson Robotics announced mass production plans in 2021, but no public price, named customer deployment, or independent benchmark was found
