Developer builds expressive robot head Ecko using a phone and a robotic arm
1 reports · 1 sources
Developer No_Quail6685 built a prototype expressive robot head named Ecko using a Galaxy S10 phone paired with a borrowed RealMan robotic arm. The prototype is not a complete humanoid robot: the phone displays animated eyes and provides the camera, microphone, and speaker; ARCore facial landmarks are drawn within the eyes; a Mac backend controls the arm's movement and drives a Gemini-powered conversation, while displaying real-time joint telemetry in a digital twin. According to the developer, facial following only works within a limited range; the first movement stopped after about seven seconds due to a sign error, and this failure was kept in the build video.

A developer built an expressive head prototype, Ecko, using a Galaxy S10 paired with a RealMan robotic arm; it is not a complete humanoid robot. The phone provides animated eyes, a camera, a microphone, and a speaker, with ARCore facial landmarks drawn inside the eyes.
