Flobi Robot, Flobi

Flobi Robot is a smart head robot that can display primary and secondary emotions in a human-like way, to enable intuitive human-robot-interaction. Flobi has high-resolution, wide-angle stereo vision, gyroscope motion compensation and stereo audio. The head is self-contained, and has 18 actuators, sensors and control boards. The core structure provides anchor points for the mask, the sensor and the exterior expression elements; the eyebrows and lips.

Flobi has a tendon-mechanism, allowing placement of the motors away from the joints.  Most of the motors are placed on a circular support in the middle of the head, to achieve an even weight distribution. The motor axis is connected to a triangular wedge, that converts rotary motion to a pull and push motion, driving a bowden cable. The motors used in the upper head are Maxon type 203893 with gear ratio 67:1. These motors are also used for eye-motion but here, static levers are used to actuate the eyes.  All motors are equipped  with encoders for velocity control.
