Work Estimate: 40+ hrs.
Servo-controlled eyebrows should be added to the robot’s face, to allow for more facial expressions. This will require some mechanical work in attaching new servos and eyebrow hardware to the face. This will also take some software work, to add these servos to the ServoConfig.xml file, with the correct range limits and other parameters. Two servo outputs are still available on the Pololu controller, but a second servo controller might be required if the eyebrows require more than this (e.g. each eyebrow might use 2 servos: one to move the eyebrow up/down and another to change the angle of the eyebrow).
