Abstract: Various embodiments of the present technology generally relate to robotics. More specifically, some embodiments of the present technology relate to an integrated system design for a mobile manipulation robot with socially expressive abilities. Some embodiments provide for a robot comprising a socially expressive head unit. The head can have at least two degrees of freedom created by a motor with a planetary gear box and a servo. The motor can be connected to a shell via a support that allows the shell to tilt up and down upon activation of the motor. The shell can include a camera housing configured to receive a camera which can be attached to the support. The motor can be mounted on a rotatable shaft controlled by a servo causing the head unit to pan.
