The robot in service of the user
The novel design of Care-O-bot 3 represents an intentional move away from existing humanoid service robots. Instead, the robot has been given a functional design, outlining its abilities as a butler. This helps for the user to align his expectations with the actual capabilities of the robot and thus increases the acceptance of the robot. Furthermore, the role of Care-O-bot as a tool that is controlled by the human user at any time is underlined instead of presenting the robot as a technical or even equal version of the human.
