Because our product is abstract, we need a robot to personify our brand. The robot "knows" which posts do well and it's the robot that suggests content to users.
We like the efficiency and sleek/sinister corporate feel of the original Verizon Droid commercials because our product will be aimed at Enterprise customers, but also appreciate the simplicity of the robots in Wall-E, NASA's Mars rovers, and the Androids in the films "Ex Machina," and "I, Robot"
We'd prefer something genderless to a strongly male- or female-gendered robot, but we still want it to have enough personality to be memorable.
We'd like something 3d, without being specific and detailed enough that we wouldn't be able to easily render it at small sizes.
That means any character doesn't need to be photo-realistic (can still be a cartoon), but we're hoping to avoid crudeness.
Please pay particular attention to the color scheme and robot-theme in the example image with the floating social-media icons on the blue/green gradient.
