"What a robot says and what tone of voice it uses can determine whether the user will find it engaging or boring, intimidating, or encouraging..."

Robots, from vacuum cleaners to factory robots, have become an ever growing aspect of our home and work lives. When it comes to robots, the toy industry has been way ahead of everyone else. The first toy robot, "Robert the Robot," was developed in Japan in 1954, 65 years ago.

We have certainly come a long way since that time, with robots taking up shelf space in toy departments and stores. Yet, there is still a lot to learn about how to make robots that reward play with more than cool sounds or life-like movements.

The article goes on to make these key points:

Personality

The robot's personality is a critical component in how it matches with the end-user. The research has found that extroverts work better with extroverted robots, and introverts do better with introverted robots. That tells me that the robot should adjust its personality based upon its human interaction. Short of that,  the robot's creator may want to offer alternative personality settings. 

Imperfection

It seems that a perfect robot can be off-putting. Studies found that when robots have a problem and owned it, users were empathic and in some cases, acknowledged their imperfections. The challenge is to determine what the right level of imperfection is.

Surprise

Predictable robots are boring. Robots that occasionally do or say something out of the norm are charming. At least that is what the studies tell us.

Over-promising

Robots that look too human often disappoint because......they are not. People seem to find the gap between promise and performance to be disconcerting. So, don't try to make the robot look or sound exactly like a human being but create a look, though not human, that is endearing and engaging.

Bottom line, build a better robot and the world will beat a path to your door.
