I would extend the ez with parts that enable it to show basic awareness of its surroundings. Ideas could be temperatre sensor, CO2 sendor (when the air in a room is ''good'' or ''bad'' and give alarms when there is too many ppm CO2, such as from a heater or fire), water-sensor so that it would stop in front of a poodle, noise sensor to know when it is loud or quite (good in shools
), light sensor and a basic built-in clock.
