Bobby is a smart speaker robot with rotatable touch screen. With Bobby's facial recognition technology and nearly 360-degree rotation body angle, there will be no dead corners when monitoring the home environment. Also when non-family members are being detected under the Security Mode, an instant notification will be sent to the mobile App. Bobby is able to connect to most of the IoT devices though Bluetooth as well. Therefore, based on the change of weather, high blood pressure, rapid heartbeat...etc., Bobby can automatically turn on the appliances and send alert notifications to remind to measure the blood pressure or take medications.
