APP
The display of APP is shown in Fig. These buttons are for the manual mode operation. The voice mode operation accepts the voice commands to control the ˇ°sun magicianˇ±. Firstly, the Bluetooth modules should be paired between smart phone and carrier. Finished the pairing, the voice mode can be done by clicking the voice button.
System integration
Under the cover of the electric heating radiator, the microcontroller connected with motor drive module for the movable carrier, timer for radiating, and active buzzer.HC-SR04 ultrasonic ranger was appended on the cover for anti-collision and DS18B20 temperature sensor module was in front of the radiator to sense the air temperature near the radiator and control the power of electric heating radiator.
Tests
For the manual mode operation, the corrective rates were almost 100%. Whereas, the voice controlled mode operation, all the commands (ˇ°Lower temperatureˇ±, ˇ°Higher temperatureˇ± and ˇ°Constant temperatureˇ±, ˇ°Forwardˇ±, ˇ°Backwardˇ±, ˇ°Turn rightˇ±, ˇ°Turn leftˇ±, ˇ°Closeˇ± and ˇ°Stopˇ± ) have been test for 100 times. The corrective rates were near 90%.
