Background
Nowadays, the product with artificial intelligence (AI) is very popular in daily life, because the AI technology brings convenience to human. For example, the application of face recognition can replace the keys of the doors, so some persons feel easier and comfortable in the pockets or bags. Some smart robots are designed for smart live in houses, therefore, some persons reduce the trivial housings to make life easy which is one of the purposes of many studies relative to AI.
The basis
A system named ˇ°little sunˇ± is a combination of Arduino UNO and LD3321 modules. The four-channel relay switch module was connected with pins of Arduino UNO and embedded under the cover of a base set of the heater. Three commands, namely ˇ°Higher temperature,ˇ± ˇ°Lower temperature,ˇ± and ˇ°Stop,ˇ± were programmed. The voice commands were arranged to sound randomly to ensure comprehensive testing. The SNR of the command voice in a peaceful home is typically more than 10 dB. In 82 tests, the proposed device successfully recognized 80 voice commands at the first command. Thus, the success rate (SR) was 98%.
This study based on the prototype of ˇ°little sunˇ± improved the functions which include
(1) button or voice-controlled the radiator by smartphone APP;
(2) heat radiation power control, moving control and timing control; and
(3) feedback artificial synthesis voice for instruction, temperature feedback, and ultrasonic sensing for anti-collision. The improve the system is named as ˇ°sun magicianˇ±.
