| dc.description.abstract | Sprayer is commonly used in agro-chemical aplication in form of a mist. However, the exposure of agrochemical to operator on operating sprayer potentially causing risk to operator health. The objective of this research was to design a web-based control system for unmanned sprayer in order to improved health aspect of operator. Mini electric car was modified into web-based controlled was used as model for this research. Maximum range of radio control was 55 m and maximum range of web-based control (Wifi) was 110 m. Therefore, web based control was chosen because it has wider range. The average forward speed of model was 31.04 cm/s with 1% of slip for left rear wheel and 2% of slip for right rear wheel. The average turning radius of model was 210.4 cm for turning right and 290.9 cm for turning left. Controlling test conducted at straight path, turn right, and turn left with 3 kinds of different camera angle i.e. 72o, 77°, and 90°. According to data analysis result by using ANOVA could be concluded that camera angle significantly affected on controlling straight and left turn, but didn’t significantly affected on controlling turn right. The difference in significancy was due to the model just using motor in the right rear wheel for moving so the model tends to moved towards the left. | id |
