In this paper, Robot Two Wheels are developed further to improve performance or intelligence. A Robot Two Wheels is a robot that can move and balance itself on two wheels, maintain its position upright of the earth’s surface on a flat plane. The design includes the Arduino Mega 2560, accelerometer and gyroscope sensors, as well as proportional Integral Derivative (PID) control as the controlling method. Proportional Integral Derivative control is used to determine the magnitude of the DC Motor’s speed and rotary direction as the driver, based on the robotic body’s tilt angle to the surface of the flat plane. The angle of inclination is taken into consideration and the robot moves either in the forward or backward direction to balance itself. When operated, the self-balancing robot continuously rotates its motor in its efforts to balance at upright position. The self-balancing robot movement is not mapped to its range, where the robot will still move randomly to achieve balanced conditions. The concept of this paper is expand the ability of the robot to sense objects around it which is by adding an ultrasonic sensor as an object detector around it, including obstacles or walls around self balancing robots. Detection of obstructions by ultrasonic sensors will maintain the movement of the robot in the safe area to avoid the impact that can occur when the robot is trying to maintain balance.
The ship robot uses a pH meter sensor to measure the water acidity and LDR sensors for measuring water clarity. The measurement results will be sent directly using bluetooth communication. This ship robot is made with the aim to facilitate in doing research on pH levels and water clarity level To get accurate results required sensitivity and proper sensor placement. Testing sensitivity on ship's pH robot sensors by comparing two gauges to see the difference in measurement values obtained. Sensory clarity test by looking at the change in Lux value (Lighting Refraction) based on sensor placement distance. Lux value is the readable value of the smartphone to display the clarity level in the water. Sensory clarity test using 3 samples with clear category, somewhat clear, cloudy. Distance of sensor placement ranging from 1-5 cm. For acidity measurements, the SKU pH sensor: SEN0169 has an average accuracy of 0.06-2.33%. While on the measurement of clarity, the higher the value of lux then the higher the level of clarity and the lower the value of lux then the lower the level of clarity.
The infrastructure development is not equal to the consciousness of keeping it. In many areas, the destruction occurs before the development has been finished. One of them can be seen in Sekanak River restoration. Some parts have been damaged although the development has still be in progress. Therefore, an activity monitoring system that can monitor and give warning to the vandal is really needed. The system can be an alternative to prevent more destructions. However, due to the system will be applied in the public areas that is difficult to be reachable by the electrical source from the State Electricity Company, an independent supply is needed. This paper presents an analysis of the solar panel that can supply the system continuously. The analysis involves the calculation of the supply that can be used to switch on the system for 24 hours a day. From the experimental setting, it can be proved that the proposed solar panel design and construction has worked well. It can supply the total need of the system power of 200 watt for 24 hours.
