Supplement Restraint System is additional safety equipment in a car. Such as airbags and seatbelts. Every person has a risk of having an accident while driving. This will lead to the risk of injury. Therefore, in a car should be equipped with Supplement Restraint System, such as air bags and seat belts. Air bags reduce the risk of injury when someone had an accident while driving. By having air bags mounted on a car, when the car suffered concussion, air bags inflate quickly in order to protect passengers clash with the interior of the car. The function of the air bag will be even better when teamed up with the function of the seat belt.Air bag will prevent passengers collided with a car's interior, and seat belt functions to hold the body of passengers being thrown forward. If both functions work well, it will greatly reduce the risk of injury significantly.
Robot line follower is a robot that is designed to be able to walk following the color of the line. Of course this requires basic knowledge of programming. In a line follower robot, we need a color sensor that will be used to detect line colors. Usually to distinguish between black and white. This color sensor, we can use infra red sensors, or can also use the LDR. Once we have a color sensor to detect the line, then we need the brain to make the robot can walk along the line. We can make it with an analog circuit, or with an IC that we will later fill with the program. To charge IC from line follower control, we can use arduino or by using Asembler programming. To learn this program, we must know the basics of logic. If we have the desire and sincerity in learning, to make a line follower is not a difficult thing. To make it easier we have a description of line follower, I took this from youtube video about lne follower. May be useful. link video : https://www.youtub
