What is the collision sensor?

The

collision sensor is equipped with a mechanical device or a vehicle with what seems to be aware of its surroundings and the ability to respond to precipitation in this environment. Traditionally, rainfall sensors were used to detect or "sensing" of the actual collision between the vehicle and the subject of any kind. Especially in the area of ​​robotics, the term collision sensor , which means a device that will sense either a real collision or imminent collision. If the collision is scanned, the device may somehow signal warnings to prevent collision. The device specifically designed to prevent a collision is sometimes called the sensor avoiding a collision or anti-collective sensor to distinguish them from the collision sensor. A simple example is the flashlight switch. When the flashlight is on, two pieces of metal are pushed together. This completes the electrical circuit and current streams to turn on the light. This energy is similar to the energy that is used to signal the release of the airbag in VOchair.

A somewhat more sophisticated collision sensor is an electronic device that measures and quantifies the stimulus and converts it into a measurable electronic signal. Such a device in the car does not have to send a signal if movement or pressure does not reach a certain level of intensity or persists for a given time. In this case, the collision would have to have sufficient intensity or long enough to make an answer.

For example, when the car hits something, the pressure on the car's bumper is. Depending on the amount of pressure on the bumper, the impact will be detected by the collision sensor. The collision sensor then triggers an electrical current that results in a signal that triggers the airbag release. In other words, physical pressure is stimulus and the airbag release is a reaction. Some collision sensors can even send a signal to a remote road auxiliary service, such as onStar ™.

Collision sensor can also be used for a number of practitionersof the purposes. Robotic vacuum cleaners, such as Roomba ™, use collision sensors to help them pass through the room. When Roomba ™ encounters a solid object, such as the leg of the chair, a pre -programmed reaction to the collision is launched, called a random walk. Just as it sounds, a random walk is a series of steps in a random direction or trajectory.
