What is a Servo Motor?

All motors are essentially devices used to transform different types of energy into specifically mechanical energy. There are a tremendous amount of motors on the market today, each with their distinct approach to energy conversion and specialised uses in industrial and lifestyle products.
A servo motor is just one of the motors that has enjoyed enduring popularity in the mechanics industry. It is made up of four different parts: a position-sensing device (such as a potentiometer), a DC motor, a control circuit and a gear reduction unit. All of these parts work together to allow the servo motor to receive control signals which represent the sought after output of the servo shaft. The signals power the DC motor to turn until its shaft is in the right position. The shaft in this motor has a more limited rotation than those in regular DC motors, being able to turn a maximum of 200 degrees in each direction. The rotation of the shaft is determined by the position-sensing device, thus controlling the direction in which the DC motor needs to turn in order to arrive at the correct position.

A servo motor is distinct in that it has three wire connections: one wire connects to the power source, one wire connects to the ground and one wire connects to the control. For these motors to function, power must be applied from a constant source. These motor operates by drawing the current from the power lead. Because, as we have learned, servo motors contain a built-in rotation sensor, they are a very important motor for the achievement of movement in robotic technology. A servo motor can be used to facilitate life-like movement because it skillfully transmits information concerning the degree of the rotation of the motor on its axis which allows a robot constant awareness of the positions of its appendages. As well as being used widely in robotics, these are employed extensively in the operation of remote-controlled model boats, trains, aero planes and helicopters, as well as to control the movement of real boats and aero planes.
There is no single kind of servo motor, but many different variations on this basic motor design that offer a large variety of attributes concerning strength, speed, break load, motion type, gearbox, size and weight. The demands of the industry and the budget available generally determine what will be the most appropriate type of servo motors for each application.

Hyundai Tucson was launched in India in 2004 and is one of the SUVs being marketed since then. The car is equipped with a powerful turbo charged CRDi engine that guarantees the performance and silence of a petrol engine. It has a seating capacity of 7, and is quite comfortable, which is an immediate attraction to customers. It has 5 manual type transmission gears that are not hard while shifting.

It includes loads of safety features like ABS system that helps shorten braking distance and the locking of wheels on wet or slippery roads, airbags and responsive front & rear disc brakes. Nevertheless, with all the safety features, one must also be prepared for sudden eventualities such as accidents or wear and tear. This causes repairs and eventually a financial loss too. That’s the reason why liability car insurance turns out to be a necessity.

According to the Motor Vehicles Act, 1988, it is mandatory for every vehicle owner to take a liability car insurance policy. This would cover the amount, which the owner becomes legally liable to pay as damages to third parties as a result of accidental death, bodily injury or damage to property.

There are two kinds of auto insurance: third party insurance and comprehensive insurance. Sometimes the damage caused by accidents can be quite severe and the financial loss incurred could be very high, hence third party auto insurance may not be sufficient. In such a case comprehensive auto insurance including vehicle maintenance policy becomes handy as it covers expenses made for third party damages and injuries. It will pay out in the event of the Hyundai Tucson being stolen or damaged in a fire or other natural or man-made calamity. It also pays for any damage to the vehicle in accident, regardless of who was responsible for the accident. When a car owner buys insurance with such coverage, he is also free from the obligation to pay for the medical expenses that arise in an accident. Though he is prone to legal action, he is spared the expense of legal procedures.

When compared to third party insurance, comprehensive insurance covers almost all kinds of risks. Thus, it is important for you to buy a suitable teen auto plan for your child before you gift him a Hyundai car. With the right auto insurance, Hyundai Tucson owners can set out for an adventure with nothing else on their mind.

Young drivers who take risks on the road have a greater risk of mental health problems

Young adults who involve in risks while driving are more suseptical to experience psychological distress, including mental health problems such as anxiety and depression reveals research published ahead of print in Injury Prevention. Teenagers are good at talking on the phone. But they're not such good drivers -- especially if they're trying to do both at the same time.

Teen drivers dangerously divide their attention

Most young drivers are engaged in distracted driving even though almost all are aware that it's dangerous.

Almost nine out of 10 young drivers (86%) have driven while distracted, even though 84% say they know they shouldn't. More than one-third of the young drivers said they had nearly crashed because of their own or someone else's distracted driving.

Young drivers have more accidents and are more likely to be involved in a accident in which someone dies than older drivers, and risky behavior is known to contribute to crashes involving young inexperienced drivers.

Psychological distress, such as depression and anxiety, has been linked to uncontrollable behavior in teenagers, including unprotected sex, smoking and high alcohol consumption. World researchers have therefore started out to find if there was any similar link between psychological distress and risk taking by young drivers, like speeding, not wearing a seat belt and using a mobile phone while at the wheel. Studies show the youngest drivers have the highest crash rates and highway accidents are the leading causes of death for people ages 15 to 20.

Researchers in Queensland, Australia requested 761 young fresh young drivers to fill out an online questionnaire to assess their psychological distress and their normal driving behavior. The young drivers were aged 17-25 years and had a provisional (intermediate) driver's license which entitled them to drive unaccompanied.

Psychological distress alone was found to result for 8.5% of the supposed risky driving behavior of young drivers. The distress level was greater in women than in men; 9.5% of the variance in risky driving could be explained due to psychological distress in women compared with 6.7% in men.

The authors suggested that similar research could be used to identify young drivers who are most at risk of psychological distress and therefore causing a greater accident risk on the road through risky driving behavior.

"Young drivers presenting to medical and mental health professionals could be screened for current psychological distress, particularly if they have incurred injury through risky and unruly behavior," they quoted.

These drivers should be targeted with specific road safety countermeasures and efforts should be made to improve their mental wellbeing by monitoring them for signs of depression and anxiety at an early stage.
