Self-Guiding Bullet

A team at Sandia National Laboratories, led by Larry Shipers, has designed a new kind of 50-caliber bullet that is dart like in shape. It is a non-spinning, computer aided bullet that has an ability to increase the accuracy by as much as 90%.
The bullet has an optical sensor at its tip and four tiny motorized fins that are able to change the angle. As a shooter determines the target by a laser dot, the optical sensor locks it down. The bullet also has an eight bit processor operated by a battery. This processor uses a control logarithm to steer the bullet to adjust its path. The processor works by 30 times a second to increase the accuracy.

A standard firearm with a smooth-bore barrel can eliminate the spinning and produce the required result by shooting this bullet. it can increase the accuracy, save money and reduce collateral damage.
