Obstacle measuring car

A car with intelligent judgment function is designed and produced. The car has the following functions: automatic obstacle avoidance function; tracking function (driving according to the black track on the road); phototaxis function (finding the point light source in front and driving in place); It has the function of detecting the number of iron pieces placed on the road surface; it calculates and displays the distance traveled and the walking time, and can make sounds and light up. The work can be used as a high-end smart toy, or as a powerful application example for college students to learn embedded control.
