KemaState is a class for saving robot status. It records sensor values, speed and rotation, if any. In the sketch for Arduino Mega, two variables of this class are used: current and previous states.

Wheeled robot arduino

KemaIR - class work with infrared sensors. These sensors trigger at a certain distance, in this case just below the plane on which the robot wheels are standing. If at least one is triggered, then the robot stops.

KemaUS is a class for working with ultrasonic sensors. If the distance to the obstacle is more than 30cm, the robot moves forward, the light on the LED indicator is green. At a distance of 15 - 30 cm - it stops, the LED indicator is yellow. When the obstacle approaches less than 15 cm - the robot travels back, the LED indicator is red.

Simple class to work with crash sensors.

KemaMem is a robot memory class. At each iteration of the loop () , the speed and rotation data are written to the memory, for a total of 3 seconds. The meaning of this memory is to roll back, i.e. If the robot rode forward, then it rolls back, etc.

Crash sensors are mounted on robot.

My wheeled robot is turning around. The power of new motors is enough to do it.
