First racing the wall, stenobot did it !

First try to race the wall, unsuccessful yet(

My current project - wall racing wheeled robot.

FPV video of my wheeled robot.

I've mounted an action cam on my wheeled robot. So will try to shoot some fpv videos soon.

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

New motors and 2 additional batteries are installed on wheeled robot.

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.

KemaLED is a class for controlling a full-color LED indicator. Blinking means radio control mode, constant light - robot mode. There are three colors: Green - the robot rides ahead (no obstacles); Yellow - the robot is stopped; Red - the robot rides back. The blue LED means a rollback from memory.

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.

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.

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.

Simple class to work with crash sensors.

Crash sensors are mounted on robot.

I've added NiMh batteries for motor feeding. Li-ion 650mA is used for arduino and other electronics.
