Software

Robots are programmed in ArduinoIDE with C++. Programs for robots are similar, but not identical because one robot dynamically calculates the angle between it and the ball and then multiples it by a set value which in return is his angle of a attack, meanwhile, the other robot uses a hybrid system that also calculates the ball angle, but will either multiply that value or move in a fixed pattern depending on a situation is. He will move dynamically when the ball is in the front and statically when it is in the back. This way we have an attack-oriented and a defense-oriented robot for optimal play.
