- Please written by computer source Build the code of an Arduino platform program that controls the movements of a robot. This robot has two infrared sensors, which make it follow a trajectory drawn on the ground, and two motors, one for each drive wheel. When the sensors detect the need to adjust the route, the engines must be manipulated in order to carry out the adjustment. For example, if the robot is veering to the left, the robot must move to the right until the route is fixed. For this, the motor on the right must be reversed (rotating backwards), and the one on the left must remain on (rotating forward). When the route is right, both motors must be turned forward so that the robot continues to walk straight ahead. The robot has an activation button that, while pressed, the robot must continue moving and, if released, must stop the movement. The sensors work as follows: the sensors are digital and Boolean having only value 0 and value 1; the value 0 means that the sensor did not…Class UserPigPlayer java.lang.Object UserPigPlayer All Implemented Interfaces:PigPlayerpublic class UserPigPlayerextends java.lang.Objectimplements PigPlayer UserPigPlayer - text interface to query user for roll/hold decisions Constructor Summary UserPigPlayer() Creates a new UserPigPlayer instance to allow user play via standard inputOutput format: Print an instruction line "Enter nothing to roll; enter anything to hold."
