A robot is placed in the middle of west wall, facing east, of a square arena with walls on all sides as shown below. A black strip is drawn from north to south in the arena. Each grid in the arena drawing represents a distance of one second travel of the robot. Trace the NXC program and draw the paths the robot travels.//Hardware: a touch sensor mounted on the front bumper and connected to SENSOR_1.//a light sensor also mounted in the front and connected to SENSOR_2.//OUT_C is used to control the left motor and OUT_A is used to control//the right motor. Assume that when the robot makes a 90 degree turn, it makes a perfect 90 degree task main() {int i; SetSensor(S1, SENSOR_TOUCH); SetSensorType(S2, SENSOR_TYPE_LIGHT); SetSensorMode(S2, SENSOR_MODE_PERCENT); OnFwd(OUT_AC, 40); Wait(2000); for(i=0; i 40) OnFwd(OUT_AC, 40); Off(OUT_C); Wait(1600);//Roverbot takes 1.6 sec time to make a 90 degree turn do {OnFwd(OUT_AC, 40);} while (SENS0R_1 = = 0); Off(OUT_AC);}
