-The program worked quite well. The robot succesfully avoided obstacles registered by the ultrasonic sensor, and when approaching a corner it seemed like the robot was attempting to find a way around the obstacle by scanning from side to side by turning its body, increasing the angle for left-turns with each try. When we looked into the program code, we saw that this observation is correct albeit a little too specific: the robot increases its turn angle in the direction where it measures the largest distance to any obstacles - i.e. it will not necessarily be the angle for left-turns that is increased. Video 1 shows the robot avoiding different obstacles [TODO: grundigere beskrivelse af video]
