Today we are working on detecting the green squares and pushing the can out of the chemical spill area. We had a problem with detecting the squares on both sides and detecting the tin foil with only two sensors but we got around that by adding another light sensor in port one. We are still working on the problem of finding the can when it is in one of the corners and the ultrasonic sensor can’t detect it. We can’t set the sensor to detect objects further away because then it becomes too unreliable, so we are thinking of a way to get the robot to cover more ground while not exiting the green space.
