Please make sure that your Light Sensor is as close to the ground as possible without touching the ground and that it is perfectly perpendicular to the floor.

ULTRASONIC SENSOR See NXT folder on desktop/Robotics Engineering Vol 1/Reference/Building Instructions/Taskbot Attachments/Ultrasonic Sensor for an idea of how you can attach it. Please make sure that your Ultrasonic Sensor is perfectly parallel to the floor.

AND

TOUCH SENSOR See if you can figure out a sturdy way to attach the Touch Sensor. Please make sure that your Touch Sensor is placed on your robot so that it extends in front of your robot otherwise it will not be able to bump into anything.
