Barboursville Middle March 17, 2003 There is a light sensor on the windmill at SENSORSCITY like the
one at the right. The dark and light sides of the circle show different light sensor
readings just as this measure car does with the black
dot on yellow. See the LEGO city from two views. Three turns of about 14 cm is about 42 cm. Two views of SENSORSCITY at Barboursville Middle March 17, 2003 Between Barboursville Middle and Village of Barboursville Elementary
there is real rail transportation. Village

repeat four times. We programmed another bot to send mail. The LEGO City can be teleoperated through Red Rover. When the Monorail reaches the right side the touch sensors reports
CONTACT. Touch shows 1 on the RCX and not touched shows 0. Have the Robot drive three feet while data logging light sensor
readings. Stop when touch.. Data shows seven rotations of the wheel. Let's check the circumference. 36 inches divided by 7 is a bit over 5 inches. Circumference of the Robot's tire is about 5 and a fourth inches.
