1. 2. The above program will... a.Will follow the line b.Will avoid a wall c.Will find an object and get close to it d.Will follow straight lines and turns 1. Identify the problem in this program. a.The robot cannot change angles b.A sensor block without a wait block never works. c.The robot cannot begin with a move block on ‘on’ 3. In the above program portion for finding and picking up the can, what problem will the robot have in capturing the can? a.The robot will not close the arms b.The robot will be too close to the can c.The robot will keep moving while trying to capture the can d. The robot arms closing should be set on rotations Unit II Test DO NOT WRITE ON THE TEST!!!

2. 4. The robot is driving in circles. What could be causing this? a.A large motor is not connected. b.The robot did not see the black line. c.The second block is a turn block on ON. d.None of the above. 5. The best way to test the above program problem is to a.Insert a sound block after the wait block b.Remove the 3 rd and 4 th blocks c.Check the ports and plugs d.Change the second block to 1 rotation. e.Place the robot on the black line. 6. You are programming for the robot to ‘find’ the can. What would be the best thing to adjust to improve your success? a.Lower the power of the first block b.Increase the power of the second block c.Lower the distance on the third block d.None of the above 7. Identify the type of gears that these are: a.Worm gear b.Spur gear c.Beveled gear d.Multi-direction gear BLACK

3. 8.The image to the left is the ____________________ sensor. It allows the robot to _________ __________________________. a.Infrared, helps the robot measure height b.Ultrasonic sensor, helps the robot measure height c.Ultrasonic sensor, helps the robot measure the distance away d.Infrared sensor, helps the robot measure the distance away 9.Three gears are connected. Start to finish the teeth numbers are 15, 40, and 60. The first gear spins clockwise. Determine the gear ratio and the direction of the spin of the output gear. a.¼, clockwise b.3/2, counterclockwise c.4, clockwise d.¼, counterclockwise 10.The gear to the right with the arrow is called a ______ gear. Its primary purpose is to ________________________. a.Spur gear, change direction of rotation b.Spur gear, change the angle of rotation c.Worm gear, change the angle of rotation d.Worm gear, change the direction of rotation e.Beveled gear, change the direction of rotation 11. For the following gears 30, 25, 15, and 90 (in that order). Calculate the gear ratio. The first gear is spinning clockwise. What is the spin of the output gear? a.½, counterclockwiseb. 3, clockwise c.1/3, counterclockwised. 5, clockwise e. None of the above 12. This is the ______________ sensor. It can detect three different things. Which of the following can it detect? Choose all that apply. a.Detect proximityb. Detect motion c.Detect colord. Detect pressure e.Detect temperaturef. Detect infrared radiation g. Detect ambient lighth. Detect reflected light

4. 13. To use the gyro sensor in a program, it is necessary to begin the program with... A. B. C. D. None of the above 14.In order to program the robot to capture the can using the medium motor, what specifics are needed? Choose all that apply. a.Program on secondsb. Program with negative power c.Program -1 rotationd. Program with move tank e.Program with positive powerf. Program with degrees g. Program with +1 rotation 15 - 19. In order to have the robot navigate from capturing the can to bringing the can to the landing zone, write out program blocks that will succeed in doing that. Where values from the mats are used just describe how they are determined. (The robot has just captured the can... Now what?) Format for what you turn in must be detailed enough that I have all of the pieces needed to program from what you write. Items such as wait blocks or details on a block will cause you to lose points.
