If these are changed. This is the code strip. On the bottom of each card. If these do match. The Light Sensor looks at each code square.
Deleting the file allows it to create a new file with the same name to update the content. Then RoboLock waits for someone to log in again.
Intruders refers to failed attempts to login. While the menu is displayed. First it aligns the card correctly in case the user inserts the card too quickly or too slowly then feeds the card in at a constant rate. When this is done. RoboLock waits for a card to be inserted. When the program is started. When Figure The secure card for RoboLock all the code squares have been read. The menu greets the user and lists the number of UMOs and Intruders detected.
The first is called Code Reader. When RoboLock detects a card. If these do not match. If the Light Sensor detects a white color.
These blocks write the text in the CardCode variable along with a w to a new Card Validation file and close the file. If the Light Sensor detects a black color. Create a My Block with these blocks and call it Card Reader.
These blocks write the text in the CardCode variable along with a b to a new Card Validation file and close the file. When you do this. The other blocks in the figure display Welcome User and the number ofIntruders. If the user presses the NXT Enter button. This makes the My Block exit when the Touch Sensor is pressed. These blocks display the number of UMOs detected by Sentry. If the NXT Enter button is pressed. This determines whether Sentry will be on or off. Once again. Another Light Sensor Wait block waits until a white color is detected.
These blocks delete the Card Validation file in case it was used in an earlier program and wait until a black color is detected. Then the remaining blocks put a b or w in the Card Validation file.
The Move block makes Motor B move the card such that the first code square is under the Light Sensor. After all but one of the squares have been read. The first three blocks repeatedly make Motor B move the card to the next code square and record the color in the Card Validation file using the Code Reader My Block.
The Text Switch block compares the Card Validation file with the correct code. Note that you need to put these blocks in the 0 condition of the Switch block. Note that these blocks should be put in the bbwwwb condition of the Switch block. When the My Block ends. If the code was correct. This code will run at the same time as the previous code so that Sentry can be on while RoboLock is waiting for a card to be inserted.
These blocks eject the card. These blocks wait for Sentry to be turned on by the value of the SentryStart variable being set to true.
The Loop Forever block will enable Sentry to be turned on and off as many times as desired. If it has. These blocks start motor C in the direction determined by the SpinDirection variable and test to see ifmotor C has turned more than degrees in a forward direction. If it is. The first two blocks determine if motor C has turned more than degrees in reverse. The next block determines if an object is in range of the Ultrasonic Sensor.

This variable will be used later to help Sentry detect only unique objects. Timer 1 and the ObjectUnique variable are used to help Sentry only detect unique objects.
The ObjectUnique variable is used to wait until the object leaves. Timer 1 is used to wait for five seconds after seeing an object before recording any more UMOs. This indicates that the current object has already been recorded. If no object is in range of the Ultrasonic Sensor.
Sensor steady and Switch blocks. When you feel the motor pulling on the card. When this happens.
The value of the SentryStart variable is wired into the Logic Loop block placed earlier to make it exit when Sentry is turned off. You can do this by turning the handle con- nected to the motor that rotates the sensor. Prosthetics is the science of making and fitting artificial body parts.
Suppose you lost your hand in a car accident. If you were outfitted with an artificial hand. The Hand Robotic hands come in many shapes and sizes.
Another application for a robotic hand is prosthetics. You can also put a gear on the outside of the turntable The Hand sits on your own arm. The Hand that we are going to create here is not as There is one issue to be aware of: If you hold the center complex as the human hand.
See the NXT-G program solves this problem. And it can keep revolving for as gear and rotate the fingers on the other side of the turn- long as your batteries last. If you the wrist to rotate degrees. It can also rotate a turntable allows a long axle to go through the inside of the degrees at the wrist.
This means that The Hand can only grab things that open or close slightly. The Hand can close and open its see the fingers slowly open or close. Figure on page shows how are wider than the space between the closed fingers. This happens because fingers to grasp and release an item. It will be added later when the parts are assembled into the final model. The worm gear will engage the gray gears and bring the fingers forward.
Insert the axle. When you attach the motors. Also, inserting the long black pins can be tricky. You might need to wiggle the motor a little to get the pins and holes to line up properly. Notice how the three wire guides hold the wires in place.
This is a good way to keep the wires from getting tangled on things when you use The Hand.
The program appears to be a little more complex than it really is. We basically have to make a few choices: Is the Touch Sensor pressed? Are the left or right arrows pressed?
This portion of the program controls the following actions: The Touch Sensor is pressed the wrist will turn ; the left arrow is pressed the wrist turns to the left. To toend run the forever. The Touch Sensor block controls which motor will be activated when you push the.
If the Touch Sensor is pressed, the wrist will rotate. If the Touch Sensor is not pressed, the fingers will open or close. Slightly rotate the center axle in the opposite direction. This prevents the fingers from open- ing or closing while the wrist is turning. The Touch Sensor is pressed the wrist will turn ; the right arrow is pressed the wrist turns to the right.

The Touch Sensor is not pressed you can control the fingers ; the Left arrow is pressed the fingers will close. The Touch Sensor is not pressed you can control the fingers ; the right arrow is pressed the fingers will open.
Try to design a finger structure that can withstand overtightening. No buttons are pressed. My Blocks will ment with it. A few suggestions for how you can modify both make the program easier to understand and are an excel- the structure and the programming are provided in the next lent programming skill you can use in other programs.
This is a result of using the worm gear it is slow but very powerful. When you have built and programmed The Hand. The Self-Parking Car is such a vehicle. Some luxury cars today actually have special sensors that enable them to do this.
Using an Ultrasonic Sensor. The Self-Parking Car clap of your hands. Just the same. You will not attach the beam to the car. Driving Motor to output port A. Place the car parallel to the first object as shown here. These 70 degrees must be measured from the point where the steering wheel is in the middle so that we can steer to the right point. When it finds one. This switch is continuously repeated and therefore.
One will make the car steer to the left. If this is not the case false. Before starting the program.
Step 1: Create a new document and place five blocks configured as shown in Figure Select an appropriate icon too. Now select all the program blocks that we added and turn them into a new My Block called Steer Left.
Delete the My Block from your work space so you can create the next one. Step 2: Place five blocks configured as shown in Figure We can check this by looking at the Rotation Sensor.
Step 3: Place three blocks con- figured as shown in Figure If the Rotation Sensor gives us a value close to zero. The configuration of the blocks placed in step 3 SPC: When the car is already moving straight ahead and the Steer Forward My Block is used. The value of the Rotation Sensor is wired into the Move block.
After this check. This block is different from the other two My Blocks you just created because now there are two possible direc- tions for the Steering Motor to turn—left or right. Now select all the program blocks that we added and turn them into a new My Block called Steer Forward. You must then delete the My Block from your work space so you can create the final program. Step 4: Place and wire four blocks config- ured as shown in Figure The configuration of the blocks placed in step 5 SPC: When the program begins.
It then resets the Rotation Sensor in the Driving Motor and moves on until it sees something the end of the parking space. Then it compares the value of the Rota- tion Sensor the distance traveled to 1. Step 5: Place four blocks config- ured as shown in Figure If this is greater than 1.
This will be demonstrated in steps 5 and 6. Step 6: The value of the Rotation Sensor is wired into the Compare block. Steps 7. Step 7: Place two blocks configured as shown in Figure If the result is false. The configuration of the blocks placed in step 7 SPC: Step 8: Place five blocks config- ured as shown in Figure This is accomplished by Motor block 8a.
A value less than 0. Before park ing. A value greater than 0. NOTE After the second object is detected. Step 9: You can now download the program to your NXT Brick. Remember to save your program. The configuration of the blocks placed in step 9 SPC: By combining these My Blocks Figure This can be done by programming it to steer exploration and back up when you clap your hands or by mounting the Ultrasonic Sensor in the front of the car to sense walls and other objects.
This is the final program that enables the SPC to park between two objects. In this chapter you learned to create the My Blocks that control the steering of the car. The program has been split in two here for readability. A Touch Sensor is used to detect if the grabber is lifted all the way up. Square objects. I have had the greatest Figure GrabBot success using a plastic cup with a diameter of about 2.
While you can pick up many things with the grab- ber. Whatever you use. The unique physical aspect of this robot is the grabber. Three objects left to right: Using the Ultrasonic Sensor. GrabBot spins around looking for the closest object. Attach the Brick subassembly as shown.
Then connect the Touch Sensor to input port 1, the Ultrasonic Sensor to input port 4, and the middle motor to output port A. If you have only sixteen of these available, you could leave out the bushings that would normally be placed on the outer side of the wheel axles.
Storing the lowest measured value along with the Rota- programming tion Sensor value works as shown in Figure GrabBot Is the sensor value less than lowest? In this program, we want to make GrabBot find, grab, lift, No Yes and When move we clap objects our around hands or themake roomanother while avoiding loud sound, walls.
This miniprogram rotates the robot degrees while the Ultrasonic Sensor looks for the closest object in range. The Rotation Sensor that is built in to the motor tracks the direction in which the object was seen.
When the scanning is complete, the robot turns to face the direction of the object. Program flow for the Search My Block Figure illustrates the scan. Note that in reality, the robot will make hundreds of degrees.
Then it rotates in the opposite direction and measurements instead ofjust four. Four measurements of the scan: H stands for Heading the angle the robot has turned compared to its starting point , and R stands for the value of the Rotation Sensor in the NXT motor. Create a new document. Declare two number variables, lowest and position, and place five blocks configured as shown in Figure Place a Loop block and a Switch block configured as shown in Figure This is the configuration of the blocks placed in step 2.
This is the configuration of the blocks placed in step 3. Place three blocks configured as shown in Figure This is the wire configuration in step 5. This is the configuration of the blocks placed in step 4. The tab under X false is empty. Wire the blocks as shown in Figure NOTE The wire between blocks 3b and 3c and the wire between 3c and 4a are two separate wires. This is the configuration of the blocks placed in step 6. This is the wire configuration in step 8. This is the configuration of the blocks placed in step 7.
Now select all the program blocks that we added and turn them into a new My Block called Search. This is the configuration of the blocks placed in step 9. When it has traveled this distance.
After this. Save the program and name it GrabBot. Then the robot will turn around and grab and lift the object. Then place five blocks configured as shown in Figure The output value of the Math block is wired into the Move block. This is the configuration of the blocks placed in step Step Place four blocks configured as shown in Figure This value may vary for your floor because of a different amount of friction.
NOTE wooden Blocks so to11d my floor point Motor and this the 11e is block grabber amake degree 11ethe toward is configured robot the turn spin object. The best way to find the right value is to run the finished program and modify the value until it works correctly.
Place two blocks and a Loop block configured as shown in Figure To program this behavior. Then replace the Ultrasonic Sensor block block 3b with a Light Sensor block. To improve steering and maneuverability.
Two stabilizers act as training wheels to prevent the Bike from falling over. To maintain sym- metry and balance. An array of worm gears. The Bike. Plug the motor on the left side of the rear wheel into output port B. The Touch Sensor should If you deviate from these instructions. Configuration of blocks for initialization that await a Touch Sensor press and initialize variable The program then begins executing the two parallel beams repeatedly. The following simple program will make your Bike run and independently—it avoid objects.
If an obstacle is detected. Configuration of blocks that control the random steering sequence Figure At the end of the sequence. It is initially set to 0 forward.
