The John Wayne Airport needs to place a toll booth gate at the exit of the VIP Parking Area. One sensor will be needed to open the toll booth gate, and one sensor to close the toll booth gate. A red light is on when the gate is down or moving (up and down).  You must use Brain screen to notify the user of the status of the code.

Bonus:

• Add a green light to indicate when the car can go through the gate.

• Use a line tracker to sense when a car is at the gate, this will make the gate open up. 

• Once the car has left the line tracker sensor area, the red light turns on and it takes 3 seconds before the gate closes down.

• Use a limit switch to model a coin sensor. Once the driver has inserted 3 coins the gate will open.

• Use potentiometer, gyro sensor or rotation sensor to sense the location of the toll booth gate.

Design Challenge

Grandma is too old to get up and down the stairs on her own. Your task is to design an elevator that Grandma can sit on to ride up and down the stairs. Grandma needs to have a switch that is mounted on her chair to start the ride up or down when she is settled in and ready.  You must use Brain screen to notify the user of the status of the code.

Bonus:

• If the chair stops midway, always return the chair to the 1st floor after Grandma pushes the button.

• Use sensors to determine when the chair is at the top and bottom of the stairs.

Design Challenge

The Jibboom Street Bridge, across the Sacramento River within the city Sacramento, is a 1931 steel truss swing bridge. It is old and needs to be replaced. You team is to develop a model of the replacement bridge. You must design, create, and program a working model of this swing bridge. The bridge will allow cars to cross the river when it is in the closed position and will allow boats to pass when it is in the open position. This a heavy bridge, use a mechanism to increase torque. You must use Brain screen to notify the user of the status of the code.

Bonus:

• Use LEDs to signal when cars must stop and when it is safe to drive across the bridge.

• Use more LEDs to signal when boats must stop and when it is safe to sail through bridge opening.

• Use a potentiometer, gyro sensor or rotation sensor to sense the location of the bridge.

You must design a robot that when a pushbutton is pressed will pick up and place parts using the claw end effector. At one end of its travel, the arm will pick up a manufactured part. At the other end, it will drop the part into a bin, return to the starting point to pick up another part, and so on. Sketch your solution on the lab sheet in the mechanical engineering section and label all sensors and motors.

You must work with the mechanical engineer and computer engineer to wire the appropriate motors and sensors to the microcontroller. Complete the wiring diagram on the lab sheet.

While the other engineers are busy working, you must write a program that will control the robot. Once the program has been started, the robot will move to the pick-up point. A sensor will signal the robot to stop and pick up the part using the claw. The robot will then move to the opposite end of its travel where it will drop the part in the bin. The robot will repeat this process every time a pushbutton switch is pressed. Open the PLTW Template and Save As PickPlace to your directory. Complete each section:
