We made an actual stop light that works with LED's to represent light colors. Our requirements were that we had build an actual model, have a Terry Box, the push button has to be pushed to change the light from red to green when an emergency. We used Vex parts to build an actual model of the light. We used a green, yellow, and red LED to represent the lights. There was a line follower to detect the light level so the push button can be pushed for the light to go from red to green in the Terry Box.

We designed a toll booth gate that would open with the line follower being covered, and would be closed if the line follower was not covered. When the line follower was covered, the gate would open and the red light would turn green letting the car pass through, and when the line follower was not covered, the gate would still be closed and the red light would remain on. Some Materials we used were a Potentiometer, Line Follower, Red and Green LED's, a Motor, a Battery, and Vex parts to build the model. Some challenges we encountered were trying to get the code to work. Here is a video below showing you the details of the project..

we have three limit switches inside of our ealvator each one you use to get to the next floor.and a push button that calls the elavator back down. some challenges that we encountered were trying to get the limit switchs to work and getting the line follower to work.

Darya, Jannat, Anika, Nestor, and Anastasiia;Task:5, Grandma's Chair (Final Copy)

# data[].attributes.body
Our mission was 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 and ready. Our constraints are:

1) Grandma must go upward and down
2) The angle of the stairs has to be 30 degrees
3) The limit switch must be used
4) The line Follower must be used
5) The movement has to go from rotary to linear

Our mission was to design an elevator that grandma can sit on to ride up and down the stairs.
1.Switch mounted to the chair
2.Chair needs to go up and down
3.Always return to first floor when grandma touches the switch
4.Use line follower to tell when the chair is at the top and bottom of the stairs

Shuting, Evelyn, Sarah, Paul; Task 5, Freight Elevator 

# data[].attributes.body
We were employees at a VEX company and our mission is to built a freight elevator to deliver parts to various floors of the factory. Our constraints are...
1) 3 floors
2) Each floor must be 3 inches from each other
3) The elevator must include 3 limit switches
4) Each floor needs one sensor to detect the approaching elevator (we used the line follower)
5) There must be an additional sensor on the first floor (we added a bump switch to reset the elevator)

Mia, Leah, Sarah - Task 5 Granny's Chair

# data[].attributes.body
Granny is getting to old to go up and down the stairs without falling down, so our task was to create an elevator (or chair) that Granny could up and down the stairs on, with a press of a button. The constraints were...
1. A limit switch (check: we used a bump switch instead)
2. If the chair stops midway, always return to the 1st floor (Our chair does not stop midway)
3. Line follower sensors (we had trouble using them, so we did wait commands)
4. Mechanism that converts rotary to linear motion (check: a chain drive)
5. 30 degrees is the angle of the stair. (check)

We had to make a moving vehicle that can move 20 ft the fastest compared to other ones. The constraints were it has to be able to move 20ft, it has to have a bump switch, and it has to have 2 motors

Grandma's Chair Task #5  Jacques/Joshua/Joaquin

# data[].attributes.body
This chair is suitable for a grandmother to travel up and down the stairs. Our requirements consisted of the chair moving once the button is pressed, rotary motion being converted to linear motion, wiring limit switches, and Line Follower sensors determining whether the chair is at the top or bottom.Our red and green lights display where the chair is situated. The button on the back of the chair activates the movement of the chair. Our chain drive moves the chair along. The chair stops once it hits the limit switch at the top of the second floor.

Task #2
The original design problem was to create a drag racer that travels 20 ft using two motors. We met each constraint by putting both of our motors in the back of the car, making the car reach a 20ft distance and having four wheels.

For our project, we had to create a fully functional stoplight that used a sequence with the red, yellow and green lights. The stoplight had to have an emergency switch that stopped traffic to allow an ambulance or other emergency vehicle to pass through. We met these constraints by  building a stoplight using VEX parts and a cardboard.  The light runs a sequence of red, green, yellow and then back to red using VEX LEDs surrounded by tinfoil. The stoplight's cortex and wiring is  inside of a cardboard box hung on a stand made out of VEX parts. The USB cable connects the light to a computer to send the code. The ambulance has a cardboard frame built onto a VEX plate with wheels. The ambulance also features flashing yellow and red lights. The ambulance also has a USB to connect to a computer for the code.
