1. Radio controlled vehicles
BY: STEPHEN POLIDORO

2. -FIRST REMOTE CONTROL CAR WAS MADE IN THE 1940’S
HISTORY OF THE REMOTE CONTROL CAR
-FIRST REMOTE CONTROL CAR WAS MADE IN THE 1940’S
-THEY WERE SMALL NITROMETHANE-POWERED ENGINES
-THE CONTROLER WAS ATTACHED TO THE CAR BY A TETHER
-THE CAR WAS FAST BUT ONLY WENT IN CIRCLES BECAUSE OF THE TETHER

3. FIRST COMMERICALLY AVAILABlE MODEL WAS THE FERRARI 250LM in 1966

4. 1970’S EARLY 1970’S - NITRO OR GAS-POWERED CARS WERE INTRODUCED
LATE 1970’S
- MECHANICALLY SIMPLE ELETRIC CAR MODELS WERE CREATED
-ADDING SUSPENSION CREATED FIRST OFF ROAD REMOTE CONTROLLED CARS

5. TODAYS REMOTE CONTROLED CARS
-FASTER
-MORE DURABLE
-IMPROVED TECHNOLOGY
-BRUSHLESS MOTORS
-STRONGER BATTERIES
-QUIETER MOTORS

6. HOW DO REMOTE CONTROLLED CARS WORK?
-THE TRIGGER IS THE MAIN CONTROL UNIT. PUSHING OR PULLING TRIGGER OPERATES THE CAR.
-WHEN THE TRIGGER IS PULLED A CIRCUIT IS CLOSED. THE RADIO SIGNAL IS TRANSMITTED
TO THE CAR AND IT MOVES DEPENDING ON TRIGGER MOVEMENT.
-THE REMOTE ACTIVATES THE CARS MOTOR WITH ELECTRIC PULSES WHICH MAKES THE CAR MOVE
IN ANY DIRECTION THAT THE OPERATOR CHOOSES.
-THE ANTENNA IMPROVES THE WORKING RADIUS OF THE CAR
-THE FIRST MOTOR TURNS THE FRONT WHEELS
-THE SECOND MOTOR IS FOR: DRIVE, FORWARD & REVERSE
-THE LOWER CHASSIS AND SHELL TOP ARE THE SKELETON OF THE RC CAR.
-ALL ELECTRIC AND MECHANICAL COMPONENTS ARE HELD IN THE LOWER
CHASSIS. THE BATTERY SLOT CARRIES THE BATTERY WHICH IS THE POWER SOURCE

7. YOU TUBE DEMONSTRATION

8. ANTENNA CIRCUIT BOARD 2 MOTORS BATTERY SLOT
THE RC CAR HAS FOUR MAJOR COMPONENTS
ANTENNA
CIRCUIT BOARD
2 MOTORS
BATTERY SLOT

9. EXPERIMENT MATERIALS NEEDED TO TEST HYPOTHESIS: -REMOTE CONTROL CAR
DO DIFFERENT ITEMS BLOCK RADIO FREQUENCY? I WILL WRAP MY REMOTE
CONTROLLER WITH SEVERAL ITEMS TO SEE IF IT EFFECTS IT’S FREQUENCY.
MATERIALS NEEDED TO TEST HYPOTHESIS:
-REMOTE CONTROL CAR
-REMOTE CONTROLLER
-NEWSPAPER
-ALUMINUM FOIL
-RUBBER GLOVE

10. PERFORM
EXPERIMENT
NOW!!!!!

11. TEST RESULTS/ CONCLUSION
DID ANY OF THE MATERIAL INTEFERE WITH THE REMOTE FREQUENCY?
