2. • 4mx4m ring
• avoid the blue balloons
• pop the red balloons
• 3 min countdown

4 meters

3. The hardware is consisted from different modules like:
-nxp LPC1768 microcontroller design board
-one dc motor driver using L298P H-Bridge
-power module to supply the system and H-Bridge
-a radar module using two ultrasonic sensors
-one servo motor to destroy the baloons
- two DC motors mounted on a gear mechanism to
increase torque
Color sensor using TCS230 circuit

4. • the radar scans 360 degrees
• the position and distance of the obstacle is known
• we use a matrix system to map the places we navigated

6.  When the car moves to the balloon it also
memories the distance and the route to it so it
will never cross the same route again.
Considering that the balloon
is marked with X the route
which the car will travel will
be as is marked.
When reaching to the balloon
the car will stop in the square
matrix before the square of
the balloon, so the sensor
would recognize the color of
the balloon
