Robot Completed

Provided is the picture of the entire robot assembled with all sensors and equipment to perform in the competition.

 

 

LDR Musical Instrument

Robet Vex Programming

Here is the Arduino with the new microcontroller tested.

Robot Fan

In order to blow out the flame, a fan was installed on top of the flame sensor.

Robot Ultrasonar sensor

The ultrasonar sensor is placed in front of the robot to read the distance between the objects surrounding it.  Most of the time, it is the wall that is navigating in the maze. The wire connects to the analog section of the microcontroller.

Robot flame sensors

In order to put out the flame, a flame sensor will scan the room to find it and allow the user to program the robot to drive towards it.

A 1.3K resistor is placed so that it does not burn out the sensor.  Cables are attached to the analog section of the microcontroller.

Robot Line Sensors

Line sensors can pick up the black tape lines that have been placed in the maze.  The robot will stop and proceed into the room with the encoder information.

It is located in the front and the bottom of the robot facing the floor.

Robot Encoders

Two encoders were placed side by side to control the count of the wheels.  This information would allow the user to tell the robot how far it should travel.
