how to control your robot
How to control your robot?
  • For Vex, we have two ways,
    • Remote Control
    • Programming Logic
the vex controller
The Vex Controller

The Vex Controller Board

The Vex Controller is the brain of the

Robot. All of your inputs and outputs

go through this controller.

remote control1
Remote Control

Signal Reception

The vex RF Receiver Module allow the robot to

receive transmitted signals. Reception begins

when a radio signal reaches the receiver’s antenna.

remote control2
Remote Control
  • The Vex Micro Controller coordinates the flow of information and power on the robot. All other electronic system components must be connected to the Micro Controller in order to function.
  • Control Configurations
programming logic
Programming Logic
  • Easy C
    • Easy C is a programming language that you will use to tell your robot what to do.
    • In Easy C, programs are written using icon-based code, but the interface includes a window that displays the program in a text-based format as well.
sensors
Sensors
  • Why does a robot need sensors?
    • The controller need additional information in order to make right decisions
    • The sensors are used to get these information.
    • There are different kinds of sensors, for example, touch sensors, light sensors, line follower sensors, optical shaft encoder, ultrasonic sensors

Sensors defined
  • Sensors convert physical phenomena into readable electric signals.
  • Also known as “transducers.”
vex sensors
Vex Sensors
  • Bumper switch sensor
  • Limit switch sensor
motors
Motors
  • Motors get their power from the batteries.
  • motors convert electrical energy into mechanical energy
  • Connected to the controller.
vex motors
Vex Motors
  • Motor

spinning either forward or backward at a controlled speed.

  • Servo Motor

Can be directed to turn to face a specific direction, rather than just spin forward or backward.
