Day of Competition

Registration & Inspection

At this point of the competition, your robot will be inspected to make sure it complies with all of the rules specifically states in the VEX Robotics In The Zone Manual. Below you will find a link to the inspection sheet most competitions use, as provided by VEX.

Among the important points in the inspection:

  • Your robot will be checked with the VEX Sizing tool to make sure it fits in the 18“ x 18” x 18“ (length x width x height) rule.
  • The inspectors will check all metals to make sure none have jagged edges or protruding parts, as this may interfere with other robots (entanglement) or the safety of the people operating the robot.
  • Make sure you have the two team identification plates placed on the robot in the intended location. This is done to make sure that your robot doesn't extend over the 18”x18“x18” limit.
  • On the robot, there must be either:
  • * Ten (10) 2-wire motors and a pneumatic system (tank, piston, and tubing)
  • * Twelve (12) 2-wire motors and NO pneumatic system

At this point of the inspection, you'll arrive at a station where the inspectors will make sure the robot is operational. You will be asked to turn on the robot, connect it to its joysticks and run it. After, a VEX Competition Switch will be connected to your joystick to commence the autonomous. REMEMBER: Bring your joysticks and robot, charged and ready to go, to inspection.

Some competitions may test whether the motors have been “modified” by removing a limiting mechanism that stops the motor when it overheats. By removing this mechanism, the motor is pushed past its threshold once it overheats and it may subject the surrounding areas to overheat and light up. Thus, some competitions chose to test the motors by disconnecting any one of the 10 or 12 motors and connecting it to a separate microcontroller. That motor is then turn on and whatever part is connected to it will move. For example, a wheel will be turned on and the inspector will hold the wheel until the motor starts to overheat. Meanwhile, a multimeter is connected to check the output voltage of the motor and monitor its behavior.

Finally, you'll reach a station where the entire checklist is double-checked and signed by an inspector and a member of the team. Congratulations! Your team is ready to compete!
