Electrostatic discharge events (aka �ESD events�) have the potential to disrupt the normal operation of competition robot.   As a robot moves across the floor of a FIRST Tech Challenge field, the robot tends to accumulate positive electrostatic charge on its metallic frame due to a physical phenomenon known as the triboelectric effect .   The charge that builds up on the frame can be significant (on the order of 25kV or higher).   If the charged robot touches another conductive object (such as a metallic game element, the perimeter wall, or another robot) that is at a different electrostatic potential value, an electrostatic discharge can occur and current will flow from one conductive body to the other as the charges equilibrate. These ESD events can disrupt, or in rare cases, damage the Control System electronics on a competition robot.   Charge is transferred from wheel to floor due to the triboelectric effect. Electrostatic buildup is a problem in robotics compet...

There are many ways teams need to get prepared for the upcoming season. Of course, teams first need to register and order their robot kit. At FIRST� Tech Challenge, we are anxiously waiting to share with you the official game challenge for FIRST� RELIC RECOVERY SM . Make sure you�re part of the big announcement by attending Kickoff event in your area or tuning into the game and season page Saturday, September 9 at 12:00 P.M. EDT. After the game challenge is announced, it�s time to prepare your team!      Complete team registration and required screenings      Order robot kit and parts Now the adventure really begins! Teams now get to strategize ways to complete each task in the game challenge, and work together to design, program and build. One of the best ways to help your team prepare, is with an official FIRST� RELIC RECOVERY SM field. As resources vary for each team, we have provided several options for teams to access field and game elements for prac...
