Electronics Level 4

0 Points

The Electronics Level 4 badge is the culmination of the Electronics badge series.  It is designed to aggregate the knowledge and skills learned in the first 3 badges and apply this knowledge to solve and troubleshoot problems.

This badge is organized into 6 topics. To earn the badge, participants must successfully complete all items in each topic and create a portfolio submission documenting all items.

Portfolios will be evaluated by experienced FRC adult members using a rubric-based evaluation tool.  Participants will receive feedback if any portion needs to have more detail or evidence.  The participant can compile new evidence and have the portfolio re-evaluated.

After earning this badge, the participant can choose to display the badge on the Open Badges infrastructure including the portfolio information.



Demonstrate how to troubleshoot a non-working electrical component on the robot or a robot subsystem.
Demonstrate a complete wiring inspection.  Explain the corrective actions needed to pass the electrical inspection at a competition.
Demonstrate or teach another participant how to join wires with the team’s standard operating procedures.
Create a layout of the components including the breaker, battery, power distribution panel, motors, motor controllers, robot signal light, radio, roboRIO,  voltage regulation module (optional), and pneumatic control module (optional).  Optimize the layout to eliminate interference with movement of the robot chassis and robot mechanisms.


Create a troubleshooting checklist for all sensors installed on the robot or robot subsystem.


Create a wiring diagram and corresponding wiring chart for the robot.

Motors and Motor Controllers

Create a troubleshooting checklist for motor and motor controller electrical connections.

Control System

Create a troubleshooting checklist for the control system components specific to a robot.


Describe what is happening chemically in a battery during a match and why the voltage of the battery changes during the match. Explain chemical reactions occuring during repeated recharging of a battery that leads to a truly dead battery
Create a data table listing robot/driving behaviors, the voltage and amps used. Use this table to predict voltage and amp hours of battery left after a variety of driving profiles. Explain when and why it might be beneficial to use larger gauge wire that that required by FIRST.
