Taking FIRST to new levels

Electronics Level 3

The Electronics Level 3 badge is designed for participants to demonstrate their knowledge about the wiring, sensors, schematics, motors, motor controllers, control system components and power used in the FIRST Robotics Competition.

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.  We use Schoology as the management tool for the portfolio submission.

Follow these directions to be considered for Electronics Level 3 credit:
1.  Create a user account as a student on Schoology.
2.  Enter access code: KQKV2-M5PK3
3.  Complete the signup for Schoology. Note: if you already use Schoology, use your existing Schoology account and click the “Join” option in the Courses section. Enter the access code above.
4.  Click on the Assignments folder to access the topics and items.  Click the Submissions button to upload your evidence for consideration.

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

Wiring

Explain how wire size impacts resistance and current flow. Select the correct and FRC legal gauge wire for the application.
Explain the strengths and weaknesses of the following wire join techniques: splice, butt-joint, crimp, wirenut. Select the correct and FRC legal join technique for the application.
On a FRC-size robot, organize, secure, strain-relief and label all wires.

Sensors

Attach a sensor to the robot or robot subsystem and wire the sensor to the control system.

Schematics

Create a basic schematic for a robot subsystem.

Motors/Motor Controllers

Explain the wiring of controls for PWM or CAN control, including type of wire, voltage and the output signal.
Wire a PWM or CAN control to a robot subsystem.

Control System

Connect all control system components and verify connectivity.

Power

Create a battery charging, rotation and tracking system.
Create or modify the mechanism to secure the battery in the robot.
Demonstrate how to properly handle a battery.
Demonstrate the procedure, using the necessary tool, to check if the chassis is electrically isolated.
Define the procedure to correct a situation when the chassis is found to be electrically charged.
