Electrical

Wire it once. Wire it right.

A robot that works on the bench and dies in a match almost always has an electrical problem. These two lessons cover how power moves through an FTC robot and how to stop the mid-match resets that come from static, noise and loose connectors.

Lessons

Read, then check yourself

Each lesson ends with a short quiz. Nothing is saved or graded. Take it as many times as you like.

  1. 01 Electrical Systems Volts, amps and watts. The Control Hub's ports. How power gets from the battery through the fuse and switch to motors, servos and sensors. Why the robot is slower at the end of a match. 20 minQuiz
  2. 02 Electrical Gremlins Hub reboots, phantom sensor readings and Wi-Fi drops, and the habits that prevent them: isolate the electronics, ground them with an approved strap, add ferrite chokes, route wires cleanly, and look after your connectors. 25 minQuiz

  • 6 motors across a Control Hub and an Expansion Hub
  • 2 servos, including the continuous-rotation feeder
  • Pinpoint odometry and the built-in IMU on I2C
