Arms are key mechanisms used in FRC robots to lift, position, or manipulate game pieces. They provide controlled motion through one or more rotational joints, allowing the robot to reach scoring locations, interact with field elements, and adjust game piece orientation. Understanding the basic concepts behind arm design helps team members think about reach, stability, and how motion paths support strategic gameplay.
This test focuses on the core ideas behind FRC arm mechanisms: how rotation and geometry determine reachable positions, how loads affect motion and control, and how design choices influence consistency, speed, and overall robot capability.
If you are familiar with basic FRC robot systems, this test should take about 5–10 minutes to complete.
