These effects happen in this order at the end of each register:

BATTERIES: If your robot ends a register on a battery space, you gain 1 Energy. Advance your Energy Tracking Cube 1 space up on the track on your player mat. Each robot can store a maximum of 10 Energy at a time. If you already have 10 Energy and would gain more, nothing happens.

CHECKPOINTS: You must reach the Checkpoints in numerical order to win. If your robot ends a register on the Checkpoint that matches the number to the right of your Checkpoint Tracking Token, move it 1 space to the right on your player mat. Your token will now be on the Checkpoint number you currently occupy: When you reach Checkpoint #1, your token will move from Start to #1 on your player mat. You now need to reach Checkpoint #2 (unless the race course featured only a single Checkpoint).
