LGT-01: Lights - colour rules and a flash per shot

low prioritySimulator or real robotabout 20 minLights

• Your robot needs: Light (goBILDA RGB or REV Blinkin).
• Starter bots that fit: none (it needs parts the starter bots do not have).
• Library version: v0.17.0 or newer.
• The docs it tests: Lesson 9: A shooter, a camera and a turret (for robots that shoot), Robot module (the robot in five files).

Why

A light lets the drivers see the robot's state without looking at the Driver Station. The rules must pick the first true one, and the light must never change faster than 5 times a second (game rule R202 J).

Safety

• Do not point bright lights at people's eyes or onto the field.

Setup

• lights = add(Lights.gobilda("light")); or Lights.blinkin("blinkin") in Robot.java.
• Rules in Controls.java, for example the five lines in lesson 9 section 13.
• Simulator: the light is a dot on the robot.

Steps

1. INIT: the light shows the alliance, not your rules (solid red or blue once it is chosen; LGT-02 tests that part). START: a 1 s flash of the alliance, then your rules.
2. Make each rule true in turn (spin up, aim on, ...) and check the colour.
3. Make two rules true at once: the one written first wins.
4. Fire 3 pieces (fire(3) or hold RB): 3 white flashes.
5. Wait for the last 20 s of TeleOp (or use a short match timer): yellow blinking.
6. Film the blinking with a phone (slow motion): count changes per second.

Pass rule

Every colour matches its rule (all of them), 3 shots give 3 flashes, and the light changes at most 10 times a second (5 on and 5 off).

Record

Write these down while you test. The report form has them as a list to fill in.

• light type (goBILDA RGB, REV Blinkin)
• your rules (copy the lines)
• any colour that was wrong (which rule, what it showed)
• changes per second from the video

If your robot is different

Use your own rules; any true/false works. If a goBILDA colour looks wrong on your light, say which LightColor and what you saw.
