SIM-06: The simulator runs code with MEASURE numbers (stand-ins in the robot file)

medium prioritySimulator only (no robot needed)about 15 minSimulator

• Your robot needs: any robot.
• Starter bots that fit: goBILDA starter bot, REV DUO starter bot, AndyMark Robits starter bot, Studica starter bot.
• Library version: v0.18.3 or newer.
• The docs it tests: The simulator: a pretend Control Hub and Driver Hub, Tunables.java: every number, part by part.

Why

A number written as MEASURE in Tunables.java stops INIT on the robot until it is measured. In the simulator, :sim:fromRobot writes a stand-in for it in the robot file, so the code runs before the robot is built. We need to know that the simulator uses the stand-in and says so, that the real number wins once it is written, and that the robot file stays right after each :sim:fromRobot.

Setup

• Your robot project with the simulator running your code (./gradlew :sim:run), written in five files.

Steps

1. Pick one number in your Tunables.java (for example a servo position). Write down its value, then change it to MEASURE.
2. Run ./gradlew :sim:fromRobot. Open simulator/robot.properties: find the tunable.Section.field = ... line for it.
3. Start the simulator, choose your TeleOp, INIT. Read the note under the Driver Hub ("... = MEASURE: the simulator uses the stand-in ..."). START: the part goes to the stand-in.
4. Run one of your tests (./gradlew :sim:scenario): the init line shows the same note, and the test runs past INIT.
5. Put your number back in Tunables.java and run ./gradlew :sim:fromRobot again: the tunable. line is gone.

Pass rule

3 runs out of 3: INIT goes on with the note, the part goes to the stand-in, and the line is gone after the number is written.

Record

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

• the section and field, the stand-in value written, and whether it was a sensible value for your part
• the note text you saw, and whether it was clear
• anything the stand-in made the robot do that looked wrong

If your robot is different

Any robot with a Tunables.java works. No MEASURE lines? Step 1 makes one.
