Hey everyone, I’m working to program a catapult and have some questions. The catapult is powered by one motor, and is built on a slip gear. There is a limit switch placed so it is triggered right before the slip gear releases the catapult; so it is basically extended fully back. Basically like ever…

Just as an update, I came up with this based on some logic and I think it makes sense. Lmk if not if (!limitswitch.pressing()){ cataspin(); } else { if (Controller1.ButtonL1.pressing()){ cataspin(); } else { Catapult.stop(brakeType::ho…

Sounds like a similar setup to what many users used in the IQ game last year. Review this post that includes a vexcode file on one way of coding a catapult. [image] Herobot: Fling Unofficial Thread VIQC Pitching In (2021-2022 Game) I’m sure Mr. Pearman is right about VE…

Can you post what code you currently have?

Yeah void cataback() { if (Controller1.ButtonL1.pressing()){ if (limitswitch.pressing()){ Catapult.stop(brakeType::coast); } else { Catapult.spin(vex::directionType::rev, 200, vex::velocityUnits::pct); } } } edit: by mods, you need three backticks to format code, not on…

In pseudo code you want to Press button - spin Spin until a sensor is actuated Stop It is now “loaded” So if you press the button again, the stop sensor is already pressed, so you have to ignore it for X seconds (enough to get off the sensor but before it gets back around to press the sensor a…

When you talk about the wait/timer, would that basically mean the motor is moving forward, then backward again? Not quite sure what you mean, specifically with the limit switch

You have a pretty good start. What I do is when my button is pressed, I spin the motor for a fraction of a second–just enough for the slip gear to disengage–then I run the conditional.

You may want to make your button the first option so it takes precedence over all other modes. The limit switch could interfere if you were trying to manually fix an issue. A reverse option might be helpful too.

if (!limitswitch.pressing()){ //<-- First priority cataspin(); } The limit switch is the first priority and will ignore the driver’s buttons if the switch is not pressed. This means if the catapult jams during a cycle, the driver can’t fix the issue. The limit switch is not press…

update to this; my logic worked, this code is perfect for anyone looking to run a loop
