Hi All!
Our team has used a mogo mech design from the Tipping Point, but I think it does not work for High Stakes because the stakes are a bit different.
Can anyone give us some examples on mogo mech that their team has?
Our team surely will not go to Worlds (Only Koreans will meet us in Nationals), so please give us your ideas.
Thank you!
You can find these on YouTube. The main mechs are Redirects, Fish Mechs, and by far the most popular, Lady Brown Mechs.
are you referring to wall stake scoring or a goal clamp?
Oh that’s my bad I thought they were talking about wall stakes for some reason. For mogo mechs you can just go to YouTube and look up High Stakes Mogo Mech. There are tons of options.
@Zach_41819 if you are looking to improve your wall stake mechanisms, the basis of most mogo mechanisms are as follows:
a. They are usually powered by 1-2 pistons connected by the same solenoid so they are not controlled individually.
b. There is usually some sort of a bar (whether that be a high-strength axel, L-channel (though I would not suggest them as they are quite easy to bend or snap), or a c-channel) that spans from one end of the drivetrain to the other end while also being very low to the ground (borderline scraping). This is where the mobile goal will sit to prevent it from dragging along the ground. When driving backwards in to the mobile goal, the front of the goal is lifted and put in the optimal position for the clamp to grab it.
c. A clamp that usually consists of a c-channel, standoffs, and/or bumpers that aim to push the front of the mobile goal down after the front of the mobile goal has been lifted off the ground by the bar previously mentioned. I’d suggest a clamp consisting of a c-channel which sits parallel to the ground when the pistons are pulled back, with either standoffs or bumpers coming off the end that will pick up the mobile goal (be sure to leave space for the mobile goal to get between the clamp and the bar), and then become angled downwards to push the front of the mobile goal down.
Obviously you will have to do some testing and some tuning but I wish you the best of luck! Also, try not to tell yourself that you will surely not go to Worlds, with good enough driving and some solid auton, even some build-lacking teams can make it to the top! Good luck.
some examples of mogo mechs (Might not fit all the criteria I previously mentioned but they have good aspects):
Can we have a direct motor clamp?
My team used a direct 100 rpm motor mech for our first 4 competitions, and it worked really well. It didn’t overheat quickly and it held the mogo firmly. If you can build one correctly, it can be just as good as a pneumatic clamp. I unfortunately do not have an image as it has been disassembled.
How did you program it?
I don’t know, as I’m not the programmer on my team, but @Imadumdum might be able to answer.
In C++ you would create a new device pneumatic, and basically program it like a boolean, so when the button is pressed, “engaged” is true, and the piston extends until the button is pressed again, which flips the switch.
for pros 4.0.0
void initialize() {
pros::Motor clamp(1)
}
void opcontrol() {
while(true) {
if (master.get_digital_new_press(E_CONTROLLER_DIGITAL_L2)) { clamp.move(127); }
if (master.get_digital_new_press(E_CONTROLLER_DIGITAL_L1)) { clamp.move(-127); }
}
}
I meant with motors (b/c pneumatics don’t overheat and only have two positions)
hmmm maybe I should do spin to position or something like that (and hope it doesn’t overheat)
you could have it just spin relative to a button you press, either up or down, then have it hold when no button is pressed.
