An RI3D I built in late July to scrim with the Kansas Teams attending MOA. Overall I would highly recommend this design to newer teams in vex. If you have any questions, feel free to ask. Good luck in Over Under.

hmmmmm cool, imma have to use this as some inspiration since i still don't know how to build something that isn't terrible ☠️ i do got a 6 motor 257rpm chassis tho (with some stacked motors), glad to see that's not a dumb drivetrain idea

Can you provide link for the omni wheels, explain further what type of wheels are they either bush type or bearing.

@9MotorGang 10 ай бұрын

They’re just the standard 4.125 inch Omni wheels on vex’s website.

would it be legal to have something grabbing on to the corner barrier to ensure a shield against defending bots?

@Spidooooo 11 ай бұрын

no, that would be in violation of rule G7

Would love a build tutorial!

Unfortunately, the robot has since been disassembled. If you have any questions, let me know.

Why do you have three red gears if you only have one shaved gear. What do they other two gears do?

@9MotorGang 9 ай бұрын

The 48t gears act as a glorified lock bar. They ensure the cata arms spin with the shaft.

Whats the plan for when the code get turned off at the end of the game, is there a locking mech for the hang

@9MotorGang 7 ай бұрын

There is a ratchet on the bot. At 4:05 you can see the program is off and the robot is still hanging.

also what is the gear ratio and how much is shaved off

Those standoffs are looser than the ones that hold up middle schoolers license plates

Rubber linked, not loose.

@9MotorGang 10 ай бұрын

I'm not sure what you mean. The robot doesn't have a high hang, and the catapult is explained in the video.

Do you use 200 rpm cartridges for your drivetrain?

@9MotorGang 7 ай бұрын

No. 600rpm.

@yeetingdon1880 7 ай бұрын

@@9MotorGang my school doesn’t really possess 600 rpm cartridges, nor even any form of pneumatics. would a 4 motor drive with a speed ratio of 60:36 be best for our drive train?

@jonnyedit 9 ай бұрын

why do the cata thingys wiggle wiggle

@9MotorGang 9 ай бұрын

The code is just set up to spin the cata if it is less that a value. Then the motor stops and due to slop the robot drops beneath the threshold. So the motor re engages and then the cycle repeats.

@9MotorGang 9 ай бұрын

@@jonnyedit The standoffs are mounted on rubber links so that it can drive under the barrier
