how do you plan on making this fit the starting configuration? Other than that, it is amazing!

[@KevinBeshears]

Going to make some sort of pivoting intake. Original idea was a 4bar extension but we are currently working on a new design that we will talk about soon.

[@arrowsmscience9758]

@@KevinBeshears thank you!!

[@GreyLightning]

Has anyone used the idea of a wheel running on the back of the note to tilt it vertically

[@jackofclubs8791]

It’s been like three days, how do you have an intake already

[@nutmeggaming11261]

Ri3D builds a whole robot in three days. It stands for Robot in 3 Days

[@nutmeggaming11261]

This is day two, so tomorrow they need to have a fully functional robot. It won't be the best, but the challenge for building is the goal, plus sharing ideas and designs. Also, usually this is done by college students and alumni, not FRC teams

[@krishivdhupar1639]

is there an example CAD for this you guys post?

[@unusualarrow6390]

do you have a link to the belting used

[@aaronlang617]

What is the size of the two gears you used in order to keep it driven to one motor?

[@KevinBeshears]

They were 32T gears.

[@justindai9631]

Do you guys have the CAD for this otb design? Thanks

[@KevinBeshears]

The CAD is posted to the Chief Delphi thread. FUN's Cranberry Alarm thread.

[@tommypaloooza2985]

arent you not allowed to extend more than 1 foot outside of your frame perimeter? or is this inside the 1 foot margin. technically you can only extend 8 and a half or so inches outside of your frame perimeter considering the bumber takes up like 3-4 of those inches

[@FUNRoboticsNetwork]

You are correct. G413 B states "it may not extend more than 1 ft. (~40 cm) from its FRAME PERIMETER."

[@gavinmorris5448]

How are they connecting the urethane belting to the hex shaft?

[@KevinBeshears]

The belt was held on by friction and tension.

[@luisserranolaguna1610]

how much compress did you guys use

[@KevinBeshears]

1/2'' compression at the start of the intake and 1/4'' compression on the belts.

[@grantspadafore]

What's the angle of the belts?

[@KevinBeshears]

56 degrees

[@matsushitathefifth2862]

Worst new rule ever

[@andyalshabi5189]

What is the rule?

[@TheCubeFactor]

What

[@ThatGuy20091]

There cannot be holes or gaps in the bumper now, therefore the intake has to be outside the chassis of the robot

[@andyalshabi5189]

@@ThatGuy20091 oh, is it only this season?
