The ri3d does not own one but we built this robot in the Purdue Bechtel innovation design center which has a lot of stuff including multiple different kinds of CNCs, laser cutters, and a 5-axis water jet. The hooks are 1/8 steel cut on a laser cutter in Bechtel. - Joey

Thank you, if u look at our other videos u can see the ground intake and shooter are already on this robot. I also highly recommend you to watch our robot reveal video and robot demos to see the full robot in action. - Joey

Thank you so much!!! - Joey

These hooks work the best from what we have tested and are quick drop-in replacements for AndyMark climber-in-a-box hook kits. Some changes that I will be fixing in the CAD soon is to add a centering mechanism on the hooks to try to center the robot on the chain. - Joey

The orange thing is a belt that allows one motor to drive two smaller rollers, which control the note while it is inside the shooter and pushes it forward into the flywheels when shooting. If you would like more info about our mechanism as well as to see it in action, check out our "Shooter Mechanism Upgrade" video. - Daniel

We do not have a full robot CAD but we will be posting the super sketch along with the CAD for the laser cut parts on our Chief Delphi thread over the next few days. - Joey

Ri3D or (Robot in 3 days) is a challenge that some groups of mostly colleges and/or mentors build the First FRC challenge in 3 days. This challenge is for high school students to compete but they have 1.5 months to prototype, design, and assemble the robot. This year the challenge is called Crescendo where the team has to score the foam orange rings into a goal that is over 6 feet in the air and at the end of the game they can earn more points by climbing the chain. You can learn more by looking up "frc crescendo" and watching the game video. - Joey

a rolled up hot dog

A foam ring that feels kinda of like a stress ball. We have to intake it and shoot it into a goal that is over 6 feet in the air for the FRC 2024 challenge called crescendo. - Joey

The amp station is the squarish cutout lower scoring station on the side of the field that can be seen and described better on the FRC 2024 Game reveal video at 1:32. - Joey

It is climbing to score points in the FRC 2024 challenge called crescendo. - Joey

We do not have CAD files of the full bot but we do have a super sketch that we based everything on and CAD of the parts that were laser cut. We will be posting Cad and more write-ups over the next few days mostly on Chief Delphi. We have just been very busy for the 3 days and now we are starting to recap it all. If you have any more questions u can ask them here, Chief Delphi and the FRC Unofficial discord. - Joey

Cad is an abbreviation for computer aided design and is the way that engineers produce accurate digital designs in environments such as solidworks or fusion360

Thank you, your bot looks amazing as well. We used brushed motors for that reason and we had a lot of them donated from teams all over the midwest. - Joey

There is some but not to much lol. - Joey

it's a robot built in 72 hours for the 2024 first robotics competition, whose game rules came out about 3 days ago, they slapped this stuff together in that amount of time. Usually teams have 1.5 months to build something like this, they did it in 3 days

Off the top of my head, I believe it is 1/4 in polycarbonate panels. Either way, it still will be way stiffer than cardboard but we had to use what we had on hand. If we saw it bounced too much while testing different intakes we knew it would not work. - Joey

Thank you for the feedback, we as a first-year and student-run organization built this robot in less than 3 days and in that time we had to prototype, design, and build the robot with the parts we had on hand. We also had to make a lot of the steel and aluminum parts with hand tools due to a lack of good power tools like a drill press that is less accurate than a hand drill and only had 2 drills that do not like to drill. We are trying to get more funding for next year to be able to buy more quality tools. - Joey

it has 6 wheels, it looks like theyre just testing the climb rn

It can drive but we did not want to drive it for the climb test because one of the controllers had very bad stick drift and the deadband was not coded yet. The drivetrain would just always slowly drive to the left, so just unplugged the control for safety. - Joey

bruh pneumatics would require a whole entire pneumatic system with a compressor and air tank for storage because teams need to climb in the last 15 seconds of the match

Negative. You apparently dont know much about them. All you need is a small compressor, two cylinders and lines connecting to a control. A tank isn't neccessary for what would be needed to to do what their doing. People like these kids are always over complicating things with a lot of neccessary stuff. You honestly think this debacle they constructed is simpler than a pneumatic system?? Wow...

@@northernfabricationllc2281 I admit I haven't worked with them, but you apparently don't know much about the meta This is two telescoping arms on a winch, it's fairly simple and standard in FRC, you see it everywhere. What you see here I've seen a hundred times, but I've never seen a pneumatic climb. I wonder why. Besides, the arms weren't painstakingly designed by them, it's a ready-made kit that anyone can get online. Is the actual thing more complicated than pneumatics? Yeah, but the complications of designing it wasn't on their shoulders. It would be much easier to obtain a pre-machined kit that has been tried and true for this exact purpose rather than designing a pneumatic system themselves

@@northernfabricationllc2281You clearly have no idea what you’re talking about. This is a robot for the FIRST robotics competition. If you knew anything about FRC you would know that pneumatics are more trouble than they’re worth, especially when the same thing can be accomplished with motors and telescoping arms like shown here. Pneumatics are WAY more complicated to set up and work with, especially with FRC’s requirements for pneumatic systems.

​@@northernfabricationllc2281Except, your robot will not be allowed to compete due to no Air storage tanks

We thought about it but after making a super sketch with what we had on hand we could not think of a way to get to the trap. - Joey

The telescoping climber tubes are actuated out by constant force springs on each stage, pulling each tube out, and a cord attached to the final stage gets pulled in by a pulley on the toughbox gearbox mentioned in the video. Examples of a COTS version include TTB-TUBE-BASE from The Thrifty Bot (seen in the video), or am-4668 from AndyMark.

@@tornop1thanks!

can you share also an examination link please? I would like to see its inside and how it works @@tornop1

You can find the Cad of very similar climbers called "Climber in a Box" on AndyMark's website. - Joey

@@PurdueRobotIn3Days Thanks, but we could not see where should we connect the ropes. We really have a big problem to simulate it.

Thank you. We are an Ri3D (Robot in 3 Days) team, which means we have to complete our robot in 3 days after the event is announced in order to provide documentation and experience to all other FRC teams. We hope you and your team find our resources and videos useful. -Daniel

We do not shoot to the speaker using our intake, rather the intake hands off the note to a separate shooter mechanism, then folds out of the way for shooting. You can see a rough demo of this process at around 0:50 in our day 2 recap video. -Daniel

@@PurdueRobotIn3Days is it possible if you guys could make a short about trying to do it? It is really interesting but right now we havent started prototyping

Thanks for the pointer, we did notice that the hooks slide down the chain. It was not covered in the video, but if we have time left, we are planning to laser cut spikes/serrations and attach them to the hooks. -Joey

In our current pickup configuration, the center of the 2" front roller is 2.75" off the ground. We'll post a full CAD by Wednesday including our super sketches that we used for the all the core mechanism geometry. -Michael

Yes we are considering the angled top of the amp station! We didn't build it into our field element yet but will have it there for day 3 when we are doing more testing! A big part of the reason we are pursuing more of a pick and place amp scoring mechanism rather than a shooter is because of the angled top! - Michael
