Hey, I was wondering what the other gear ratio for your drive was? I think it's 24 to 60 inside the drive, did you use custom cut polycarb gear to get to 1500rpm for the drive shafts?
I have a question. At 2:53, you push the triball over the barrier, but it is with a concave surface. The concave surface is created by 2 separate things, which could make it concave even if the other wasn't there. The sleds create a pocket that the triball is able to slide into, which is considered concave. The wings also have a wedge on them, which I think is an incredible design idea, except it counts as being concave and not convex or flat. This is confirmed to not be plowing by the addition to the game manual that states that whatever is pushing the triball must be flat or convex. I was confused by this because I am not sure how this didn't end up in a DQ for you if you were holding a triball in the intake while you pushed another one or when you push multiple triballs.
So far we have not really had any issues with referees at any tournaments with reference to the surfaces you mentioned on our bot. One referee did call into question the space between the back sleds as being concave and controlling triballs, but the sleds not protrude enough to turn the tribals with the robot and the back plows the triballs. For that section of the bot the q&a states that it is up to the referee’s discretion. As far as the legality of wedges on the wings, the q&a seems to permit vertically concave surfaces as they function to plow the triballs rather than be in possession of them. “However, generally speaking, we would expect that a "vertically concave" face of the Robot as shown in the sketch would exhibit behavior closer to Plowing (uncontrolled movement in a preferred direction) than Possession.” Hope this answers your question!
I believe currently in local tournaments the judges and refs dont really care about it. However, in higher up level tournaments which are worlds-qualifying or national level tournaments, the judges will be more strict and enforce this rule. This comes from experience where the inspectors were 5x more careful while inspecting our robot during states and signatures. Just be wary of these rules.
I am a bit confused and would appreciate some help here. The game manual defines that cable ties may only be used to secure cables. Am I wrong here or not? The bot would not pass the inspection. My second question is, what do you use on the catapult to shoot the triballs, which component is this black ball? Thanks in advance for the help
Well the first stage is directly attached and tensioned to the endgame and the second stage is pulled up by strings attached to the far side of the base near the hinge. The string acts like a 4 bar and keeps the overhang roughly parallel to its lowered state
Hey Rk, I'm just wondering how you managed to cut your high strength gears in half. I noticed you mentioned them last season on your spin up robot, and you appeared to have them on your new drive. Any help would be much appreciated.
I think your referring to a slip gear? a gear with teeth cut off so when the cata gets so far down there's no longer teeth to engage and so the bands can pull the cata up without interacting with the motor.
Great robot!! Just wondering, are you guys running your 600RPM drive at 100 percent speed? I have my drivebase at 600RPM and it seems a lot faster and uncontrollable than what I saw in your videos.
We start by scuffing the metal so the paint adheres to the surface better, and then put a layer of primer on the metal. After that we just use normal spray paint and apply two to three coats.
They don’t overheat unless a lot of defense is being played or if we are driving for 5 minutes. We keep freeze spray on hand for back to back matches. We have had hot swaps fall off the drive before and didn’t think they were necessary.
If you used 66 watts on the drivetrain and 11 watts on the intake, did you only use 11 watts on the catapult? According to my team's testings, 11 watts is not nearly enough to pull down that much strength. According to the fall reveal video of this robot, it said "25 RPM catapult" so there has to be a motor.
I'm not on there team but I assume that they use a single 100 RPM motor to run the slip gears on the catapult. On our robot with we run a similar linkage and it works great.
I'd assume it's a combination of a lot of things. First, the robot is clearly very solidly built and well maintained. So there isn't much variation mechanically. Then, I would imagine they use a PID that they've spent plenty of time tuning to make it as perfect as possible. Finally, if you've ever been to a comp Robokauz was at, you'll notice that they are constantly working to tune their autons to fields and improve them at each tournament. So really it's the culmination of all the hard work they've put into building, programming, maintaining, and tuning the robot and the autons every competition.
@@polar5717 that is correct. Also there are distance sensors located on the rear sleds which line up with the field to add a field centric element to the autons.
@@robokauzI sort of disagree with this idea as it makes your autos slower, harder to make, slower to make and maintain as well as change and it creates an aspect of limitation around moving around field walls and such to minimize inaccuracy. At least one odom wheel makes it insanely easy and fast to make autos.
@@jadynhasstupid2275 true we have used Odom wheels for years and last year with boomerang control we were able to go fast with accuracy. This year we aren’t using the boomerang or tracking wheels, and we haven’t had any issues since the field movements are not very complicated this year and the Odom isn’t very necessary for us.
