When the robot senses the mobile goal it automatically lifts it while slowly driving forward such that the stack stays on place.

Prototype V_0.0001: Did not generate enough lift. Back to the drawing board... Please, leave any constructive suggestions in the comments. We need to get this thing flying by January...
This is really nice, the only real problem I can identify is the possible difficulty that can be found on trying to fit in two stacks, which can be fixed relatively easily
I actually think v2 was better ngl
I believe these are not VRC legal as it involves modifying a motor which is not allowed.
I believe you are stupid
I have no idea what you said, but there's seems to be a lot of effort put into this video so I'll drop a like.
I had always figured that since you aren't allowed to modify any motor parts per the rules you can't use the internal gears from the motors anywhere else on the robot but I guess the rules do only say you can't modify them for motor usage so props to you for finding an innovative way to use the gearing.
Amazing animation.
Are people allowed to use part of the designs?
Obviously. This is VEX we’re talking about 😂
Hey, quick question: I assume you're using Blender for animating. How do you do it? Do you CAD in another software and then import the whole assembly to Blender with Blender maintaining all the part relations and constraints from before? Or do you have to make it in Blender?
That’s illegal?
1:21 youtube compression go brrrr
Quick question: Where do you get the models for this?
lol they make it themselves in cad
Great idea How could you do that?
What software do you use for the video?
G5 you can't have detachable parts and I'm pretty sure a ref would call thecage as one. Even if it is attached but a string.
Nope, as we can see in spin up detachment is not allowed in the last ten seconds, but string shooters are.
how did you do the animation??
What animation software did you use? The quality is stunning.
That's a nice rope you've got there, it would be a shame if it caused an entanglement
xD
it's illegal, they'd get disqualified.
G16 you can’t use the design
This is a great idea! I don't think it would violate any rules either. G16 states that your robot cannot intentionally grasp onto any field elements, and it obviously can't damage the field. Correct me if I'm wrong, but if you built the clamp big enough, it would technically clamp AROUND the field element, not ON the field element. As far as damaging the field, you can take measures to prevent that, like turning the threaded end of the screws to the inside, so they don't puncture the field.
And if the other team moved it, then it wouldn’t be intentional 👀
1:21 You are welcome.
Imma remind ya that something called G16 exists
Chastity belt
How would you bend the ninety degree L channels the extra 45 degrees?
Sweet! Wonder if the spider thread will get difficult in real play. What did you use to make this video? Reading other comments, it sounds like blender.org. Maybe for lockdown you could do some video making tutorials for beginner teams :)
Yeah they animate everything in blender. I'm sort of curious about the string too. I saw a few reveals last year which had tether bots, but I haven't really seen one in an actual match. People seem to think nothing will get tangled, but I'm still skeptical.
Can you stop making the rest of us look bad with your insane animation skills. Thanks
Awsome bot. What is this rendered in
They do all their animations in blender
Could the cage be deemed as clamping onto the field?
It is difficult to determine as the rule defines clamping as grasping on multiple surfaces to prohibit movement and this type of cage only grasps one so the rulings could be very discretionary.
The issue you will have with the cage though is the fact that the rope used to keep it attached to your robot could be deemed as an intentional entangling device
@A Person The problem with the forcing someone into the penalty is that they are intentionally laying the cage down and the string along with it in order to play defense. The refs would classify the string as part of the defense and therefore the robot is now a defensive robot. The other team that drives over it and gets entangled in turn would must likely be an offensive robot and because of vex rules offensive robots get the benefit of the doubt. The refs wouldn’t call it in favor of the defense on this because the rule states that they can’t.
I'll give you this - it's the most interesting concept I've seen so far. I could only wish to be that good with blender. It's a cool design but I still think I'm going to build an offensive wallbot. Spider bot, Spider Bot, does whatever a Spider Bot does!
would it really be that hard for a snailbot to run-up while the spider bot is turning around and mess up the ball stack?
nice transmission but I'm p sure double rachets have lower frictional losses if built right this just seems to have too many downsides and the anti-chamber LMD differential would have been much better suited for this application Edit: that's not to say I don't think this is cool I think this is very cool just noting practicality seems low
I hope designs are more varied this year. Tower Takeover was awesome, but most robots had the same basic design. This looks epic though, so I’m hoping this is up in the meta this year
So you guys got really good at blender over quarantine. That was really cool
Just know you are not the only one to think of this... There are others if I thought of this 6 days ago. Means the competition going to be stiff ;)
its just a concept design lol
Great animation, but G16
G 16 states that the robot can not clamp into the field, what he has just flipes around and locks onto itself, while just sidding on the ground around the goal... He is not gripping, it is just setting there, on the floor
The full G16 "" Don't clamp your robot to the field. Robots may not initially grasp, grapple or attach to any field elements. Strategies with mechanisms that react agents multiple sides of a feild element in an effort to latch or clamp onto said field element are prohibited. The intent of this rule is to prevent teams from both unintentionally damaging the field and/or from ancoring themselves to the field. So if you built a robot that could make a circle all the way around the center tower with a 12" gap all the way around, would that be laching or grasping onto the field element? If not then the same would go for this mecinism, it is not touching the field element, it is a wall that is resting on the ground, preventing access to the field element. If this mecinism wraped around the center tower, touching it all around, then that would deffently be classified as a violation . It also says that the mechanism has to react with many sides of the object, this would be true only if it is being pushed around, which would be done by an opponent, theyby by G 14 which says you can not force your opponent into a penalty, that would be void. It also is not anchoring for the same reason. Example is like in tower takeover, if someone pushed you into a tower, that does not mean that you are anchoring yourself to the tower... See what I mean?
M W Note G16 encompasses strategies, which an opponent cannot force. Additionally, G14 (the opponent forcing rule) has be interpreted by the Q&A every single game to not apply to an offensive bot aiming to score (why it was not illegal to push a defending bot into the inner protected zone when going to place a stack).
@Kyle Miller when you deploy the cicular wall you are not meeting the defenetion of grasping and locking. The robot piece is directly setting on the floor not touching the goal on multiple sides. Theyby by being pushed around would be an opponet acting on it. There is one tower takeover match where there is a wall bot that traps both opponets in the goal zone. But one robot gets away by folding the arm back on the robot, like that video the wall bot was pushed into the towers, which stopped it from being pushed out, but it was not classified as anchoring. For this macinism to reach with multiple sides to opposing team has to push it in multiple direction untill it hits the goal zone in multiple directions.. I thinkthe rule is more of have a claw that grabs the tower,and grasp it and holds it, not a loop around the tower. Using your logic if you drove up to the tower and have your intakes up so you bassiclyy are around three sides of the tower without touching, that then would be considered grasping and locking. I dont think that is what the rule means... I mean do you see what I am meaning? How can you hold something without accually touching it?
G5 Robots may not intentionally detach parts during the match or leave mechanisms on the field
Pretty awesome as always
You guys never cease me with your animation skills. Good luck this season! -1961Z
Hey! The 2020 game updated. Do you reckon you could build an example robot?
spinning motor, bruh
Love your transmission!
what rpm motors did you use for the drive/tilter? Also, what did you use the 8th motor for? 2 motor lift or something else?
rip vex worlds
What did u use the extra motor for?
that extendable stacking device is actually ingenious.
Is there an available CAD or Solidworks model?
These animations shouldn't be used to design your bot or use the idea. They don't show you the problems and such, it just shows an idea that might work
How to make this video
or you could just use a differential gear
This doesn’t work,which is pretty obvious
Hello. I am a player and coachfrom China. It's really cool about ur video. How to make it? VEX VIRTUAL WORLD or something else?
