Hey I really apologize for this, but I'm pretty sure since your floating intake tecnally moves foward and expands fowards that your backwards expansion with both that and your mobile goal holder isn't possible. I could be wrong, but tecnially if it goes fwords at all which I believe it does from the look, it can't be done
Heyo, thanks for expressing concern but we believe that it is still legal as they expand in the same direction and does not breach the 3rd plane. when the mogo mech is extended it does expand in the same direction and the 4 bar does as well but since they are the same direction and in the size limit it is legal. Thanks for watching ❤
So if you feed it a ring whilst the entire mechanism is raised, can it still score or do you have to lower the mechanism every time you intake rings like other bots?
Yes, the robot can store 2 rings in the top of the intake but will have to go down to get 2 more. We are feeding donuts directly into the 2nd stage for demonstration purposes.
@@Febreeze4139B I see thank you, could you potentially use the gap between to maybe have some sort of flex wheel system that transports rings into the 2nd stage? It's a stretch but with some time you might be able to get it working.
Im honestly not sure but there is a low chance of having enough clearance, but i will see as we are redoing the mogo mech since this revision is kinda mid. Will get back to you when its tested :)
Its a normal 4 bar which uses 2 pistons to power it. Its then banded using rubber bands at points that are closer together when extended than when retracted. The first stage is just flex wheel connected by chain with 2 blue motors, the second stage runs off the first stage using chain with 1 set of gears to reverse the direction, the chain is then run up to the top axle to power the chain lift with the hooks. This means that the entire system has the torque of 2 motors (assuming no losses, so more like 1.5 motors) while running at 600rpm. Hope this helps :)
Its a idler bearing on the sprocket so that the chain stays in tension when the intake is lifted up. though in the video it was implemented wrong, you want it so that it is the same distance from the pivot at all times ideally
This is a wild idea we had but on the second upper part of the lift have you considered somehow positioning a piston such that it can tilt that tray so you can score in both directions. Idk if you get that but it would essentially just be a piston that when retracted the tray outtakes in one direction then extends to pivot the tray and outtake in the other direction
The mogo can go in from every angle and it works the same in our testing, the wedge design is proven in tipping point, and we can use a regulator (which will use about 5psi per grab) to minimise the air usage. Only two of the pistons need to be powered because the exterior pistons are there for positioning. The vex pistons are also very hard to bend unlike the older smc ones, and the claw that grips onto the bottom of the mobile goal lets go far before the pistons even get stresses significantly, and since this mechanism can be depolyed/undepolyed most of the time the pistons will be retracted anyway, as the pistons are set to retract as default. A v2 slider version is in the works though.
The smcs are easy to bend but the vex ones are m4 so its pretty hard, either way we can use a slider The claw that grabs also slips far before the pistons will bend so the mobile goal might just drop, but we will see in matches
I mean a rule of thumb for pistons is to place them in the most safe position. The pistons themselves are very expensive so even if they are more durable than the smcs I wouldn't place them in this position because of the contact of other robots. However you could do something similar to this design. Instead of the two pistons on the outside you could place them on the inside and have them move a platform up and down. I could make a quick sketch of this idea and send it to you through discord if you would like.
@@Isaacc11618 Yeah agreed, i will definitely change it to move pistons out of the way, if you could provide a sketch of your idea that would be great, thanks :)
yes it does work the other orientation as well it just likes this one better ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2v7I9usSc_A.html (Orientation showcase) (v2 slider ver with 2 pistons in le works, open to all suggestions :) )
Wait, if the intake is 15 holes wide then the internal width would be 13 holes. If 1 hole is 0.5 inches then 13 holes is 6.5 inches, but the ring itself is 7 inches so how does it fit?
