i’m sure you guys already know, but watch out for G405, it could really hurt your score and it seems like not too big of an issue to fix. Amazing bot and congrats!
On those same questions, what string did you find works best? And how do you prevent problems with the slides (i.e. string coming off of spool, string breaking, etc.)
@@ishpen282 Our pulleys are the opensource pulleys found on Loony lib and we are using 1mm diameter kevlar for our string. In terms of preventing issues we use a high load ziptie to tension all of the string to make sure there won't be any slack.
Hi, your robot is great and the driving was very good. I've watched the video carefully and a visual measurement using the tiles as measuring sticks seems to suggest that when all extensions are fully extended your robot is longer than the allowed 42 inches. I know that you are a very experienced and successful team and so you wouldn't have made that error. What is the length of your robot with all extensions maxed out?
So our full extension with everything fully out is more then 42 inches we did software limit it to be under 42. The refs were very chill with extension limit since its a scrim we have plans to fix it by our next competition.(We also positioned our robot in the sizing box at a angle to get a bit more room on the extension)
How does your intake on the vertical lift work? It seems to rotate on an axis, but there seems to be no servo doing it. How are the rubber bands helping it rotate and what exactly is allowing it to rotate?
We use a differential system there, so the same servos that rotate the claw up and down also power the turning. We use tubing as elastic to spring our arm so that the servos do not have to work as hard to bring it up.
Hello, I was wondering, why are your slides set at an angle, and what angle did you set these slides to, if possible to share? Are you guys facing issues with balancing weight on the robot with tilted slides, and if so, how did you combat this issue? I would love to implement some of these things to my rookie robot!
Hey! Our slides are 75 degrees from the horizontal, which we did for hang. We haven't had any tipping issues so far. If we ever do start to tip, we can extend our intake slides to balance it out, so it's not much of a problem for us. Good luck on your robot!
How does your intake support for claw roates? I see your rotation of claws and the rotation of the intake arm working,but how are you moving your support(i dont see a coaxial servo for it)
We are using a differential Gearbox to control the rotation of the claw. FTC team 8644 has a behind the bot from powerplay which demonstrates how it works really well.
We buy our slides from MISUMI. They are more compact, lighter, and glide smoother than viper slides. The downside is that they are more expensive, however we believe this is a worthwhile tradeoff for a more reliable and efficient linear sliding experience.
Awesome robot! Go Aperture!

Thanks for bringing this up we forgor 😭

Did you guys use belts and pulleys to extend the vertical and horizontal slide?
Horizontal slides are a linkage powered by two servos, vertical slides are string and pulleys.
Where did y’all get your misumi slide pulleys and pulley attachment design from? They look really smooth

For the deposit slides we used the open sourced one on LoonyLib.
@@ishpen282 V bearings help a lot with string not coming off.
Why are the linear slides at a angle? Ive seen this on a few other bots as well
For hang!
what pathing software are you guys running for auto?
We use a custom pathing setup with a position and angle PID controller

What screws do you use to attach the actual Misumis to your 3d printed parts? Are they threaded in or some low profile nuts in there?
Sorry for the late reply; MISUMI slides have threaded holes
What Linear sliders are you using? We have trouble finding sliders that are compact
We use MISUMI SAR240's for lift and SAR330's for intake!
@@5064ApertureScienceour slide uses insert to connect different slides together. Do yours just extend in one go or did you guys do the same?
Technically, how are these slides that speed and can rung the level 2?
They definitely aren't as fast as they could be. We chose torque for hang over speed for scoring!

We are using a differential Gearbox to control the rotation of the claw. FTC team 8644 has a behind the bot from powerplay which demonstrates how it works really well.
what rpm motors and spool diameter are you running?
435 RPM and goBILDA's 42.5mm spools
How does the differential in your claw work? Like are the servos moving the arm up and down also the same ones rotating your claw?
No, we have 2 servos moving the arm up and down and 2 servos operating the diffy for the claw to rotate and flip over for transfer.
Do you have a detection camera in your claw for auto?
Yes we have a camera on our intake arm that tells the robot where the specimen is.
@@benhicks3011 Does it also determine what the orientation is?
@@JohnPlazy Yes it determines orientation and location
What kind of camera? Is it a Pixy2 if it’s doing detection???
It's a Global Shutter Camera!

Are you guys localizing during auto using april tags or just standard odometry?
We're not using april tags yet. Currently we have one SparkFun OTOS which handles localization very well.
What is this???!? Is it vex?

What are the slides? I see teams use them, they seem so much more compact then gobuildas.
