Nice robot! Are you guys planning on climbing and hanging? My team has finished our climbing and hanging part and is now adding some block and ball manipulating parts!
Awesome robot just a couple of quick questions. Hoe hard was it to stabilize that arm? Looks pretty far out, also did u just deem climbing up the ramp to take to long or to difficult to do? Our team is still in limbo over what way we need to focus just seeing what other teams thought processes were thanks!
+Allan Huntington climbing takes too much time. We can collect and score 4 or 5 loads of blocks in a match and also get the zip liners and do autonomous. That puts up a higher score than any of the climbers however a climber would make a good partner for us.
+Triston adams The arms? I guess you mean lift is the Textrix rack and pinion. The slide for scoring blocks is the camera slide by Actobotics that we saw on the ServiCity web site.
+MasqueradeFTC but are those belts or pulleys or something attached to them? I'm assuming you guys only are using the motors at the base of the lift, but I'm still uncertain how exactly you made it work. Thanks for the response
+Triston adams The lift is Tetrix rack and pinion for the first tier and the rest move with the cascading string. The black parts are 3D printed and they hold the bearings that the string glides through. You may want to look at the ERX (Eagle Robotics 5257) UA-cam site. They did a robot in a weekend at the beginning of the season and they go over how they built their lift. That is what we are using.
+Jordan Snodgrass One match we did have a problem where one of our motor controllers lock up. What is interesting is with the new system only the one box goes out and not the whole system. Because of this we were unable to move the lift but we could still collect blocks and score in the low basket. Disconnecting specifically was not a problem at the event but we have had problems during practice where we just have to restart the phones to fix it.
How fast are your 3 sweepers on the front spinning? Or what gear ratio or RPM do you have? Just wondered how fast they have to spin to pull in the cubes. Can it pull in balls too?
+icecats It's amazing this is the first time that this question has been asked. Our lift is actually power up and power down. Naturally rack and pinion is power up and power down but that only gets the first tier. We took the same cascade string system that we have made in the past but duplicated it so that it would cascade down. After messing around with the large amount of string we established it could actually be one long string that forms the shape of a circle. I promise it makes more sense once you play with cascading power down lifts.
+Yafet Beyene Awesome question. We have 2 different buckets that we swap out before each match depending on which alliance we are. Apparently the only footage we used is of the red alliance. Because our horizontal slide is a 360 servo it doesnt know the difference as to which box is in the robot, it either goes left or right and that is all on the driver to know which way to move the slide.
we ordered timing belts that turned out to be useless and so we used them for extra traction on wheels but we're currently looking for a better timing belt kit. do yall have suggestions on what to use?
+MasqueradeFTC thanks! also one more question about the arm. we have the arm from our first version robot that looks just like that except the channels were not cut. I was wondering what effects and for what reason did tall cut it? we don't want to cut channels without knowing there's a benefit. that's why we kept them whole to began with lol
+Antonalog good question. We are using the Tetrix rack and pinion on tier 1 and the other tiers are just the rack parts with lithium grease. They are attached to Tetrix long c-channels that we have cut in half.
+MasqueradeFTC I just wanted to know what all things your robot accomplished in the Autonomous mode. I am lead programmer for team 4444 (Whitefield Robocats) and I just wanted to get some info on what other teams were doing for Autonomous mode. Thanks, Simon
+Simon Alexander Right now we just score the climbers in the box and get out of way so partner can do the same. We plan to add the color detection later. Hope we all get to Worlds and we can win together again like 2012. Good luck.
+MasqueradeFTC I wish you guys luck and cant wait to see your robot in action soon. One more Question though... Are you guys using encoder with your robot. If you are where is a good resource to learn to code them. THanks, Simon
+Daniel Shorr Just for affect. You are the first that said they noticed. I thought it was silly also but then I did not edit the video but I like the music.
+Scott Parsons The first tier is rack and pinion and tiers 2 to 5 are moved with string. It is a cascading lift. All the string runs through V-bearings that are housed in a 3D printed part we designed. Each tier is connected with a special bearing lift we design. For more detail you can look at the comments on our robot reveal video.
+MasqueradeFTC So does it use gravity/weight to come back into the bot? because my team used a cascading lift using slide lifts last year and the only way to get them back in was to use gravity.
+WingusDingusRobotics We are running the Moto G phone on the bot because the battery runs longer. The Moto G is running Lollypop. The driver station is the ZTE running 4.4.4
Brilliant guys! Congrats!
+Noelle Anderson Thanks
When you score in the mountain goals are you all the way on the ramp? Very impressive!!!
+dodger 815 Yes we are above the white line. You can see it more clear on our reveal video.
Loved it, nice work.
+RawSauce338 Thanks
How amazing it is to see what is possible. Thanks for posting!
You deserve every win you get. Admirable how hard you worked on this.
+Rein Teder Thanks
Thanks for using Colbreaks... Amazing robot guys!
WTG Masquerade. I look forward to seeing this bot in San Antonio. Be prepared for lots of teams to mimic your design.
+Mannie Lowe We know but that is okay. Lots of teams have been having issues so we wanted to show a good solid design. Good luck to everyone.
You guys did it better than i2r
Nice robot! Are you guys planning on climbing and hanging? My team has finished our climbing and hanging part and is now adding some block and ball manipulating parts!
+Nathan Satterfield We are working on that right now.
Cool you should check out my teams (3507 Robotheosis) robot. Videos are on my channel.
Nice robot! Might I ask what you used for the sweeper mechanism?
+Gamer232423 “Nicholas” ` surgical tubing on PVC. There are three tiers of it to get the height needed.
Awesome robot just a couple of quick questions. Hoe hard was it to stabilize that arm? Looks pretty far out, also did u just deem climbing up the ramp to take to long or to difficult to do? Our team is still in limbo over what way we need to focus just seeing what other teams thought processes were thanks!

do you think you could give a more in depth explanation of the arms/belt idea you have going on?
+Triston adams The arms? I guess you mean lift is the Textrix rack and pinion. The slide for scoring blocks is the camera slide by Actobotics that we saw on the ServiCity web site.
+MasqueradeFTC but are those belts or pulleys or something attached to them? I'm assuming you guys only are using the motors at the base of the lift, but I'm still uncertain how exactly you made it work. Thanks for the response

Great job! Do you guys have any problems with disconnecting durring match?
+Jordan Snodgrass One match we did have a problem where one of our motor controllers lock up. What is interesting is with the new system only the one box goes out and not the whole system. Because of this we were unable to move the lift but we could still collect blocks and score in the low basket. Disconnecting specifically was not a problem at the event but we have had problems during practice where we just have to restart the phones to fix it.
How do you guys lower your linear sliders? Do they work purely because of gravity or do you have a mechanism designed to lower the sliders as well?
It is power up and down with string
I must say as a fellow FTC competitor why do I even try when there is that
Awesome design!! Congrats on the High Score, too!!
What pulleys do you use on your slide? They seem interesting.
Are you guys still planning on going for the hang?
+Peter Sauer maybe. We are looking at options now.
AMZING Design :D simply Amazing
How fast are your 3 sweepers on the front spinning? Or what gear ratio or RPM do you have? Just wondered how fast they have to spin to pull in the cubes. Can it pull in balls too?
+Karter Krueger Yes we do balls and blocks. We are using a 3 to 2 gear ratio on the collector. It could be faster so we may speed it up.
Would you guys mind sharing your CAD models? Thanks
So how does the end of the arm work in terms of what side of the ramp you are on? Is the end attached to a servo so it turns or what?
How does your linear slide move back down. Is it gravity powered or powered down by a motor?
+icecats It's amazing this is the first time that this question has been asked. Our lift is actually power up and power down. Naturally rack and pinion is power up and power down but that only gets the first tier. We took the same cascade string system that we have made in the past but duplicated it so that it would cascade down. After messing around with the large amount of string we established it could actually be one long string that forms the shape of a circle. I promise it makes more sense once you play with cascading power down lifts.
what type of material is on the inside of the box? We have trouble with using a sloped ramp to distribute the blocks.
+Kenneth Lin Its a 3D printed wedge coated with teflon sheet. We also have teflon sheet on all sides of the box where the blocks could touch.
thanks for the quick reply
How will you guys score as the blue alliance? It seems as though your bucket is built to score from the left.
+Yafet Beyene Awesome question. We have 2 different buckets that we swap out before each match depending on which alliance we are. Apparently the only footage we used is of the red alliance. Because our horizontal slide is a 360 servo it doesnt know the difference as to which box is in the robot, it either goes left or right and that is all on the driver to know which way to move the slide.
What are the black sweepers attached to your intake system made out of?
+Default Robotics We use .5 inch thick black surgical tubing.
we ordered timing belts that turned out to be useless and so we used them for extra traction on wheels but we're currently looking for a better timing belt kit. do yall have suggestions on what to use?
+Azim Daradiya We use Actobotics timing belts and they work great for us. Got them from ServoCity.com.
+MasqueradeFTC thanks! also one more question about the arm. we have the arm from our first version robot that looks just like that except the channels were not cut. I was wondering what effects and for what reason did tall cut it? we don't want to cut channels without knowing there's a benefit. that's why we kept them whole to began with lol
+Azim Daradiya Which arm do you mean? We cut channel on the lift for space reasons and we cut a corner of frame when getting off mountain.
What is the linear slide made of?
+Antonalog good question. We are using the Tetrix rack and pinion on tier 1 and the other tiers are just the rack parts with lithium grease. They are attached to Tetrix long c-channels that we have cut in half.
Hi,
If you don't mind could you please tell me what kind of gyro you use?
Thanks
adafruit imu
What all does your Autonomous program consist of?
+Simon Alexander I am not sure what you are asking. Can you be more specific about what you would like to know.
+MasqueradeFTC I just wanted to know what all things your robot accomplished in the Autonomous mode. I am lead programmer for team 4444 (Whitefield Robocats) and I just wanted to get some info on what other teams were doing for Autonomous mode.
Thanks,
Simon
+Simon Alexander Right now we just score the climbers in the box and get out of way so partner can do the same. We plan to add the color detection later.
Hope we all get to Worlds and we can win together again like 2012. Good luck.
+MasqueradeFTC I wish you guys luck and cant wait to see your robot in action soon. One more Question though... Are you guys using encoder with your robot. If you are where is a good resource to learn to code them.
THanks,
Simon
+Simon Alexander Yes we are. Send an email to MasqueradeFTC@gmail.com and I will forward to our developer.
What parts did you use for your sweeper?
Can you suggest a point of reference for learning to program the sensors?
I see you are using the actobotics camera slider. Did you cut it down? Because isn't it 24 inches long
Just a quick question do you know if we can use the vex tank treads?
+MRnoobbagger I believe they but if you are not sure then ask in the forum.
What kind of sensors did you guys use for your autonomous?
+Brian Sturdevant Gyro and now color sensors too to follow lines on field. The Gyro can also detect tipping when on mountain.
OK thank you
What kind of wheels do you use to get up on the ramp?
+robinvh99 Standard Actobotics wheels
Did anyone notice that the time of 24s-37s was a video played forward and then reversed. Why was this done? It's very confusing to the viewer.
+Daniel Shorr Just for affect. You are the first that said they noticed. I thought it was silly also but then I did not edit the video but I like the music.
+MasqueradeFTC what's the name of the song?
Colbreaks (I think its 2011)
Is it motorized when you pull it in or are you guys using gravity?
+Scott Parsons Power up and power down
+MasqueradeFTC Ok thanks and one more question how did you make those slides move out and in? By the way I love your robot!
+Scott Parsons The first tier is rack and pinion and tiers 2 to 5 are moved with string. It is a cascading lift. All the string runs through V-bearings that are housed in a 3D printed part we designed. Each tier is connected with a special bearing lift we design. For more detail you can look at the comments on our robot reveal video.
+MasqueradeFTC that are below this one.
+MasqueradeFTC So does it use gravity/weight to come back into the bot? because my team used a cascading lift using slide lifts last year and the only way to get them back in was to use gravity.
What's gear ratio on the drivetrain?
+TheKaziCo ratio is 3 to 2 for power.
MasqueradeFTC I'm assuming you used NeveRest 20 or 40?
+TheKaziCo correction the drive train is a 1 to 1 with 40's.
MasqueradeFTC Thanks
what are the vertical pieces at 0:40 called? where can I get them? or did u guys have to drill all of those holes
+Haon Zoldak The silver parts are Actobotics C-Channel that you get from Servo City.
What kind of wheels are you guys using?
+Dante Strange They are standard Actobotics Wheels. 5 inch I think.
Is there any notable issues with weight distribution?
Dante Strange We keep it as low as possible to the front as climbing. We have to be careful not to tip back until we latch.
What version of Android did you end up using?
+WingusDingusRobotics We are running the Moto G phone on the bot because the battery runs longer. The Moto G is running Lollypop. The driver station is the ZTE running 4.4.4
What is the music name?
+최종은 sandstorm by darude
Johanna Andrick Thank you very much.
+최종은 Deaf Kev - Invincible
***** You are right. thanks.
