The Thrifty Bot
Thank you for your support! - Розваги
I like how there's just two dudes standing behind the goal keeping it up
CEO of ri3d right here. All you teams out there start the hole count.
Fantastic work!! Team 7448 here is glad to see some ideas like this, coming from rookie year last year we are looking up at teams like you guys for inspiration and this gives tons! Thank you!
That lightsaber finale was so epic
Very impressive how fast you designed and constructed the robot! Great work!
That's a big brain bot. We're gonna have to steal the high level shooter idea idk.
By far The best ri3d for this season. You're climbing is awesome!
Definately showing my team this
Nicely done!
Nice job! That's awesome!!
Great job!
Well done!!!
Nice job!! Way to go Gophers!
Nice robot!
Which motors are you using ? I was actually preferring banebots... But There is some problem with base motor and gear box... There are just two bolts between the gear box and motor, and that's not enough to hold them. So, do we need to replace the base motor ( like bldc) with same gear box?
Do you have any idea?
EPIC GAMWER
That climber 👀
Very cool
Did you have any issues with jamming in the hopper or the power cells rubbing/sticking when you were intaking or holding multiple power cells?
We didn't experience this, but didn't have too much ability to test it because we only had two power cells.
Which reels you use to climb
How does that elevator for the climb work? It looks very compacted
The elevator is 3 PVC tubes stacked inside each other. They're arranged in a cascade lift configuration so lifting the bottom one lifts them all.
@@juliaschatz6715 what is inside the tubes? what extends them? Is it pneumatics?
@@benjaminlewis7024 A winch wraps up the first spool of rope. I suggest you read our technical white paper and watch the prototype videos as well as the technical walk through for more information.
@@juliaschatz6715 Love the 3 PVC tubes idea. Much easier and cheaper than a lift with aluminum tubes and bearing blocks.
Do you use pneumatics at all or have any tips for using them?
We use pneumatics to actuate the intake (0:13) and the control panel spinner (1:46), and to stop balls from entering the shooter (0:25). They are a relatively simple way to actuate mechanisms that have 2 fixed positions. You will need space for the compressor and air tanks, and will have to watch out for leaks.
1st, GLHF!
Did you buy a winch to draw up your robot for the climb function or make one yourselves? If you bought it, where can I find it (if it is a relatively cheap one)? If you made it, how?
The winch is made of a rod with a round exterior and hex interior that fits around the hex shaft of a CIM motor, and has three water jet cut flanges that fit around the hex shaft, one on either side and one in the middle, spaced apart by the aforementioned round exterior hex interior rod. The flanges have a hole in them for the paracord to tie to. The CIM's short hex shaft was extended with churro, held in place by the round/hex rod and a bolt running through its center hole to the tapped end of the CIM hex shaft. The middle flange keeps the paracord running around the right side of the robot separate from the paracord running around the left side, essentially allowing the winch to pull in both directions at once.
If you don’t have access to a water jet, hex wheel hubs tend to make good flanges for makeshift winches.
The gearbox for the winch is an old andymark one. Any one with about 15:1 and supports two cim motors should work
What rope did y’all use for the hanging of the robot towards the end
It's paracord
What motor and gearbox do you use for the winch system?
The climbing winch is 2 CIM motors on a 24:1 reduction and a 0.7" diameter pulley
If you don't mind me asking, what is the material that you are putting on that hook to stop the robot from slipping? Thank you.
Looks like surgical tubing wrapped tight around a hook
It is indeed surgical tubing
Karl Arnhold thank you, and where did you purchase this surgical tubing?
@@jonathanbacon3248 You can get it on McMaster: www.mcmaster.com/surgical-tubing
Hey! Matthew Preis my team just started frc and have no experience I was wondering if you and maybe some of your team could come to my school and teach us about how the robots work and some strategy and other things for a day? My school is Higher Ground Academy Secondary in Saint Paul MN Thanks
We'd be happy to find someone who can help you out! You can get in contact with the University of Minnesota robotics team by email at robotics (at) umn.edu, but I would also recommend you contact the MN FIRST regional leadership to get in contact with a local team or mentors that have robotics experience: firstuppermidwest.org/contact-us/
Absolute u n i t
How much does it weigh?
We don't have a scale, but I would guess it's on the high end of the limit ~130lbs
It seems semi autonomous . Am i right ?
Nope. It's entirely driver controlled.
I’m team 4122
How many balls can it hold at once?
We weren't able to test that due to a lack of game pieces. Theoretically it can hold 5, with one needing to be stored in the intake.
*laughs in ftc*
Clean up your audio. Other than that, nice reveal. Also, some jump cuts would be nice.
Bruh your robot is gonna send robots flying just because of the imbalance of the robot 🤦♂️
meh.
Meh? This is awesome!
What are you gonna do in three days?
meh.
@@pd9052 in 6 days, a robot that can hold more than two balls and make more than 1
how the hell do you guys do ri3ds? so much robot to make in 3 days
It's all done with intense discipline, focus, teamwork, and of course, passion.
just wonderin do u all have students that skip school for 3 days?? I cant imagine spending only like 6 hours for 3 days to make something this impressive
@@snoopy8350 Classes start on the 21st for us, so we were able to dedicate all of our time. We also had some UMN alumni that took time off work to help
It helps when you are still on break, but as someone who is on a design team in college and did 4 years of Student FRC it's very doable. It comes down to having people dedicated and passionate but also a group of engineers that are capable of breaking down tasks, delegating work and learning to optimize resources. It's not the ideal option obviously, but you can take the same tasks and get a robot done in -4 weeks with 2 weeks of practice! It can all be done!
