My intent of this thread is to gather information for as many robots as we can for everyone to benefit from.
Please try to keep chatter and discussion to a minimum, just robot information please.
So, lets hear information about your robot. Please be honest about you robot and say what it does, not what it could do.
Here’s a start:
Team 229 - Division by Zero
Picture: scoring & ramps
4ft 116.5lbs
Drivetrain:
2-speed Andymark Shifters
9.8ft/s in high gear, 3.8ft/s in low
4" IFI traction wheels in a 6-wheel drive, lower wheel centered, configuration
ground clearance is ~ 1.5"
Arm:
high jointed arm which reaches all three spider legs
Gripper:
Roller gripper with top and bottom rollers independently powered to allow tube pickup, rotation (over 270 degrees), and release.
2 position pneumatic wristto allow tube pickup, and tube “stowing”
Ramps:
Two fold out ramps that allow two robots to raise themselves 13.5" from the playing field surface, these have never been climbed in competition
Drivetrain:
4 small CIMs with 4 BaneBots 56mm planetary gearboxes
AndyMark Mecanum wheels
ground clearance > 3" (more like 4ish)
Can climb ramps the wide way only (requires around 36" of ramp width)
Plays WICKED defense (have prevented high scoring teams that usually score 5-6 in a match from scoring at all). The mecanum helps with this.
Fast. Not sure on measurements in ft/s, but I can get this info and edit it in later.
Ramp:
1 ramp with extended platform of over 12 ft.
Ramp at 14.5" No chance of loss of points due to sag
Requires 2" of clearance minimum to climb
Has side rails to prevent driving off of ramp/platform
Has been climbed numerous times in competitions, including by high scoring teams like 25.
So in short, a large aircraft carrier with a wicked defense and mecanum. We can EASILY hold 2 bots (we have actually fit 3 at 14.5", and 1 partly up the ramp at 4" … but thats besides the point. Our highest score in a match was 316, and we were AGAINST one of the winners of the philly regional!
Arm:
Twin-globe motor powered shoulder joint
Single-fire extension at beginning of match (latches in extended position)
Simple, Durable
Gripper:
Pneumatic 2-position Wrist
Pneumatic Grabber “pinches” tubes
Single point of rotation
Autonomous:
Dead-reckoning scoring has worked in the past
Camera/sensor aided scoring is looking promising
Strengths:
Effective and rapid scoring
Quick ground loading
Long extension of arms allows for scoring through (and even over) defense
Experienced (all senior) drive crew with 3 returning members
Easily climbs virtually any ramp/lift
Can remove spoilers
8 wheel drive with gyro steering
2 2.5 inch CIM motors
6 inch AndyMark kop wheels
Ramp
78"x37" (deployed) 12 inch high table with 36" long 20 degree ramp
Aotonomous
Gyro stablelized drive to opposite end of playing field with right or left 90 deg turn depending on starting location
Strengths
+Effective defender with ability to defend all tiers. (Shutout opposing alliance 76-0 & 92-0 in Colorado quaterfinals)
+Proven robust and reliable double ramper
Search Delphi for 1583 to see videos and more pics
Links to match videos, photos, and FIRST’s team information for each team can be found on The Blue Alliance’s Championship Portal which will have more and more information added to it over the week left until Championship!
Autonomous:
3 total
One Dead-reckoning Defense
Two auto’s that block front of rack
Strengths:
Effective and rapid scoring
Quick ground loading
Strong drive that allows us to back defender up and score on rack
Defense
experienced drive team
Easily climbs virtually any ramp/lift
Gripper
Pneumatic open/close
Had toruble holding tubes at FLR so gripper has been redesigned
Only 1 tube placed on rack during a match
Points of success
Can play good defense
Climbs ramps well
Powerful drivetrain
As of now gripper stinks but should improve with new design
Experienced driveteam and coach
Pretty bumpers
This post might make our robot sound not so great but I wanted to give you guys facts, not hopes and dreams. Not sure how we’ll do on the grand stage but I guess we’ll see. I would probably pick us in the second round of choosing partners as of right now. However, we may move up to a top pick once the new gripper is installed.
Arm: (pic1pic2pic3)
Legendary team 60 Arm.
Each Joint Driven by a small CIM with an AM planetary.
Can score on all 3 levels.
Can score 8 undefended. Hasn’t happened in a match, that was on a practice field. 5 in a match has been done though (while wasting the last 20 seconds or so)
Gripper:
Grabs tubes from outside, strong grip and allows for a lot of missallignment
Autonomous:
Dead-reckoning/Prep for pickup
Strengths:
Drivetrain can climb any ramp out there.
Can Score Quickly.
Rarely Drops tubes.
Great Defense.
Can put our open grabber over a spoiled spider leg to keep it from being despoiled (sounds weird, but this may prove useful)
We are looking to be a versatile 3rd pick. We can round out any alliance, we can play great defense if that is what is needed, or can pitch in on offense/protetcting a main scorer.
PNW Regional: 5th seed alliance captain, semi-finalist; Rockin’ Ramp award from team 1510
Silicon Valley Regional: 1st draft by 5th seed alliance, finalist; Engineering Inspiration Award
Autonomous Mode –
Defensive runs to the other side of the rack
Drive –
6WD w/ 6" AM kitwheels in the middle and 6" AM omniwheels on the corners
CIM per side w/ 17.5:1 gearing; anecdotally holds its own against most teams, but we play smarter defense than simply shoving people around.
6 ft/s top speed
Lifts –
Two independently released and actuated lifting mechanisms (for good reason that we’ll tell you about when we work with you)
“Buzzer Lift”-capable – requires approximately one second to release lifts before buzzer sounds
Independent lifting action allows us to lift one robot or two with no effect on performance and to do so at different times. Lifts react against floor, not our robot and are supported along their entire ~4 ft. length.
Will not tip (in play, at the end, with robots on it, without robots on it. If you manage a way to tip this robot over, I’ll give you a dollar. If you do it on purpose, I won’t give you the dollar, however.)
Large lifting surface of 38x44" on each lift – accepts wide- and narrow-bodied robots and flop-down robots. As long as your center of gravity is over the white of our lifts, we will lift you.
Front-facing entry for last minute access – there’s no need for teams to enter the home zone, turn 90* and line themselves up with a narrow ramp as with most machines. Simply drive forward or backward onto our lifts.
If you move, we will lift you. Seriously. I know Jeff wants honesty and this is it. If you can’t move, come find me and I’ll help you fix it.
Hard stop at back of lifts that allow bumpers and frame to overrun our platforms while still stopping wheels.
… but thats besides the point. Our highest score in a match was 316, and we were AGAINST one of the winners of the philly regional!
