Robots that are "different"

[martin417]

This year, I have seen more similar robots than any past year I can remember. It looks like most robots have gone with some variation of roller collector and catapult, either a high pivot catapult like team Copioli, or a low pivot catapult like team JVN (most are like the latter). There are also a sprinkling of Boom Done style bots with el-toro. There are some exceptions, like the awesome roller shooter from 383, and the cool cannon of the Robonauts.

Are there any other "different" designs out there? I would like to see something different.

Excellent example! thank you!

[bEdhEd]

Not sure if you've already seen it, but here's our build season video with our robot reveal in it for "Freyja" which has a JVN style intake, but we opted for a back loading pivoting ballista/crossbow style launcher instead of a catapult.

http://www.youtube.com/watch?v=9KxsAfPwhHs&feature=youtube_gdata_player

In the past few years, notably 2012, 2013, and 2014 my team has done a design that breaks away from the norm of design of lot of other robots. We do this intentionally to challenge our students, and now with Ri3D we try to not copy their designs entirely, or at all. In 2012 we had a short shooter that could stack a robot on top for double or triple balances, in 2013 we had a tall disk shooter that pivoted and organized disks linearly instead of stacked in a bucket style hopper, and in 2014 we did our launcher instead of a catapult.

[Jibri Wright]

We also did a crossbow style launcher. I'll see if my team will let me post a pic today.

We also did a crossbow style launcher. I'll see if my team will let me post a pic today.
Given our relative inexperience (mostly have freshmen this year), using a more proven system enabled us to get a robot quickly done, test it successfully, and teach the freshmen members how to work the design process to a finish with minimal tool access (no access to CNC, plasma, 3D, adnauseum). Unique? Yep, we love plywood, Modulox transmissions and the AndyMark chassis! :) Different? Maybe....we got done and tested BEFORE "Bag and Tag" night was done! Did my team have a bunch of "stuff eatin' grins" when we were done? Yep! THAT was different!!!
See some of y'all at the Dallas Regional very soon.....

[ykarkason]

Here's our team's bot, which I think is quite different than some of the other robots I've seen thus far:

I think we have a somewhat unique design http://www.chiefdelphi.com/media/photos/39687?

[Jonathan Ryan]

http://youtu.be/uk7nVST1lAQ

T-rx 145 used the el toro intake, but went with a hammer/boot/5lbs of steel weights ball launcher.

Simple yet effective.

[MysterE]

Our difference comes in the how more than the what. We used constant force springs to tension our catapult, a pneumatic piston to lock the catapult down, and of course the articulating arms to lift the ball.

Watch out for The Sabercats (4146) at AZ and LV. They have one of those unique designs that's right down your alley. :)

This is our robot, I haven't seen any others like it, but there are probably some out there that are.

[Kingland093]

My team has a robot that's pretty different. It has a linear launcher powered by surgical tubing and drawer sliders for shooting and to pick up and load the ball, we have a claw.
there's a picture on our website

[fox46]

I like to think our is pretty unique. Can't post anything yet though until premiere night is over.

[LordMvfp]

Does a triangler bot count as different?

[Orion.DeYoe]

How can it be that no one has posted this!

That's about as different as it gets. I really hope this is what their robot looks like (but obviously aluminum and powder coated a gorgeous blue).

[brrian27]

I think ours is pretty unique! Circular base with a swerve drive train and wheeled shooter.

Check it out.

Our robot is turning out to be pretty different, although I didn't expect it to be. Check it out during premiere night.

[plasma_54]

Team 2403 uses a standard catapult, but we have a fairly unique pickup mechanism:

[Nick.kremer]

While 3512's design can clearly be traced back to a certain dominate robot from 2008, I think we have done a lot to make it our own. I have certainly not seen a bot with the same style of launcher as ours!

*Will be posting pictures and videos soon!

We used a standard pickup and catcher, but will have a surprise this year. :)

Also, we have this: http://www.chiefdelphi.com/forums/showthread.php?threadid=127021

[Whippet]

4301 went with an open-topped catcher (the framework of which can be seen here (http://www.youtube.com/watch?v=D2--1ZYx3nY&list=UUFYxi76cfN6WtpsAiZOQd-g&feature=c4-overview).)

We're also working on a combined pickup/release mechanism similar to 384 and 1086's 2008 robots. (http://www.youtube.com/watch?v=Ml9wfMRaAmU)

[wasayanwer97]

I haven't seen too many robots like ours.

We went with a passive intake and a passive catching area.
Shooter is a swinging "hammer" (I know I have seen a few of those though.)

[dipmeinaluminum]

Ours is not a copy
http://youtu.be/Bu5-NvMUQ-Y

[Chris is me]

There are a lot more design details in variations in the arm shooter class of robots. Similar form factor but tons of variety there.

I've seen a lot of cool catapult catching mechanisms too.

I expect the level of robot design parity to be similar to 2011.

[JohnSchneider]

Watch Dallas week 3...:rolleyes:

[BoilerMentor]

Our robot is very unique! We wanted to share earlier but since we were part of the FRC Top 25 Premiere we had to wait until now.

Check out Sea Cobra here:

http://www.youtube.com/watch?v=zfgvXcCyOnI

6 blue nitrile traction wheels that are 2" wide.
6 CIM VEX Pro Ball shifter 2.65x spread with 60:24 final reduction.
The 6" diameter shooter roller is powered by 2 RS550's in simile gearboxes to a 18:36 belt reduction.

We use a "clamp" pickup which allows us to place the ball into another robot. We also have a shooter that can shoot from 18ft+ and a 2 ball autonomous.

I'll show you mine if you show me yours.

But in all serious-ness, between 2008, build blitz, and Ri3D bots, there is very little that's actually different.

I will add, however, that the robots that are launching balls with wheels are very cool. My team ruled that design out due to the size of the ball, but props to teams for willing to give those designs their fair shake.

- Sunny G.

[Pault]

I personally think there is a good amount of variety. Maybe it's just me, but 3 different types of intake (horizontal roller, el toro, grabber) and 6 different types of shooter (pneumatic catapult, motor catapult, spring catapult, puncher, hammer, flywheels) is pretty good.

That being said, my team has an extremely unique design. We have never seen anything remotely similar to our intake, and only a few similar shooters. Plus, we have a couple of unique strategies that I don't see any teams designed for.

[Andrew Schreiber]

They opened up their shop to let a lot of local teams practice on their field, and they were very gracious in letting us see their robots, and they had team members who were eager to share with us the specifics of their bot. It's not like I posted a picture of their robot. I would NEVER do that. Anyone who hasn't seen their robot still has no idea how it actually looks, I can assure you.

And you respond to this graciousness with...

Maybe you should rethink your approach here lest others not be quite so gracious in the future. If they WANTED that information out there don't you think they'd share it?

Actually when people asked if they could see the robot up close/take pictures we said yes, with the specific qualifier that any pictures or other information not be distributed beyond their own team members.

In general it is safe to assume that if a team has not posted pictures/video/details of their robot it is because they have a reason for wanting to do so at a later date.

[Adam Freeman]

In general it is safe to assume that if a team has not posted pictures/video/details of their robot it is because they have a reason for wanting to do so at a later date.

I would echo this sentiment. It seems really odd to me that anyone would publicly discuss or reveal someone elses robot prior to the team itself revealing it or the teams first competition.

I'd be interested in understanding how someone would justify posting a photo to facebook or something like that without getting permission first.

Maybe I'm just getting to old.

Ours is a bit different. I hope that turns out to be a good thing. We are hoping to play a game where the ball never touches the floor (we have Toro sticks for when that doesn't happen - like most of the time). Our shooter is a variable speed, belt driven, linear rail gun. The top end consists of bounce-free Lexan panels that don't require precise throws/alignment.We don't have our own video, but we play a cameo role in 2054's reveal (by the way, they had our permission to include us in the video): http://www.chiefdelphi.com/forums/showthread.php?t=127044

You robot does a great catch! Your panels really do seem bounce-free. That ball just sets in nicely. I can't remember which team I saw that had a net, but a net seems to be the other bounce-free solution to catching. I think your difference will benefit you in your catches. I'm glad to see more teams with linear lauching mechanisms. Good luck!

[Trey178]

We do not have video posted of our complete robot yet, but we're using a 3-stage pneumatic puncher. With 7 pistons total, each powered by its own solenoid and tank, it fully extends in about 0.033 seconds. Look for the "Team 178 2014 Build" thread to see how we made it work.

I've always thought from the beginning that the challenge of Aerial Assist wasn't the robot, but the game. I'm far less interested in unique robot designs than I am in unique gameplay.

Seconded.

[bEdhEd]

I've always thought from the beginning that the challenge of Aerial Assist wasn't the robot, but the game. I'm far less interested in unique robot designs than I am in unique gameplay.

The game definitely was something that I saw as a challenge more than the robot, especially since it relies on other teams to maximize the score. Our philosophy now is that we make a robot that can win matches on its own, or at least do well on its own in the event that alliance partners' robots don't show up, or do not work on the field. But in this year's game, the curve ball thrown is that we pretty much have to rely on other teams for points.

There are some strategies, however, that use one robot and human players to gain points, so no other robots are required to gain points that may have needed two robots in a strategy, so there's still a good chance of a match win with one robot against two or three.

[Anthony4004]

Team 4004 has a very different method compared to most teams! We would have submitted a video for top 25 however our catapult arm broke and bent in half! With that we spent all day Sunday and part of Monday to rebuild it stronger, improve the launch design overall, and put it all back together. That didn't leave us with enought time, so we hope to use part of our 6 hours to make one, LEDs flashing and all :D with that, we will be introducing Our 2014 robot, Grimlock.




Teaser: All-in-one mechanism. Pickup, shoot, catch. (Well somewhat catch, that's up to our programmers :D )

[BEN35678]

The design of our robot is not that different then most just how we power the shooter is different. We use 6 cims which is connected to the shooter by chain.

I'd like to introduce you to Maddox. (https://www.youtube.com/watch?v=uGNU7D41eDQ) (Though more of the team is leaning towards calling it Atlas, despite my input.)

All said and done, it performs much better than we expected! (But the math worked out, so why not try, right?) I'm sorry to say we don't have a video of picking up, but there are a few pretty nice shots in there!

In case you were wondering, our pickup is used by two extensions of the shooter mechanism acting as arms on servo control. (Here's a picture of it a bit more put together (https://twitter.com/frc2605/status/433490389417226240/photo/1))

For me, the issue has always been how well someone does something, not just how creatively they do it. (Though there is definitely something to be said about effective use of unusual strategy.)

Are there any other "different" designs out there? I would like to see something different.

I have seen many new drivetrain designs this year. 148, 118, 624, 3847 , 488 all have many unique drivetrain designs.

With only a single task and no endgame, designs all start to look very similar.
The VRC Toss Up Game has more challenges and wrinkles than the FRC game this year. Ultimate Ascent and Rebound Rumble were two of the best FRC games, Aerial Assist has to still play out, but the design and build season has been a bit underwhelming.

Aerial Assist is more complex than Rebound Rumble and on par with UA in terms of in game strategy. Though we have been spoiled the last two years.

We are a the BoltBots Team 5040 and we are a rookie team with little experience . But our team built a wicked awesome goalie see our test
run . Sorry we don't have any slick production video to show off. Just this
video and some photos . The blocker center pole is 1 inch square steel tubing and has chain welded to the face of it . The
standard electrical channel supports the tubing . Extends to 112 inches in seconds . It can take a direct blow from the ball as hard as you can throw it and it deflect the shot . All these teams seem to be shooting great as long
as they have a clear shot at the goal. We may be the most hated team
out there for building such a beast . The ball shooter is a steel hammer that
swings around and hits the ball from the bottom . The ball picker is very simple like a fork lift style that also can be used to aim the ball at different targets.

[Sophia2605]

Our robot is one of the only ones I've seen that uses belts to shoot the ball. The little flipper arms at the bottom move in and out like little arms to bring the ball closer, and the two sides with rollers and belts are tensioned with surgical tubing. We also have a winch-type system on the bottom of the cradle that the ball sits in and the winch pulls the arms tighter or lets them go looser. We 3D printed about 100 rollers in total, including extras.

My team 3467 Windham Windup has a robot like no other I've seen. The robot is completely ambidextrous. We have dual ball pickups, and a "sled-uchet" shooter; half sled and half trebuchet. The trebuchet part is a low mass sling which allows more energy to be transferred back into the ball for shooting/passing.

I would consider our robot, team rembrandts, differend. It has a unique hinging design that I havent seen on any other bot. Everything on the robot is lazer cut and anodised orange for it's smooth look. Also it's shooter is a unique design although more robots use the punch method, it's retraction method is unlike any other. And instead of using a board were we all the electro is attached on, we use an electro box drawer so we can easally take out our electro and keep on programming even without our robot.

I haven't seen another robot this season that is very much like ours:

https://scontent-a-sea.xx.fbcdn.net/hphotos-ash3/t1.0-9/10177259_617951694967322_4721352311988398743_n.jpg

The design is symmetric, and the claw can flip a full 180 degrees for a double sided intake and shooter. The claw can be opened and closed with a lead screw attached to the back linkage bars. The shooter is drawn by a choo-choo gear mechanism, and the force comes from springs that are hidden inside the arms. The LEDs are indicators for the drivers to see which side of the robot faces them, since the whole thing is completely symmetric, and they correspond to green and red buttons on our custom control board that controls the position of the claw.

My teams (1425) robot is very different. We have a variarion on the roller collector. This photo does not show it but the current iteration has mechanum and omni wheels to direct the ball to the center of the bot. We have a kiwi drive which is uncommon. To shoot we have two vertical wheels (much like a pitching machine) and a pneumatic "injector" that forces the ball between the wheels. Packaging this all together was quite a challenge so we ended up putting the top shooter wheel on the back of the collector "arm".

With all due respect to 195, they have an incredible robot, the basic concept is similar to several teams this year (118, 971, 2590, 67...)

Show me another intake like the CyberKnights.

I haven't seen another robot this season that is very much like ours:

The design is symmetric, and the claw can flip a full 180 degrees for a double sided intake and shooter. The claw can be opened and closed with a lead screw attached to the back linkage bars. The shooter is drawn by a choo-choo gear mechanism, and the force comes from springs that are hidden inside the arms. The LEDs are indicators for the drivers to see which side of the robot faces them, since the whole thing is completely symmetric, and they correspond to green and red buttons on our custom control board that controls the position of the claw.

For a first year team your robot is extremely impressive! Do you have any videos of it in action?

I'd say that our robot was pretty unique

I thought our team's bot was somewhat unique this year.

One of the announcers called it a 'Flinger' at the W. Canada Regional and I rather liked that particular rendition of a name for our firing mech XD

[Briansmithtown]

Our robot deffently... Heck we won an award because how weird our arm was. We invented an arm this yeear, and won the creativity award for it.

Our robot(1318) has tower that extends the pivot joint for the shooter assembly 10" out of the frame perimeter to make room for longer arms while still having a wide intake.

[George C]

Our two 250 pounds force compressions springs were certainly "different". When the launcher was triggered, it went off with a bang.

[Clem1640]

We used a slingshot in lieu of a catapult. Good for short, high trajectory shots. Safety with a catapult was a key concern.

How bout this one? As far as I know we were the only team to incorporate both hockey sticks and an arm/catapult mechanism.

We saw Team 334 (http://youtu.be/VFUMrp5ir2I) (TechKnights) at NYC, with an interesting intake design which let them turn to face the ball without knocking it out of the way. They also had a pivoting slingshot which proved very powerful.

Who says you need a shooter or even a pickup to be competitive....

In the Western Canada Regional the yoke for the winch clutch, which was 3D printed, shattered just before the elimination rounds. We competed with our arms up and all we can do is ball in and ball out and play defence. We win the regionals and proceeded to St. Louise. Didn't beat the 254 2056 865 record of 346 points but pretty darn close with 325 points.
