Over the past week, My team designed, built and competed with our robot, named Samwise Gamjeff, simply referred to as Jeff. This is my reflection on the build, going over what I used and what I learned from my first competition. I hesitate to call it a Reveal, as it won't be competing in any tournaments (we had members on the team from several local schools so competing would be logistically difficult), but I believe that this could help some people find inspiration for their robots.
Note 1: We had trouble at one point with a ball getting stuck under the robot and high centering it, this could be remedied by either putting a flat plate on the bottom of the robot or by putting more barriers around the intake.
Note 2: The intakes could have been linked together instead of using two motors, but due to the fact we were not trying to budget our motors, it was just easier to use two motors.

This is one of the best reveal videos I’ve ever seen. The video and audio quality was excellent, and I really enjoyed that you gave an explanation that included ideas on how to improve. Not only will that be beneficial for teams watching reveals for ideas, it’s also a great way to practice for talking to judges. All in all, this is extremely impressive, especially for only 4.5 days, hope you guys do great this season!

Thank you very much! This isn’t a style that a lot of people in the community use, so it’s something pretty unique in that regard. My building mindset is one of constant improvement, so going over the flaws and ways to improve is something that I constantly do. It was a very short time scale, but that can be very beneficial at times, putting the pressure on, and could potentially be used even in a team setting to encourage quick development of ideas that can be refined later. I hope your team does great this season as well! :D

Nice job, My team used the same idea, and mostly had the same problems. We attended a competition just on Saturday, in Massachusetts. We did pretty well. I liked the video. It was really good.

Good explanation and voice over

Great robot, even better video👌

@aleyssa2701 5 лет назад

Our team tried to build a dual flywheel I will system but we didn’t think it was possible so my teacher told us to look up videos to see if there are any to fly was in the big turning point game and so this is a really good video thank you I will use this for a reference a lot

Thank you very much! If you have any questions feel free to ask!

Great Vid! quick question: When y'all coded the auton, did you use any vision sensors/encoders to identify your color depending on what side of the field you were on, or just assumed that you'd be on one side of the field and adapted your code to fit with that side of the field?

@KeplerElectronics 5 лет назад

We coded one side, and then basically reversed everything and tweaked. We had a potentiometer to choose what color autonomous we were using. If I remember correctly, one of the two autonomous programs was able to get the middle flag and the other one couldn't, but that could have probably been fixed with more tweaking, but we didn't have time.

Nice

@eugenechoi9146 5 лет назад

how did you mount the entire flywheel mechanism and finned wheel intake transport? It looks crazy how you guys managed to turn that huge mechanism on a single pivot point! How did you do that??

@KeplerElectronics 5 лет назад

The main pivot was a simple axle running through the a set of holes at the far back (the furthest back if I remember correctly), with another pivot up with the aiming mechanism.

@victorsuarez9424 6 лет назад

How did you guys do the code for the potentiometers? Nice build btw.

@KeplerElectronics 6 лет назад

We had some help on the code from the counselor, but essentially, it said If potentiometer < 2000 then blue autonomous If potentiometer > 4096 then red autonomous. That second one may have been any else if, but that’s the gist of it.

@sillysock45 6 лет назад

How hard was it to aim? Did you miss often or was it easy once you had some practice.

@KeplerElectronics 6 лет назад

It got easier with time, but as with everything, rushing and pressure can make it more difficult to aim for sure, but all in all it was fairly easy.

@supperKingofworld 5 лет назад

How did you make it so that platform could tilt i would like to copy that for my inclass project and looking at the photos only get me so far.

@KeplerElectronics 5 лет назад

Its essentially a really short linear slide, with a pivot at the top and the bottom. It's important that the slide pivots, otherwise it won't work. Let me know if you have any questions. :)

@canisterbottournament 6 лет назад

can someone help me out cant find the answer to my question anywhere: so I know you have a certain zone to extend in but you cant extend outside the zone so if that's the case can you come out extended? I assume the answer is yes because on the video reveal the clawbot had its claw extended outside the zone and was wondering if maybe we can come out extended... like extend in the zone then go out the zone but dont extend back... am I wrong?

@lennytate4246 5 лет назад

Normally your robot can start in 18x18 and then extend to about 24-36 so depends

@agliacci 5 лет назад

You can only be expanded in the expansion zone. Once you are out of the expansion zone if you are above 18 inches that would be against the rules and you would likely be DQed

@cd2320 5 лет назад

Horizontally you can expand up to 36”, My team has a rotating claw that falls down during autonomous; however you can’t exceed 18” vertically except inside the expansion zone

@jams8728 6 лет назад

Was there any reason your team decided to build a robot for flags over posts?

@KeplerElectronics 6 лет назад

The reason was basically that I had been experimenting with flywheels before the camp started, and one of my team members found the video by Blake farmer that had the flywheel mechanism, so it just seemed like the thing to do.

usas 2 motores para tus ruedas que lanzan las pelotas?

@KeplerElectronics 5 лет назад

nosotros usamos cuatro motores correr nuestra rueda mosca. Perdón yo no hablo Espanol, yo solamente tenido dos años de espanol en la escuela. =)

@mikesfordxl 6 лет назад

Do you have information on the camp you went to? I am a teacher and this sounds like something I want to try and host.

@KeplerElectronics 6 лет назад

It was a five day camp where students came at 8:30, built, programmed and practiced until 4:00 where they cleaned up their workstations. Lunch was provided and students were split up into groups of three or four. Each team had their own parts but were free to ask other teams for parts. Day one was building, as was day two. Day three was driver control and building, and day four was autonomous and building. Day five we continued programming, competed in mock matches and eventually competed in the “official” matches. After the matches, teams disassembled their robots. Also, there were plenty of tools on site to allow students to cut and drill metal to size, and there were instructors to help teach students how to do more complex things and tool safety. Any other questions? :)

Kepler Electronics do you have a link to a website or a contact for the camp?
