It probably wouldn’t do much because the motors are capped at an upper limit. Also, I’ve tried the AA battery pack and does worse than a fully charged battery pack.
Yeah, that’s what I was afraid of. With a nerf gun, you have to remove the voltage limiter for the motors before it will do much. But i would assume that since they have more capacity, it would last longer than a battery pack.
Eh good point that makes sense btw is there an age limit for FTC like there is for vex?
Stupid auto correct, I meant frc sorry
sorry if this is a stupid question, but what is FRC?
It’s another robot program
oh (i dont understand the 20 characters thing)
FRC stands for FIRST (For Inspiration and Recognition of Science and Technology) Robotics Competition. It is a high school robotics program (sometimes you can get in at 8th grade) where you work with a team and build 125 lb. robots that play a game. It is very similar to VRC, but on a much bigger scale. And they play on alliances of 3 vs. 3 instead of on alliances of 2 vs. 2. It was founded in 1989 by entrepreneur and engineer Dean Kamen, but the first FRC game was in 1992. But enough about the history, and check out TheBlueAlliance which is a platform that hosts all the history of all the FRC matches ever played (although some it has no info about). It has thousands of match videos, etc.
I hope this answers your question.
FYI, I am on FRC team 973. Just PM me if you’d like more info (e.g. top teams, etc.)
I think that in its best state, a tray bot would be the meta for rise above. If someone built it perfectly, I think it would be very fast and effective.
Here are some ideas:
A flat base with the tray at a 45 degree angle on the robot when at rest.
On the inner back plate of the tray, there are tank treads with 2 pitch standoffs on them, it would be sort of like a reverse ball intake from squared away.
Then, at the top of the tray, there should be an extendable part (about the size of the third riser) that you would extend at the beginning of the match.
So, the tray intakes the risers at a 45 degree angle and then it would speedily drive to a goal, and tilt the tray up to a 90 degree angle, while simultaneously running the intake at reverse.
In conclusion, that would use all six motors, and would be more effective than any other design (provided the operators have designed an effective program and can drive well).
Just out of curiosity, can you send some pictures or proof of concept?
I understand that this is just what you think, but I’d be interested to see if it really is the meta, or if it just doesn’t work at all. Thus far, I haven’t seen anyone successfully accomplish a tray bot (like TT) for Rise Above, and we unsuccessfully tried it at one point, so if you get it to work, I’d love to see it.
For us, the problem was that the risers aren’t cubes and they’re massive, so they don’t pick up well, but I’d like to see it if anyone else gets it to work. Good luck!
Yeah, due to the software voltage limits on the Smart Motors, you won’t really get any better performance from using the 228-3493 Robot AA Battery Holder than using the 228-2604 Robot Battery included with Super Kits.
While 6x fresh ~1.5V Alkaline AA cells would create a ~9V battery pack, there are two concerns:
- The extra voltage is “ignored” by the motor due to the software caps
- Alkaline batteries are not great at handling high sustained current draw (such as over 1 A for AA size). “Heavy Duty” aka Zinc Carbon batteries are even worse.
Rechargeable NiMH AA cells are typically the best rechargeable AA cells for handling high sustained current draw, but these are only ~1.2V each.
6 x 1.2 V = 7.2 V, which would yield the same voltage between the Robot AA Battery Holder and the rechargeable Robot Battery. This isn’t a coincidence, as inside the 228-2604 rechargeable Robot Battery, there are six AA size NiMH cells that are permanently welded together into a pack.
So at best, a Robot AA Battery Holder with six rechargeable AA NiMH cells inside would be basically identical to the rechargeable Robot Battery. The only area which might be slightly improved is the mAh capacity, which could yield slightly longer run time between charges.
If you watch some of Project Farm’s videos on rechargeable AA batteries, you may find some brands of AA cells may give you slightly larger mAh capacity than the 2000 mAh cells inside the IQ Robot Battery. So if you have a ton of these AA cells and AA battery chargers around, you might need to recharge your batteries slightly less frequently by using these.
Just in case anyone was interested, here is the link to a live in-person VEX IQ Rise Above competition webcast if anyone wants to watch and maybe get some robot ideas from it. Here is the link to the event on robotevents.com.
Please don’t fill up the discussion with things that don’t add to the discussion or put down others’ ideas. Just as a friendly reminder, please remember T.H.I.N.K. before you post.
T.H.I.N.K.
Yup, especially the H.
Have you guys seen this video yet? Probably not,it’d on BiliBili. Be careful on this website, as it may want to:

Anyway, here it is, a maxout in teamwork!
BTW, thanks @FRC973 for showing this.
@Noah10851B wait, they didn’t switch drivers halfway through! do you not have to do that this year?!!
Nope:
YEEEEEEESSSSSSSS!!! We have been trying to get my other coding teammate up to date on driving since the field is at my house. Thanks so much.
also why does it say the most recent posts are an hour ago?
