DΣLTΛ IV - Iteration 3 Reveal

Couldn’t have said it better myself

Since we are a defense bot and have a strong drivetrain, right at the beginning of the match, we “disable” or eliminate the ball bot from being able to score the flags, enabling our partner ball bot to score freely. I cannot get into further detail, but it has worked fairly nicely until finals of our last tournament, which we lost by 2 points simply because the wrist motor port blew out.

I can definitely see that doing well. I typically had our partner come out capping as many as possible. This gave our opponents the choice of either getting overrun by caps or to go and try to de-score leaving me with a 1v1 against our opponent. So it has an end result similar to yours, because while you’re playing defense you’re not scoring, leaving your partner to deal with the remaining opponent.

At the competitions we have been to, we are almost always faster than cap descorers. so in the time it takes a team to descore a cap, we are able to score 2 caps. in almost all of our matches we have had this year we were able to score all the caps.

this is why I love the robots this season, there’s more variation and innovation going on this year than any others I’ve seen. but I predict that the final worlds match will be between 4 practically identical robots, as It always seems to be…

Agreed, but since nobody can seem to agree on any single design, probably more.

This is a wonderful cap robot. As others have mentioned, however, with so many motors on your drive, I don’t see why you wouldn’t speed it up. You can score caps more efficiently than every other team I’ve seen, so if you’re able to run around the field and ensure no one is able to descore those caps, you could become even more effective.

Since everyone’s talking about it, do you guys mind sharing your drive rpm? Is it standard 200?

We have a big bumper on the back of our robot for a reason :wink:

The drive is 6m 200 RPM. We did 600 RPM before and it was a bittttt toooo fastttt XD

Haha I’m sure it was, we even find 200 rpm a bit touchy but our bot is probably fairly lighter. Are you guys considering gearing up for 300 ish?

Though speed does seem like it would help, it actually is a disadvantage in many ways. we tried 600 rpm (We ordered 4 600 rpm gear boxes when we got v5) and it ended up being too fast to the point that we had to do a ton of micro-adjustments which ended up taking a ton of time. then we switched to 200 rpm. 200rpm is not only still fast, its controllable. it also provides us with more torque allowing us to push robots more effectively.
On a completely different note, our robot in the reveal isn’t going its fastest. we are pushing it about 2/3 of the speed. in competition we go 100% speed to get around the field quickly to block an opponent. but we do 2/3 speed when trying to score.
v5 is a new system to us and we are still feeling out the robot. by state, we should be going 100% speed while scoring as well as driving around the field.

We do something similar, I just wondered if you could push the speed a bit more with 6 motors. Sounds like you guys have it figured out pretty well at least for the time being.

For right now I think we are fine. at the last tournament we were at, we were the fastest robot out there. but who knows, maybe towards the end once we are comfortable with the speed we are currently at, we will increase the rpms.

Not to mention that adding gearboxes to increase speed adds bulk and complexity to the robot’s most important subsystem.

Bulk
-Not really an issue with this robot, there seems to be plenty of space for a gearbox?
Complexity
-A drive gearbox complex? I’d have to disagree with u there, especially for a team of this caliber

True, but it’s just one more thing that could break. It in and of itself is not complex, but it adds complexity. Not much, but a little.

I would think this would be worth looking into, even if there has to be a button to switch speed modes. But not until they’re doing everything at 100% speed. As stated, they’re comfortable with it as is.

Also, speed is counter to torque. Adding excess speed that won’t be used decreases their effectiveness in pushing matches.

Hi guys what made u use plexiglass(PMMA) instead of metallic vex parts?

I’m pretty sure for weight purposes and also because the lexan is cut in a specific way that is easier to do with lexan than vex metal. Also for the fact that cutting metal in that way would probably make it unusable again. These are just guesses tho

We use it because it’s flexible and it’s inexpensive. Not to mention it’s easy to form. It also is super light like NightsRisario mentioned.
