Rules Discussion / What is "controlled translational movement"?
« on: January 27, 2016, 02:29:57 pm »
The SPARC rules define controlled translational movement as "...being able to traverse in a manner such that the net movements of the robot are in a linear direction." This seems to be saying that as long as a robot is capable of moving in any direction (i.e. not just spinning in circles) that it should not be counted out. We ran into a situation at the last Kilobots event that has us a bit confused.

In the above fight, Killer Lotus spends about 20s or so on his back, moving ever-so-slightly due to the vibration his weapon was generating. We did not count him out at the time but reviewing the fight now we're wondering if we should have. There's no doubt that this movement is translational, the question is around whether or not it was "controlled."

Does controlled mean that the robot can start or stop the movement? In my opinion that's not good enough, but if one were to blindly follow what the rulebook says, it would probably qualify. Personally I think the "control" should refer to the direction of the movement, i.e. you're able to control the direction in which you're moving.

Just curious to see what everyone else's thoughts are!

My general opinion is that if there are actual voids of space inside your bot you're better off making the bot smaller before filling those areas with support material, then using the saved weight to add armor to the exterior of your bot.

Control makes more sense than aggression if you look at the SPARC judging guidelines, specifically this paragraph:
The primary means of scoring points in this category (control) involves using elements of the robot or arena against the opponent in a manner that doesn’t directly involve the weapon system of the robot causing damage

However, it seems crazy to me that Pinky/Brain could win a JD in a match where Brain is pushed out. I would almost propose that a pushout count as both damage and control just to make it harder for the multibot to win a JD in this scenario. Given that in a 1v1 a pushout is an insta-win, it seems wrong that it only count towards 35% of the JD (6 out of 17 possible points).

If you think about it, it could almost even count towards aggression! If Brain is pushed out, that 74% of the bot that can't show any aggression for the remainder of the fight.

I was judging the LL v Pinky/Brain fight and had the same question about how to score it when Pinky was knocked out. Kurtis suggested that it count as control instead of damage.

Curious, did you ever solve your weird drive issues? I ran into something similar during an event this past weekend, basically either one or both of my drive motors would randomly reverse direction. Stranger yet, it was happening on both of the bots I was driving. My setup was mostly the same on both bots: spark motors, tinyESCs, OrangeRX tx/rx. I did eventually swap out the OrangeRX radio for a HK one and this noticeably helped but the issue did eventually come back.

My dad has sent me on a quest to make my robots better. So what do you guys use to mount silver sparks? As of right now, I use the FingerTech bering blocks with the 2-56 Button Head Screws. What would you guys suggest to replace/make this better?

Are there any particular issues you're having with the FT bearing blocks? I've always found them to be pretty solid.

True as the quick part. Almost all robots have screw heads to attach to, or magnets at my local events.

That's a gamble as to whether the other robot's magnets will repel or attract you though.

So what if you had 3 bots where one weighed 50% and two weighed 25%? Seems to me the rule should apply in this case as well where you'd need to choose one of the 25% bots to be the "heavier" one, no?

So when you register your bot you dont have to buy your own weekend pass. And the fighting is a two day thing right. Like you have to fight both days right?
Correct, if you register before August 21 you don't have to pay for your pass.
Also correct that there will be fights on both days. If you're eliminated on day 1 you might not have to fight on day 2, but there will still be grudge matches and rumbles etc.

I'd hang on to them if I were you. It's always nice to have a little stockpile of parts for when you want to throw together a new bot.

The polycarb wedge it comes with is 3mm thick, and titanium is roughly 4x as heavy as polycarb, so yes a 1mm titanium wedge will be slightly heavier.

Thanks Kurtis! I didn't think I'd be able to get to the set screw once the tire was mounted, so that's good to know and should make it easier for me.

Neither did Kurtis until someone point it out to him. ;)

Well I thought it would be kind of neat to have a kilobot that could also maybe compete as a beetle with some bolted on armor and a heavier weapon. But the idea I had in mind for that was a spinner. So yeah.

Sawblades at 30lb class do not cause kinetic hits, but they do at insect the insect level. (Hyper Ninja for example)

We actually did allow saws originally a few years ago, then we argued over it, and then we banned them.

Ah, interesting. I'm sure that's somewhat dependent on the number of teeth though? Perhaps we could allow them with a TPI restriction or something?
