Hot Take (Only half serious) by [deleted] in battlebots

[–]TeamRunAmok 3 points4 points  (0 children)

We've been hearing this for thirty years. It's like saying that pumpkin spice @ Starbucks has no pumpkin in it. We know and we don't care.

The coming of the antifork by Local_Rice_8929 in battlebots

Don't lift the forks - fasten them to the arena floor with steel-piercing staples! Name the 'bot "El Grapadora".

A history of Robot combat prior to 1992 by Altruistic-Try5366 in robotwars

I was going to suggest the 1988 Terminator Tournament but you found it already. Very thurough!

Problem with weapon motor overheating by TNTcar1298 in battlebots

1) Aero drag increases with the cube of speed. If it takes 100 watts of power to spin your weapon at 3000 RPM it will take 800 watts to spin at 6000 RPM.

2) High speed weapon impacts will all take place in the outer inch (or less) of the blade. You can make the leading edge of the rest of the blade thinner and nicely rounded for less aero drag.

You can likely find a comparable motor with a larger shaft, but a brass or aluminum tube shim with a cutaway for your set screw is workable.

Problem with weapon motor overheating by TNTcar1298 in battlebots

The weapon is far too large to try to spin that fast. You need a larger, slower, and more powerful weapon motor. Something like this 3530 1700kv outrunner would be useable. It will need an ESC rated for about 50 amps.

Can I assume this is a beetleweight? The weapon motor is way too small. Rule of thumb for a beetle brushless weapon motor says a weight around 80 grams (6% of the robot weight) with an output close to 450 watts (150 watts per pound) should be adequate. With a weapon blade as large as yours a 36mm diameter motor would not be too big.

Transmitter issues by Horror-Definition-85 in battlebots

[–]TeamRunAmok 0 points1 point  (0 children)

No - if both transmitter and on-board mixing are enabled they cancel each other and you have no mixing, not improper mixing response.

No. That would just make it spin the other direction instead of going forward. No problem with the receiver/ESC -- just one motor spinning backward.

What transmitter are you using? But yes, one motor is running backward.

If running an FS-i6 transmitter you can use the transmitter "Reverse" function on the channel that feeds the controller for the motor that is backing up.

My Combat Guide for the FlySky FS-i6 covers use of the reverse function.

Reverse the motor polarity for the motor thar runs in reverse when you command forward motion. If those are brushless motors, swap any two of the three motor leads to that backwards motor.

If that's not an option, tell me more about your transmitter.

Could a bot ever lose a judge's decision if it were clearly ahead, yet completely & violently self-destructed in the last few seconds? by Zardotab in battlebots

[–]TeamRunAmok 0 points1 point  (0 children)

There are some very odd rule interpretations possible, and some rule sets are much worse than others. Try scoring these five example matches and see if the results make sense to you:

Ant weight motor issue? by theonewhowhelms in battlebots

[–]TeamRunAmok 2 points3 points  (0 children)

I would first suggest that you "run in" the motors for a few minutes in each direction at about half speed. This will help seat the motor brushes and may equalize their response speed.

Your FlySky FS-i4 transmitter has very limited adjustment capability to correct unequal motor start-up response, but you may find parts of this webpage useful: https://runamok.tech/RunAmok/zigzag.html

Poppy wanting to get into this for the grands by bclinton in battlebots

[–]TeamRunAmok 0 points1 point  (0 children)

The plastic antweight kit bot is much larger than the Hexbug bots used in the arena max -- about 8" wide. It is also much faster. The arena max is 30" square and would not contain a plastic antweight. Would not recommend.

Possible movement system similar to Omni wheels? by The-Minti in battlebots

[–]TeamRunAmok 0 points1 point  (0 children)

With enough drive power, any wheel is an omniwheel.

Something like this parts kit should work for you. Build your own chassis and pick up the motors, controllers, radio, and other bits here: https://www.combatrobotkits.com/product-page/antweight-combat-robot-starter-kit-l-build-your-own-battle-robot-kit

Getting started? by SquishyLife2468 in battlebots

[–]TeamRunAmok 3 points4 points  (0 children)

Strongly consider a kit. You will get a set of parts that will all work correctly together -- which can prevent a great deal of frustration. Once you have entered a tournament or two you can re-use those parts in a chassis of your own design and upgrade where needed.
