Using Mech Combat To Hone Engineering Skills 59

jjp9999 writes "Mech Warfare is a mix between Battlebots and MechWarrior, only without the fanfare. The teams around the competitions include engineers and professionals in robotics, and the games are — aside from being an homage to their love for science fiction — a way to hone their skills in the field. Andrew Alter, roboticist and one of the mech pilots, said the competitions are taken as 'an engineering challenge,' noting that while they do compete, 'Having this mix of skill levels and demographics is really great to see, as information and ideas tend to flow freely. We're also solving practical real-world problems like being able to stream video over Wi-Fi in high-interference areas. It's not nearly as easy as one might think.'"

      I know, right? In every game from MW2 onward, once I got to the point where I could deploy a Timberwolf/Madcat, the rest of the mechs became uninteresting. I played with the 100 ton mechs and always came back to the Timberwolf. Best combination of maneuverability, firepower, and armor than anything else out there.

      In ... MW4, I think, there was a MkII you could play for a couple missions. Heavier and a little slower, but still better than any 100 ton class. And you could reduce armor, upgrade the engine and have almost the same speed and maneuverability as a timberwolf with increased loadout.

      After playing the games for years, I loaded up every mech (at the point where it became possible) with as many light gauss rifles as it could hold, and sniped while out of range of 90% of the game's weapons. It made the games absurdly easy. I suspect that's a programming or conceptual weakness in the game.

      When I got bored with Mech Commander 2, I played the game with the smallest, lightest scout mech, and found what I think is a loophole in the game. It's absurdly easy to win with a flock of small mechs against a few larger ones. (Although it takes a little more strategy.)

        I was all about the Daishi (in 3, at least). The lowest profile of any of the 100 tonners. I equipped it with four PPCs, heat sinks, and loads of armor. It could take a lot of punishment and one alpha strike would nearly make the Daishi go nuclear but it would instantly down any mech. Bonus: firing the alpha strike at anything above 0 heat. Having a thermonuclear suicide bomb as a last resort weapon is always a nice touch.

        • It is in fact all about the Daishi from 3 onward. It is especially compelling in 4. Even now that the game (which is free!) comes with a metric assload of 'mechs, the Daishi is still one of the best by far. It can carry and functionally fire 6 ER LLs in most terrain conditions and you can load it up with autocannons and light gauss for those desert maps. and it is relatively difficult to headshot.

          • I disagree. A madcat can easily beat the slow ponderous hulk of a Daishi in a fair fight. It can't turn quick enough, and it moves forward slower than a madcat can move backwards. It's only competitive if your opponent decides to stand and slug it out. Which would be moronic.

              I play it more like tank combat. Less the "main battle tank flying over a hill" type, and more the "quietly creeping up a hill, just barely exposing your turret, and popping the unsuspecting fuck of a Wehrmacht tank crew with an AP shell" kind.

              It's kind of like whack-a-mole, only the mole has particle-accelerators for hands.

              • Yes, you have it exactly. My favorite tactic with the daishi is to set the lasers to individual fire and then wander back and forth over a ridgeline. As I come up onto the enemy's side I fire each CERLL in sequence to keep them dazed and unable to shoot me, then drop back over the ridgeline and cool down. fIre the lasers faster than you would for continuous fire to get that pause while you're behind the hill. I have an average kill ratio of about two mad cat MkIIs to one of my daishis exploding. I was regul

                • It's been awhile since I played the game, but I'm pretty sure that the light gauss rifle had a longer range. I have seen the tactic you describe, but you can't fire without exposing a weapon, and if one goes after weapons instead of trying to pound on the thick armor around the cockpit, it's pretty easy to disarm the big guy. It takes more finesse, but bigger is not always better.

                  • The thing is, it's provably easier to get the hit on the arms of the mad cats because they stick out more, and the large lasers keep your opponent rocking to the point where most people can't hit you at all. It takes a little practice, but I used to play a whole hell of a lot.

            • A madcat can easily beat the slow ponderous hulk of a Daishi in a fair fight. It can't turn quick enough

              By turning the legs AND the torso at the same time, EASY if you have pedals and I do, you can turn quick enough to hit anything slower than about 96 kph any old time, and if you strip any Mad Cat or MkII down that far it's a tinderbox or it's toothless

              • Just use a three axis stick. I'm a Daishi fan myself, and have never had a maneuverability issue, but I have to admit never playing against humans. If someone is trying to get behind you one thing you can do is turn while backing up, it makes it nearly impossible for a mech even twice as fast as you to get behind you.

                I do like how the different mission scenarios force you to optimize for entirely different things.

                The problem is, after you get to the end of your turn radius, you're limited by how fast the chassis can turn, and a mad cat can walk in a circle faster than that.

          Well, you can only go so far with many things on-board. Yes, you can try to smash everyone with a 36" 4-legged robot (maximum allowed) but there's probably a battery penalty for playing that game. Same with the jammer, the more power you put on your jammer the more effective it is, but more power consumption.

          • The main problem with jamming is that it is meant to "simulate" piloting such a mech from in the cockpit (and contestants aren't allowed a direct view of the battlefield, which they would have in such a situation even if they were jammed). If there was a way to selectively jam signals so that you could see, but any other signals were jammed, I imagine it would be allowed.

          • Why not allow people to look around search for techniques that improve the reliability of the device and also cases of autonomy where the system maybe completely disconnected.

            Like I said, they're trying to simulate mechs that either have human pilots inside, or are completely autonomous. That's why the restriction on the pilot's view of the arena, and the restriction against jamming -- the radio connection between pilot and mech is "out of context", you see?

            It's the same reason a non-harmful way of disabling the actual human pilot standing outside the arena isn't allowed.

          • The problem with a frequency jammer is that disproportionately more difficult to overcome than it is to implement. These are guys building their mechs as a hobby in their garage, not well funded defense contractors. A jammer is trivially cheap to implement and has a low enough battery draw that it may as well not be there. On the flip side, overcoming those effects really is not possible with commodity hardware - an off the shelf WIFI or Bluetooth transceiver will simply stop working - it takes significant

    My initial reaction was "Why the hell are they all using legs instead of treads?"

    Then I checked their rules [mech-warfare.com].

    Mechs are to be true walking robots. Legs must be servo/actuator driven. No cam-driven, wheeled, or treaded configurations (except in the beginner league).
            Mechs may have up to 4 legs (Unlimited in the beginner league).

    So that explained to me why they were using such ungainly configurations.

    Some of the other rules on the mechs were about height, limitations as to leaving parts behind to hinder/causing damage to the arena (which I think would be pretty cool a function to build in honestly), and most interesting to me, control. The gist of it is that robots can either be autonomous OR controlled remotely. The kicker? Remote control can only be done if you have a wireless camera mounted in the "cockpit" area to control it. Which is pretty friggin awesome in my opinion.

    To someone's talk about jammers...

    In all weapons classes, weapons designed to interfere in any way with an opponent's camera or wireless control are strictly forbidden.

    And of course the rules on weapons, what the arena will be like, the rules, etc.

    Also, given that the only restriction for mechs is height with no weight restriction yet, what's forbidding them from making a land dreadnought style 4 legged monstrosity which is below height limit, has automated weapon systems (bypassing the cockpit camera restriction), and can fire in any and all directions at once upon detecting movement? Other than, y'know, sportsmanship.

      Wait, no, I'm stupid and lazy. I went over the rules again in detail.

      Mechs have HP instead of a knockdown/destroy the other to win function a la Battlebots. Also if a mech is stationary for their body length for longer than 20 seconds, they automatically lose hp, counting as destroyed if unmoving for 60 seconds. No campers here! (rule does not apply during active firefights)

      Land Dreadnought fail.

    • One of the reasons that armies don't try building giant robots is that a two story robot like the one in the video clips present a huge target at long ranges. I forget where I heard this, but there's a reason why M1 is low and squat (8 ft tall) where some early tanks like the Sherman were taller (9 ft). But... who cares!
