LEGO Robot Wars / BattleBots

PaperballparkPaperballpark Near ManchesterMember Posts: 4,048
I'm slightly surprised there's no topic for this already, so I thought I'd create one.

To start us off, here's the highlights from the 'LEGO Robot Wars' held at The Great Western Brick Show in Swindon, UK, last weekend:



The rules we follow are:

Robot rules:
- must weigh no more than 1kg
- must fit inside a 32 stud cube (approx 25cm)
- must use genuine unmodified LEGO parts

Fight rules:
- last a maximum of 2 minutes
- ends when a robot is immobilised, goes down the pit or goes out of the arena
- if there's no clear winner after 2 mins, the winner is decided by audience vote

    Here is at least one battle from Brickcon 2019 this past weekend. I was able to watch a few rounds.

    fun stuff. But so many just seem to drive themselves right into the pit.

    This is absolutely fantastic!  Lots of unorthodox designs, and they seem to be doing pretty well overall, which is great!  The pit is what makes it really great I think, because it allows for some of the not explicitly 'destruction' themed bots to perform better than they might have otherwise, and allows for some spectacular self owns :P

    I could definitely see this being just as much of a highlight to a show as the GBC loops have become.  I think they compliment each other really well, actually, and I could probably go to a show and watch one or the other all day and never get bored!

    It's the fourth year of running it, and the arena has developed a pronounced ridge on this side of the pit, and also has a bit of a dip to the 'top' of the pit. These account for some of the stranger ones where they seem to turn towards the pit and drop in. There'll likely be a new arena for next year.

    As for the others, the Power Functions IR system isn't amazing in a wide open space like that, and the signal can sometimes fluctuate, giving less control over the robots. Maybe the Powered Up system will work better, although it's more expensive. Someone tried s-bricks at a different show a few years back, but found that the system got overwhelmed with the amount of devices in range when the public were there. They switched to IR!

    yeah the challenge seems to be more about controlling your robot correctly than fighting the other ones.

    Thanks for sharing these. We are just rewatching Robot Wars on DVD and missing the BBC programme, this is great fun too. Some very cool designs.

    Really enjoyed that, though I think the pit won this tournament :)

    They look great fun, although the driving does seem rather lacking in skills. Was the sheep like thing there just to get beaten up, or does it have some defenses?


    Although nothing beats Robot Wars as done in Phoenix Nights.

    That was surprisingly enjoyable to watch.

    Ah, I skipped over the first section and didn't realise they were named!

    "Sacrificial lamb" was spot on as it was designed to crumble following minimal provocation!

    Yeah I realised that this year there would be a lack of robots built to have bits bashed off them, and that what we needed was a sacrificial lamb, so to speak. So 4 days before the show, I built Sacrificial Lamb! It did its job admirably. There's a timelapse on the Brickish Facebook page of a half-hour rebuild of it.

    What you don't see in the video (but which was demonstrated to the audience before each battle it was in) is how the battery box inside it is switched on... ;)

    ^ Let's just say that the announcer didn't explain to the kids how it was done :-)

    I thought I'd revive this topic :)

    For those interested, I'm in the process of building my first proper new robot since 2019, and this morning I managed to measure how fast the weapon spins.

    Using two separate methods, I was able to determine that it spins at about 2400rpm. That's 40 times per second...

    No pictures yet as it's not finished, but I'll post some once it is.

    I suspect a lot of robots will be immobilised well before that...!

    Meet Dr Smash. Dr 'Monster' Smash. Weighing about 830g and with a weapon which spins at 2200rpm - 37 times per second.

    What does the weapon do? It looks a bit too cute to be a monster.
  • PaperballparkPaperballpark Near ManchesterMember Posts: 4,048
    It's a bar spinner which spins really fast :)
  • CCCCCC UKMember Posts: 19,645
    Does it do damage to other robots ? Especially where there are plates on it, are they equally likely to fly off compared to bits on the other robot? 

    Do you have a picture underneath. Presumably there is a dolly wheel or something.

    That's going to cause some pain. I haven't shown this to Mr Crab yet...

    I've occasionaly watched some battles and I was under the impression that what made the most difference was the weight rather than the weapons. You can have a bot with extremly destructive weapons that will do particularly well, but often the heavy, dense ones seem hard to beat. I kinda remember one was just a big moving slope, you drove it under other bots and it flipped them.

    Roadblock! 

    One of the great things about Robot Wars was the evolution in design. What was successful in one series became less useful with time, as designers invented ways to overcome the advantages. Self righting mechanisms overcome being flipped over.

    Yes, I tested it against my 'White Knight' robot and it flipped it over with ease, then bashed some side panels off it. The plates on the back of this robot are for decoration only, and it doesn't matter if they come off :)

    The underneath is almost exactly the same as the top, except the 'eyes' are plain Teal balls. It's made to run both ways up, so that flipping it has no effect.

    You haven't seen the weapon spinning yet! It's quite something. It also makes a high-pitched whirring sound as it spins up :)

    Yes, Lego Robot Wars has seen the same kind of evolution. The best robot from when we started in 2016 can't hold a candle to the newer robots from 2019/20.

    We have a weight limit of 1kg, which is very good as it makes it very difficult to build a sturdy robot with a powerful weapon. There's usually a trade-off needed somewhere to get it under the weight limit, which then gives each robot different weaknesses.

    The evolution of the machines was definitely one of the best reasons to keep watching.  Especially interesting was watching how the different rules and external threats of each show drove the evolution of machines in different ways.  I understand how it could be hard to keep one of these series running for a prolonged period, but man it would be really awesome to see how things would have change over the course of like 20 or 30 years, as both bots and technology evolved.

    I just realized it is Dr written in plates.
