Why cant i build a 30 foot Hammerstein robot

Hi I'd like to build an ABC warrior.

I spend the year building a CNC plasma cutter, its not finished, and then I bought a CNC router to repair. I'll put a pic below the arm.

So I joined loads of facebook CNC groups and somewhere in there, someone posted a KUKA robot arm they had just taken delivery of. That threw me, I didnt realise they were possible to own. But of course, they are old tech by now, so it makes sense.

Anyway, I looked at the vids, and at the servos mechanisms they use, they are not the same as the servos and steppers on my machines, But at the end of the day, they are just motors, and understandable. 

Cut a long story short, I want to build a 30 foot high bipedal robot for bashing other robots. I dont care if it takes me 5 years and all my cash,  I will destroy it if I can find an opponent.   

Why cant i do this, I'm sure there are a lot of reasons, what does the list look like?

Is it possible at all?

$4000. There is enough there to make a leg or an arm, no? so maybe 30 K for a full robot? would take me several years to pay for.

Take a look at the following article to get an idea of what might be involved:

http://www.scmp.com/news/asia/east-asia/article/2057474/avatar-style-s-korean-manned-robot-takes-first-baby-steps

Note "Yang, who dreamed as a child of building his own robot, said he has invested 242 billion won (US$200 million) in the project since 2014 to “bring to life what only seemed possible in movies and cartoons”.

The project is three years old and he has a team of engineers involved. The end result is still far from finished and as you can imagine, they are very, very far from even considering losing their investment in a fight.

The Kuka arm is not meant to support its own weight, so the overall weight of the arm is of little consequence since it’s not meant to be mobile. For a mobile robot, everything needs to be lightweight yet very powerful (hence, very expensive). If you’re really interested in a robot for battle, consider:

https://www.theverge.com/2017/10/12/16464150/megabots-giant-robot-duel-live-stream-watch-twitch

Notice how neither robot really has “legs” - the USA team us using tracks, while the Japanese team is using wheels. You can imagine that given the investment in each robot, neither team really wants to see any damage.

Robots which are used for actual combat are expensive enough with just tracks and wheels, and adding arms for close-quarters combat is rarely used given the use of ballistics, rockets and missiles. A standard rocket launcher (let alone a tank) would likely take down either robot within seconds, meaning the arms and legs would not serve any function.

This is not to say that humanoid and mech type robots are not amazingly cool.

 

 

i dont know why you would

i dont know why you would want to put rockets on what effectively a demolition derby robot. It totally finishes to contest in seconds.

I personally would like to see robots batter each other steel on steel, much like the current robot wars, but scaled up. same implements.

guns and rockets make it not fun anymore. 


Going to read the articles you linked to, cheers, i saw that method 2, its very impressive. 

Im not thinking about software. That is beyond me. But we are due a robot O/S soon anyway, so i could build a frame and wait. 

I might start with just legs.

You might find inspiration and some learnings. 

But that’s quite a project you’re starting. I’m curious about what you’re going to achieve :)
