Lo and behold, it looks like I've returned to smash peoples dreams on another robotics topic.
Sorry if anything I say here depresses anyone.
First, I'll talk about this guy selling "mechs".
While he's welded together a rather neat looking piece of art, that's about as far as he's going to get with it. (But as art it might still fetch
the price he's asking... I've seen weirder artworks go for allot more).
For one, he hasn't worked on balance, weight distribution, interface... the list is endless. I'm not saying it's impossible, I'm saying he hasn't
done the necessary work. He started with the frame and body kit, skipping just about everything else that matters.
(Not to mention it's decaying faster than he can build it out there, lol.)
However, to stroke his ego, he seems to be a fine welder. If I were doing a "mech" project (which I likely wouldn't, there's enough of a headache
in tracked and wheeled robots, let alone bipedal ones), if I were I'd look for someone like him for the structural assembly.
He's got welding talent alright, and an open mind... but he seems lost on the actual 'functionality" department. If he were working on a team, he
wouldn't have to worry about everything else, he could be perfectly happy just welding away.
Second topic, someone also posted the "land walker". Imagine how depressed I was when I watched the video of it years ago. It's not actually a
Here's how that land walker works.
Under both feet you will find wheels... or rather, as he put it, big bearings on suspension.
It's not lifting the foot off the ground, it's alleviating pressure off the wheels enough that it can roll on them. It then rolls that foot forward,
and re-plants pressure on it, the wheels are pushed back under the foot via compressing the suspension.
The foot never leaves the ground.
Think of it like a child learning to roller skate. They never pick their feet up, they try to shimmy along instead. (The analogy works best if you are
old enough to remember those Playschool one way roller skates.)
Another way of thinking of it would be to take two cars, and stick a robot looking carnival float on top of them. Drive one car forward, stop. Drive
the other car forward, stop. Keep repeating. It'll look like the robot float is semi walking. Where in fact, it's just two cars taking turns driving
But... as I mentioned about the previous guys "mech", it's still really interesting to look at, and could be considered high priced art.
Bi-pedal robotic systems are still just in the realm of small toys, and human sized robots.
Is it impossible to build a mech? Absolutely NOT!
But these two approaches, while imaginative, are (for one of them) not capable of balancing or walking at all, and (for the other) simply not an
actual walking robot.
I've tried to simplify this post as much as I can. So if something I said doesn't make sense, let me know and I'll try to explain it again.
Now for the not so depressing part!
I figured after all that depressing talk, I might remind you of walking machines that actually do work.
Introducing the TIMBERJACK!
A 6 legged walking machine designed to perform logging operations without the need to clear-cut roads to the tree removal site!
Comes complete with an arm and gripper.
We all know it and love it...
the BIG DOG!
Kick it, abuse it, load it down with 250lbs of cargo, and kick it some more! It just keeps standing and waiting for another beating!
Now these guys were just playing WAY too much Halflife 2.
You've already seen it, but here it is again.
There are literally hundreds of walking robot projects that do work... so don't get depressed.
But I think it will be a at least another decade before you can strap yourself into a large exoskeleton and post a youtube video of your favorite one
liner "get away from her you ..."
Don't worry though, it's coming.
