The Walking Beast by Moltensteelman is a 14,250 pound real life walking mech that carries a driver and passenger in the cockpit while seven passengers enjoy an unforgettable ride on the top deck.
Some of our Swedish buses need some tender loving care. When the bus goes over a speed bump, the back end come down so hard it feels as if you back is gonna break.
I saw that thing at Burning Man back in the day. It was rather slow and heavy, and caused a minor earthquake every time it took a step, but it did walk.
Would love to see a bipedal version. Maybe with a rail gun attached that fires a nuclear warhead? Dinosaur-like noises would also be pretty cool whenever the mouth opens.
IntoTheVoid13 Wow, you know what, that's not a bad name for it all. Since we're brainstorming here, let's just add in a gatling gun, some anti-tank missiles, and maybe an electric laser beam too. You know, for security purposes... (This is how ridiculous I imagine it was when Otacon must have brought up the idea for this stuff)
+Lyrical Zoot Yeah! No one should have an opinion about anything that they haven't made themselves! And only those who have been a US president in the past are allowed to criticizes anything Trump does!
I had a "moon explorer" walking toy that looked just like this when i was a kid. I used to set it going in the backyard and just watch it walk all over the place.
Would the wheels be turning while the legs are moving similar to skating? or would they be a separate system, one for rolling and one for walking? Wheels on flat ground will be more efficient.
I'm extremely interested in this project, and would like to know how exactly the head raises and lowers. This type of stuff just makes me wonder where the feild of engineering will go.
The head raises and lowers with a hydraulic cylinder, the hydraulic circuits have flow control valves to keep the cylinders at a controlled speed. There is also a mechanical latching mechanism as a safety in case the hydraulics fail.
The rotating/moving mass of the machine is about 43% of it's total weight and moving in an unbalanced triangular motion, if we move the parts to quickly it would tear itself apart. The motor and gearing is more then capable of moving the machine a lot faster. Mechs that operate on hydraulics have multiple cylinders per leg, typically 3 or 4 x the number of legs 6 or 8. with 18 to 32 cylinders to fill with fluid simultaneously. The size of the pump and cooling system would be a limiting factor.
This is quite an accomplishment. It reminds me of the work done by Theo Jansen. You might take a look at Theo's design, because his walking produces no wavy up and down motion. It is very linear and smooth, almost like it is on wheels. Turning seems to be the biggest challenge, and you have a sort of method to do that, but it is not optimal, is it? When you're moving on legs, one way to do it is to separate the mechanism for the front and rear, then use hydraulic rams to bend the body.
The hydraulic lift speed is controlled by flow control valves. If the valves were set to move to quickly it would make it difficult to balance the machine and with the weight of the machine, lowering it back to the ground or off the trailer at a higher speed would be dangerous.The drawback is that when raising and lowering the arm when it is not in contact with the ground is also slow do to the restriction in the line. Bypass valves could be added to speed things up, but I'm lacking funding.
that's a heck of a jolt with each step. I could do it if there were a really nice, thick air mattress to lie on. Have you looked at Theo Jansen's Strandbeest walking mechanism? It's open source and no jolt whatsoever. Completely smooth. Doesn't even change altitude as it strides. Pretty great.
You might want to consider the smoother walking mechanism of the Strandbeast by Theo Jansen. They're also a lot lighter, so their ideas may not work for you, but they're probably worth considering.
correct, lighter frame and lighter moving parts would allow for a higher speed to a point, a statically balanced machine has a limit to how fast it can move and still keep the center of gravity within it's gate. A dynamically ballanced machine would be better for higher speeds.
Where are hydraulic arms gonna go and wagon bins for caring materials; can use it for Industrial mining or sentry duty? Please explain the purpose of this invention. Thanks.
Another question! o: What if the mech were to use a different form of transportation than walking - like use of wheels on its feet? As well as the mech being a quadruped to increase stability - would that then make it more efficient for speed while keeping balance?
Sorry, the new RU-vid layout was difficult for me - couldn't find my inbox for two weeks! And yes, much similar, but I was thinking maybe to keep the legs stationary to avoid consuming more energy. You are correct - I imagined a machine that would walk and roll (ha!), in the event it would have to traverse steep grades.
It just looks like the sort of thing that someone who lived in a desert 500 miles from anyone else would use to travel in. If it was somehow powered by wind and solar it could be a cool steampunk style machine.
Why would anyone want to use this thing to travel in? You would walk faster than this. It is heavy, slow, cant turn and more expensive than a used car.
One question, why does it take so long for the hydraulic lift to adjust and set itself on the ground? Same applies for the legs. Sorry if it's a novice question - been getting into studying machines and I noticed all mechs similar to yours have slow moving joints. O:
great job but what if we used like, 4 wheels. I know it sounds crazy but think about it! We could like wrap the wheels in some kind of rubber to make it smoother and then maybe it won't need to be turned by a small person on a stand but rather by turning some sort of other 5th wheel that's inside the thing to operate the steering? just a thought
