Nauti-Craft Marine Suspension Technology

SFOGuy says...

Not just throwing rocks, but---what is the practical application of this? As a pleasure craft, maintaining all those extra hydraulics would drive maintenance expenses through the roof from the perspective of a recreational boater.
I'm also concerned about reliability, elevation of center of gravity, response to being sideways in a seaway... the second half with the outrigger "sled' maybe would have application in military stuff? Air/Sea rescue?

So there's this construction site...

transmorpher says...

Idiots, the thief and the construction workers.

-Jumping onto of a moving vehicle
-Punching the windscreen(not possible to break with your hand).
-Holding on the car as it continues to gain serious speed
-RAMMING SAID VEHICLE (causing $$$$ damage to your own car)while your colleague is still hanging onto the front.

For what? a $200 bit of machinery? Not even worth the damage you'd do to your hand from punching the windscreen (considering you're a construction worker and your income relies on working hands!) let alone the potential brain damage, disability or death if you come off the bonnet.

I'm also not sure how the law would interpret ramming a car off the road, or flipping it, or squishing it against other cars and causing more collateral than the tool is worth (which you'd have to do to make it stop), just to stop a petty thief. And honestly if you damaged my car to stop a thief, you'd be paying for my car.

Do these people think they are living in an action movie? I know the Terminator jumped onto a car and punched through the windscreen, but they used a hydraulic ram and hid it with special fx.

Idiots.

Would love to see how this ends though cause I'd be very surprised if everything /everyone was fine.

Introducing Handle - new research robot from Boston Dynamics

newtboy jokingly says...

I would like to ask you to think twice before signing up to be a test subject to help in developing robotic hand jobs. Wait until they have it perfected......unless you LIKE industrial hydraulic press and shear level forces applied to your penis, then do whatever floats your boat (but don't whine to me about your flat, mangled, or missing peen...I warned you).

Misread the title initially, thought it said Handie, new research robot, was like "How does one sign up as a research subject?!"

Crushing Adamantium with Hydraulic Press

Lake Oroville dam spillway damage

SFOGuy says...

For reference: flows at the their highest out of the spillways were exceeding the flows at Niagra Falls---

And---in 2005, 3 environmental groups tried to get the State to concrete armor the emergency spillway---they protested it would be too expensive and not necessary...And of course, with the main spillway out of action, the emergency spillway has started to erode as well---and 200,000 people have been evacuated. To my understanding---and I'm not a hydraulic engineer---the risk with the emergency spillway is that the water flowing over the concrete "cap" or "curb" has started to...duh...erode the earth below the cap. If it erodes too far, the concrete cap will tumble off, a 30 foot wall of water will cascade over the edge, the the dam will start to erode...

The Bose Suspension In Action

Payback says...

The first thing you need to understand is the suspension doesn't use springs or shock absorbers. The whole thing is linear electric motors on each control arm. (Great huge solenoids) The suspension moves up and down independent of weight or inertia. It works fast enough that it starts to compensate for bumps BEFORE the tires hit the bump.

This system has more in common with a 1965 Impala with hydraulic rams bouncing in a parking lot than a conventional car suspension.

For the most part, it scans the road ahead.
See a dip down? Extend the wheel.
See a bump up? Retract the wheel.

I'm fairly certain the ollie was manually instigated by the driver.
Much like hitting the turbo boost on K.I.T.T. it's just a button and the computer does the jump.

Press button:
Retract the wheels, starting with the front. (to maximize suspension travel)
Push down hard on front, then rear wheels. (Launch car up)
Retract front then rear wheels. (tuck the wheels up)
*car passes over 2x4*
Push down on front, then rear wheels.(ready for touchdown)
*tires hit pavement*
Retract front, then rear, wheels slowly to absorb impact.

I'm very confused by that bit. Was that bunny hop activated by the driver (how?) or autonomous (and again, how)?

If you had a fear of elevators before...

Payback says...

That's why I'd prefer to live in a walk up or a building short enough to be serviced by a hydraulic elevator. The ones on top of a long hydraulic ram like on a backhoe. They can fail, but all that happens is you slowly sink into the basement.

Dag might not like that though...

WaterDweller said:

May not be common knowledge, but elevators actually have a counterweight, that weighs as much as the elevator would when it's filled by a certain number of people, to ease the load on the motor. When there's only one person in the elevator, the motor actually has to work harder when the elevator is on the way down than on the way up, as it has to lift the counterweight.
