How are frames controlled?

Postby Wadmaasi » Thu Apr 19, 2012 1:13 pm

In the Solar Century setting, of course. Macross-style joysticks and pedals? Cybernetic direct neural links? Some sort of pseudo-pneumatic system like Ripley's loader? HOW?!

InB4 peach joke. :D

Good question. I could need that info for further writing. So far, I am presuming that there are some sort of controls that are not via direct neural links, but maybe somewhat akin to the in Matrix. Neural Links raise all kinds of problems (ADHD Pilots wouldn't work... :D). Also, our 'Frames are what, 4 - 5 metres (12 - 15ft) tall? Having complex neural links would appear to be somewhat over the top. At that size, you don't really need an intricate gyroscope to stay steady. But maybe I am missing something.

Fun question! I'll answer even though I really have a staggering ton of &%$# to do!

There are two parts.

First, there are the pilot's controls — levers and pedals in some cases, responsive exoskeletons in others. The Chub and Hi-Leg use limbs and pedals and are generally piloted like an airplane. I'd have to check with Soren, but I think the Commissar is worn like clothing. Exhausting, bulky clothing, like the power loader, yeah. The Ijad have the ability to use different body forms, so the Scramblers follow the movement of a critter called a "ghanat" that's tied into the system. It's sorta like a mammalian tarantula with a body maybe 40 cm in diameter. They have little fingers that they use for grooming and climbing in nature, but Ijad use those fingers as a broad control scheme. Any creature with a central nervous system works fine for them, which is why there are so many shapes.

Then there's the other part: muscle cylinder fluid isn't just a compressible fluid. Sure, when you run electricity through it, it reduces in volume, and does so linearly, like filings along a magnetic field. But also, cylinders are interconnected, which means that they also act as a nervous system, generating an electrical current that is then sent to other cylinders. That means that you "train" limbs to move according to the gestures of the pilot. More experienced pilots know a series of exercises that get a new frame's cylinders working in tight unison — it's a lot like shadow boxing or other martial art forms. Eventually, those actions become reflexes, keeping the frame upright, ducking gracefully, rolling, or even blocking or punching.

When getting into another pilot's frame, it's like putting on someone else's leather shoes: pinchy in some spots, loose in others. When getting into a new one, it's like trying to build something from LEGO® while wearing boxing gloves.

Answers! I'm currently just taking a break from wedding planning, but next week I edit: would like to sit down and explicate this further with pretty pictures. edit: boy, that didn't happen like whoa.

Purpose-built combat models (Chubs, Rumble Monkeys, Hi-Legs, and Striders) use a systems of sticks, switches, and pedals linked to programmable, contextual movement and behavior macros filtered by a rudimentary AI. The advantages of this approach are speed, flexibility and endurance - you can operate a frame for days on end like this, without wearing yourself down, carry out actions instantly, and operate a wide variety of body plans. The disadvantages are lack of precision and a steep learning curve.

Civilian models, and military models derived from civilian models (Conscripts and Commissars, and the standard-model Scrambler), use various degrees of body emulation. On most worker models, you have this big arm-and-torso frame with pedals for the legs. A lot of older Free Colonial soldiers, like Haski, are fantastically ripped because they've been operating these things for so long, and they take pretty minimal training to use precisely and effectively. But they wear even veteran users down a lot faster, and can lead to some idiosyncratic joint damage down the line.

Both approaches assume you've got a helmet that feeds sensor data directly to your eyes and ears - tracking your eye movements and aligning visual and auditory sensors to match. It's a lot of data to process at once, and Frame-riders with PTSD develop a very distinct and noticeable pattern of uncontrolled face- and neck-twitches. And they both need to be exercised to sync everything up.

Nobody has managed to build a working neural interface yet. The Ijad are probably the closest to a working model, but everyone is experimenting, because the potential advantage is enormous.

The suppressed wannabe-author in me is all agiggles that you guys have thought this much (and likely more!) about it. I really like that there isn't a single method of control.

Admission: we have principles — some stated, some unspoken — that we've developed over the last year or so. When we need a specific fact, we apply the principles and out pops a fact!

Our techniques are actually abstracted from two of my other games, and . Plus, of course, Soren and I like the same science fiction, so we can shorthand a lot of the references.

The storage happens in the muscle-fluid cylinders, so ... that won't work, sadly.

AI is pretty wussy in this setting, but it would certainly help bring a frame up to speed with a new pilot faster, synching up the frame's cylinders before the pilot even starts training.

But it's rudimentary. It's more like a hindbrain or even chordal response system than a decision-making system.

Well, there are different ways to do it, too, but imagine a fistful of little buttons and sub-joysticks that give you a lot of fine control. As you repeat motions and give them finesse, you get the motions working together.

Simpler frames mimic the pilot's body movements, too, of course. But they're only capable of human motions, not, say, flying. So there's a balance that frame designers find between the assumed skill of the pilot and the non-humanness of the mission.

In an ST-07, the controls are this kind of thing.

...plus some multi-axis pedals and a helmet that points the sensors around.

Check the chorded key commands starting at 1:43 - it's a similar concept.
