Mech Engine/Transmissions Question
« on: February 09, 2010, 03:30:41 PM »
Is there anything in literature that hints at whether mechs had transmissions/throttles more like boats or transmission and gears like in cars?  In a boat, for instance, you can go from full reverse to full forward throttle.  In a car you can't do that without doing some damage to your transmission.

I'd say it's more like a jet. most pictures done by artist and models made , also the Battletech cockpit simulators had a throttle on the left, pedals for steering and joystick on the right for aiming.

Fair enough.   I've never flown a jet but from movies I recall that you can move the throttle from full forward to full reverse and while it does take a while for the turbines to change rotation it does so faster than it would if you set the throttle to neutral I imagine?

From MW3: Companion pg. 235:
"8. Primary Throttle
Moving the throttle forward allows for forward running, while backward moves the 'Mech backward if the main rocker switch for reverse movement is activated. The thumb button is used to shift or adjust the throttle, locking it in place when not pressed. If the 'Mech Is equipped with MASC, it will have a second throttle-control thumb switch for engaging the MASC system. When engaged, the computer message relay will display "MASC" until the system is deactivated. Though not included In this design, some BattleMechs mount two joysticks, with the second mounted in the same location as the right-hand stick, but on the left arm of the command couch; the throttle Is moved further back. This arrangement allows a pilot to control half of a BattleMech's arsenal with each stick and permits separate control of arm movements."

Understand that Battlemechs use fusion reactors for power and synthetic muscle 'myomers' for propulsion.

That is, they are likely to be significantly different from any kind of engine or vehicle in use today.

Muscle 'myomers' so its like you trying to go from running to backwards...

Mechs don't really have transmissions like in cars -  the use a structure of muscles much like we humans do... and yes, you can go crazy on the throttles.

Nah, I'm not. I just read a lot of stuff, Is all.

To control a mech with a throttle like that is dubious at best, especially given the level of control over the limbs that is suggested. While in the video games our controls are simplistic and thusly so are our mech movements, in the books, even the game, how exactly does the pilot control kicking actions? Complex stances and movements? It's a little absurd that even in the lore they'd just have 'go forward' and 'go backward' and that's sufficient to move around.

there are pedals, like rudder pedals.
here, just read this, its ripped straight out of the MW3 companion.

it's not super-comprehensive, but it suffices.

All that the throttle levers control is the acceleration and speed level of the mech temphage... For the rest of it, checkout the link in my reply #6 up there... while the ethos of mech cockpits and controls is to streamline and keep things as simple as possible for the pilot, there's a LOT of input that can be done beyond just the "left right up down throttle torso twist."

Greetings all,

Yes I know this thread is old.

As has been stated there is no "transmission" the engine/reactor out puts electrical energy that is shunted to the Myomer/muscles to move the Mech. The Mech is fully capable of guiding itself for basic movement which is controlled through is own computers. The pilots nurohelmet is required for any balance requirements outside the basic movement positions the Mech encounters. As stated the controls of the direction and stance are controlled from the pilots seat, various selections on the sticks, pedals, dash direct different attitudes for the mech. Example the "crouch" movement would only be a selection available while stopped.

There is very little explained on how a pilot and Mech select "pick up" something and actually target the point where the Mech's hands will grab an object. Even reaching out to grab a part of an Enemy mech during combat would be rather difficult if not for the Mech's sensors direction the limbs after the pilot selects that action. Requiring the whole "canon storyline" of mech sensor awareness and some form of basic self awareness. Example: the pilot directs the mech to walk forward in this direction, the mech "see's" or sensors detect the  ground in front of it and places the feet accordingly.

The action of changing direction (forward/reverse) would require the mech's sensors to calculate the load on the legs at this and the next few steps, the angle and rotation of the body, the terrain, and current speed to bring the entire chassis to a full stop. In most cases, turning would be a better option for the pilot depending on speed and terrain. But if keeping your forward armour, well, forward then a stop would be required. Everyone thinks of big metal mech's as slow trundling machines, I would beg to differ. Drive systems (motors/ gears/ hydraulics/ Pneumatics) whatever, are slow - period. This Mech is driven by muscles, which are 300 times faster at reacting than any normal drive system. (considering the weights involved) Only recently, (2013) through new robot designs are scientists finding the speed and strength of the new "nanofiber woven" muscles out preforming "standard" drive elements. This timeline is 3050 and beyond and they have Myomer electrical activated Mech muscles. [Fast, strong, durable, and can be replaced if damaged.] An example of some of the "slower" electrically driven large systems would be the auto industry assembly robots, they zip around with very large weights and most are about 1.5 to 2 tons in mass. Now replace the motors with muscles and you might get a super fast, nearly dangerous assembly arm.

So back on topic, only controls the pilot would make is to select "reverse", the mech should be making all the other calculations. ( and receiving balance feedback from the pilot for the change in inertia)
1. No transmission.
2. reactor only produces power
3. Gyro provides basic stabilization
4. Pilot only "directs" the mech where to move, not how

All for now,
