Hmmm... I didn't know that you all are starting to make ATs. There's a problem in making these ATs. The main problem is finding materials that are strong and light-weight... for instance, fibre-carbon is widely used in F1 parts because it's light and strong. I managed to make up some research in the net... I managed to find the suitable pressure metre which is small and light but expensive. However, it can be programed to translate readings for instance, applying that amount of presure that is more than the limit (can be set) will cause it to move. However about going backwards and forward motion can be done by using two different sensory points of the contact point between your soe to the pressure detector (flat and thin). The fuel however... I would recommand using non reactive and easy to find source. Helium (liquid) might do. But when I went to a 'Tamiya' shop (sells miniture motors for small racing cars), I happened to find the engine that is powerful enough to generate that AT plus it uses a fuel - gasoline or nitro. But however, it's not tested practically but theoractically... I'm not to sure. Designs made may not be like an AT but there's a room to the possibilities.
PS: in Air Gear manga, they once shown how At was made... ridiculusly or not... they included a driver (probably to read and calibrate presure) and batteries (Probably a lithium ion based type which can be rechargable and powerful compared to your alkaline based batteries).
with today tech i think it is still very hard to make an AT
especially cheap ones so you can buy it at nearest shop
maybe in the future we can see this AT in real
many cool gadget comes from nasty idea like AT
maybe some day....
Smile is a deadly weapon
you are talking about how hard it is to creat a good and cheap AT but you forget that AT in AG are not cheap at all, they are very expensive because that they ARE made from a strong and light material which is, sadly, quite expensive as well.
There is also the battery subject, again, it's expensive, a rechargeable battery that can last for a long time and provide much power(even enough to go upside a wall) is made from chemicals that can store much energy in a rather small size(if you look back to when we could see those batteries you will see that they are big, fat and probebly not light weighted[i think that they are the heaviest thing in the AT]).
AT weight about as much as normal roller blades only that they are motored,faster and much, MUCH more expensive.
Controls are rather simple and I think they were covered in the manga. I believe the controls were set in the toes of the shoes. Accelerator on the bottom, and break on the top. Accelerator was pressure sensitive, just like a PS2 controller buttons. The hard you push the fast it goes. This means that you get max force when kicking off or jumping and no rotation when the foot is at rest in mid air or coasting, which saves battery life.
Besides what are you going to be doing when you press down on the accelerator with any real amount of force? kicking off for speed like inline skates, jumping, leaning forward to go faster. since these are the main thing one would be doing for acceleration it'd be rather easy to set the sensitivity of the acceleration button. lighter people weigh less thus hit the accelerator lighter than heavy people, but conversely it takes less torque to move a light person any way and starting all torque is all that matters. Later about torque.
If we are going with brushless motors for the ATs it is possible to use them as breaks if you have a circuit board. To do this all one does is design the break button to lock the motor in one polarity via the board, thus causing a breaking action. This isn't possible with a traditional brush motor.
Speaking of which electric motors already achieve high speeds. Hard drive motors do 7 to 15k rpms. On the lowest end 7000 RPMs on a 3 inch diameter wheel is 62.44~ mph
Factoid: there is 63360 inches in a mile.
math for the interested:
circumference times rotation, translate from inches to miles, then minute to an hour
lithium-ion batteries are the "current" way to go atm seeing as they are used to power laptops for on average 5 hours at a time and are lighter weight than other batteries. AT battles don't last half as long if people have noticed.
The only real problems are size of the battery(unless you don't mind platform shoes) and torque for acceleration.
I can see getting 3 cell phone sized batteries in heel area, but that's about it.
Torque and only really be solved a combination of ways.
1. a gear box in the wheel. instead of the outside of the motor being the wheel have it get xfer is power to the gears for a 3:1 or a 2:1 ratio for example.
2. Super magnets in the motor. Stronger the magnet the stronger the torque.
3. have the electronics board have a transformer to boost power to the motors for stronger electro magnets.
gear box ex.
1: gear on a non magnetic plate from the motor.
2:gear to the wheel
4:diameter of the plate that is connected to the motor to the middle gear which is on the inside.
It's true that it can be expensive to make a decent AT (Fibre- carbon, pressure pads and lithium ion based batteries) but it proves that we can make one.
I might suggest using brake pads instead of brush brakes if you want to make it light. Remember, it's all about light weight or it'll be as heavy as a tank. No, I don't expect it to make us fly into the sky like Ikki do but it would be great if it does.
At the first book, I found something rather unreal. For instance, Ikki's AT being charged up using the electric cable by the motor. Such charge can cause and overwhelming discharge which might lead to circuit burns and explotions of the batteries.
Semi-conductors and capasitors is a must since we were told that AT can be charged (Spitfire was seen charging up his AT) Wheels... hmmm... how about using ordinary rollerskates wheels. It's easy to find plus it's cheep.
correct me if I'm wrong...but in the beginning, when ikki held AT for the first time, didn't he say it was light as a feather? I remember from my roller blades that it is HEAVY.

oh, and in airgear, the ATs are customizable, so that's another problem to work on since if a clueless person does something to his/her AT the wheel might explode or something 0_o
srsly i think that if we use it like a two wheel drive and the back wheels are the only ones powering we can use the front wheel as a generator sort of thing...srsly with that amount of revs even a small generator could make a decent amount to keep the battery life up for about another 3-4 hours or channeling that energy to some kind of intercooling....for the suspensions you could have the ^ shape with a straight -- spring joining the two wheels that are on limiter hinges which creates high jumping/push/landing capabilities....the springs would probably be replaced every half a year but it's worth it... so that would help with your initial "run" to "charge up" the AT, with the intercooling system, "flying" problem and suspenion.....i guess this might help......but i could be of lesser knowledge so yeah.... anyways i also thought that we could use a splatter shield and grinding case so we can perform awesome grinds and stop the wetness from entering inside the AT.... i love airgear!!!!!

well you can try using the motors from the mini 4WD that tamiya makes and try putting that on the axel of your rollerblade wheels.
if you got a frame for rollerskates thats much better. you cant actually control it though.
i dont think leaning won't help if your using an actual a-t. the force from the wheel should be enough to make you flip over regardless
