Roaxis Posted March 30, 2012 Share Posted March 30, 2012 Ok, so I did some reading on the fourms before posting this and uncovered an old thread regarding air gear. This caught my interest because as a part of my Network Administration classes I'm taking Human Hardware Interaction as an elective. As a thought for the project I was thinking about trying to make my own set of Air Gear. Now, I know that someone pointed out the video "rocket skates" on youtube in the post I found. However, to simplify the use of the air gear I was thinking that I would somehow fabricate a sensor pad to detect the pressure of how a person uses the inline skates. As an example I will use the way I skate; when applying pressure to move forward I tend to place more forward pressure. So when programming the pressure pad I will make it so that when (x) amount of preasure is applied in the back it activates a kind of brake system and cuts power to the main motors. To actually power the skates I was thinking about using a motor that had some kind of magnet that could possibly generate excess power to recharge a battery pack containing two LI rechargable batteries. The only other problem that I see is actually taking the time to make the frame for the inlines and finding custom wheels, if I am unable to obtain that I will have to figure that the far back and middle front wheels will be used for braking. The only other issues I see aside from the motors and the power supply would be a shock system to make the ride a little smoother. Link to comment Share on other sites More sharing options...
metal fighter Posted April 10, 2012 Share Posted April 10, 2012 I think that you've got a pretty good grasp on the( air gear idea do you plan to make it compact(challenging making things fit) or are you going for a big bulky design (as the starter before you move on to 'smaller and better'things)I would also like to ask if you've seen the air gear series itself. Also after a bit of research I have found some people who have made some decent air treks using a wireless wrist controller to alternate the speeds you should have a look maybe it'll give you some ideas for improvements to your already good design. Have a look on their site they have even got some test run videos made, here is the link:http://www.etotheipiplusone.net/?page_id=700 I hope I have helped a little with your progress. ps: when you have everything done could you post some pics and videos of them I've always wanted air treks since I saw d anime.

OMG Thats pretty much the exact way I was going to create air treks ! I have blue prints ready, All i'm waiting for is to buy the parts i need...Do you want to help each other out so these so called "air treks" be created? 1 Link to comment Share on other sites More sharing options...
InigoMontoya Posted April 13, 2012 Share Posted April 13, 2012 To actually power the skates I was thinking about using a motor that had some kind of magnet that could possibly generate excess power to recharge a battery pack containing two LI rechargable batteries. If you pull this off, let the Nobel Prize folks know, because you'll be sure to win the prize in Physics. You can't use an electric motor to drive any sort of generator to recharge the batteries that you're using to drive the motor. In the vernacular, that's a "perpetual motion" machine. In geek speak, it's a violation of the 2nd Law of Thermodynamics. Link to comment Share on other sites More sharing options...
lightning diety Posted May 31, 2012 Share Posted May 31, 2012 why not put a small cushion of air between the two layers as a shock system, and when pressing down with your whole foot, channel the air pressure into a tiny turbine so that shifting your weight will slightly increase the out put power, or even use the electrical power generated to recharge the power cells on the roller blades. it is sound in theory, and oddly enough the same principles added by the author of air gear.

MakeItReal Posted June 13, 2012 Share Posted June 13, 2012 there are a few forums dedicated to AT technology(AT haven, AT Project 3...) and blueprints are being improved all the time. its only a matter of time before these become actual things, really. the problem is in getting motors that are compact, powerful, and efficient. seeing as increasing one of these will decrease another naturally, you'll have to find an acceptable balance between power and size. this not considering cost, of course. more expensive motors should perform better, but you can't make it super expensive either. more trade-offs! also, never fall for the "power the skates with tiny wind turbines", or the "generators in the motors" tricks. things like this are cool, but way far out there, and will only inhibit progress. the first rule of engineering is to keep it simple! 2 Link to comment Share on other sites More sharing options...
thesongbird Posted October 27, 2012 Share Posted October 27, 2012 (edited) Hey there guys. I've been working on Air Treks lately with the help of what I found on this forum and I got in contact with the guy from MIT who actually made a pair but I still need a bit of help. If anyone is still actively watching this thread could you PM me or reply please? I'm looking for the AT forums MakeItReal mentioned as well as to bounce a few ideas off people. I got a "break down" of how they worked for the guy in MIT and I'm trying to get some people together to finish them. Roaxis made a comment "However, to simplify the use of the air gear I was thinking that I would somehow fabricate a sensor pad to detect the pressure of how a person uses the inline skates." The way I plan on going with this is, instead of a sensor making a wireless connection to a palm pad like they did in MIT. It requires wireless programming and a sensor pad to a degree. What it does is the harder you squeeze your hand, the faster it makes you go since the sensors tell the motors to turn on and move forward (in a nutshell). Again, that was something designed in MIT that I hope to modify. I'd love to make it foot pressure sensory activated instead of palm so it's more like natural skating, plus it doesn't require wireless programming (which is a jerk to do). But I'd rather make them more like air treks instead of being sort of "remote controlled" I know this post is quite dead and most members are no longer active but I figured I'd give it a shot!

MakeItReal Posted October 27, 2012 Share Posted October 27, 2012 Hello, Songbird! I actually saw you friend me and that is why I'm here XD Apparently I'm not allowed to link to the forums by posting, but if you're interested I think I'm allowed to PM you with a link. However, I must say that it's a little dead these days X| That doesn't stop it from being the epicenter of AT technology though! Link to comment Share on other sites More sharing options...

I'm not leaving until I leave the ground. Charles (the MIT guy) was a great help, now the rest is up to whoever wants involved haha. Seeing the ones he made is just so....inspiring. And with air pressure mods plus proper motor tuning, hopefully they can go further than 3 miles too. Link to comment Share on other sites More sharing options...
Krome X Wong Posted August 7, 2013 Share Posted August 7, 2013 Um dude dont need the pressure pads (I'll approve/specify my answers after your reply to see if ya'all are active till now) I also need your helps so wish you guys still arent loosing hope Link to comment Share on other sites More sharing options...
Shootsfirst Posted September 10, 2013 Share Posted September 10, 2013 I'm Trying to make some ATs and right now I just need a little information on what I need that would be great. If you could help me that would be EVEN BETTER. Just PM me. Plz and thank you. Link to comment Share on other sites More sharing options...
Boneshredder21 Posted September 16, 2013 Share Posted September 16, 2013 Another thing you guys can look into is a game called jet set radio. fun and has same concept of air gear and the magnet thing from what i remember. Link to comment Share on other sites More sharing options...
MrDrewWhite Posted November 26, 2013 Share Posted November 26, 2013 "Air Treks" were created years ago. How do you think they got the idea to make the series? They had to get it from somewhere, and they got it from the REAL THING. They are only 6 years old... So they are relatively new. Since you haven't heard of them, might just mean you don't travel in the right circles. -1 Link to comment Share on other sites More sharing options...

Lightmeow Posted December 4, 2013 Share Posted December 4, 2013 Where? I only find mock-ups, CAD drawings and cartoons. I could give you a way to make them, but it involves strapping a chain saw engine to the back of one skate, but it works. I am working on a way to make them work on both blades. Anyone have any suggestions on a smaller motor I could use for mine, because the chain saw engine gives you a little to much torque. Here is two links of what it looks like: www.youtube.com/watch?v=bid8z7-XvTUwww.youtube.com/watch?v=50b_DKRothM Link to comment Share on other sites More sharing options...
decraig Posted December 7, 2013 Share Posted December 7, 2013 (edited) Lightmeow, what do you mean by the torque is to high? Is it jumpy; rapid velocity changes? ---------------------------------------------------------------------------------------- I did a bit of research on electric power skate boards ~5 years ago. For best power density at low torque, which is what you need, the Axi Outrunner series motors were nearly the highest at that time. They are used on model airplanes. Anything much better, in electric, is probably fantasy. Highest usable power density batteries available are Lithium polymer, as far as I know. So how do you get the required power density crammed into some footware so you can zoom around? I don't know. But, all and all, electric power has nowhere near as much power density as nitromethane used in a two stroke engine. But the torque range is narrow. The technological challenge would be the transmission. Edited December 7, 2013 by decraig Link to comment Share on other sites More sharing options...

decraig Posted December 10, 2013 Share Posted December 10, 2013 Ok. It sounds a bit award to accelerate. Do lead with the powered or unpowered skate? Link to comment Share on other sites More sharing options...

Kbo39 Posted January 12, 2014 Share Posted January 12, 2014 Ok I know that this is some what old to post one but I have an idea, I don't know if it would work. What I was thinking could you power an electric motor/engine, with a negative ion generator. I don't know much about electricity, but what I do know is basic but I just thought that this might work for a was to power something. This is just my input but I don't know if it would work.

bladeRoller Posted January 14, 2014 Share Posted January 14, 2014 How are things going with this? any ideas working? Being tested? Being drawn? Thought of? Well, I've thought of one. Backpacks, or any other body strap that could hold large battery cells. a side pouch, satchel, fanny pack, leg strap, anything. this would definitely improve the skate's abillity to go for long distances, and would be good for prototypes or even a starting project. then, once that became popular, companies may invest into researching making the cells fit within the skate, as well as stronger, smaller motors for them.

Lightmeow Posted January 14, 2014 Share Posted January 14, 2014 If someone wants some speed, a good idea is to not screw around with the normal electric motors. Get some brush less motors, and hock up a 12 volt car battery. The more voltage you can pump through the brush less motors, the better. If you have money, buy brush less motors with 98% efficiency. Then some how make a variable resistor, or if you got a RC car electric speed controller, it could be wire less, and take apart a RC remote, then take out the servo, make the remote hand held(for just one motor, you just need 1 servo, a normal RC car remote has 4 servos). Also, you could have the battery in a backpack. These brush less motors are awesome, if you get a good one, you could get up to 110mph!!!(But it is very expensive) Regards Link to comment Share on other sites More sharing options...
i am a God Posted August 9, 2014 Share Posted August 9, 2014 But i think people don't wanna carry a car battery in a back pack but that's just me Link to comment Share on other sites More sharing options...
