Tronic's Full motion car racing simulator using x-sim

Congrats :clap:

And as far as I see, you have converted your joyrider to AMC1.5 control finally.

How was the feedback? Did the car batteries last long enough?

Yes, I was preparing it for some time now but didn't had the chance to finish it at home. As you know, the Greeks, are known for doing miracles on the last minute... It was actually completed on site on the Athens Digital Week area!!!! :lol:















I have charged the battery only once before the event and lasted playing all day for the four days that it was available to the public to try it. I can calculate that more than 100 people tried it!!!

As you can see on the video that the Amp meter is shown, the motors have little consumption and only peaks of 20amp when the two of them are moving together!

I also took there some of my robots that can be seen on the next photo. Its the flower, the six-legged bug and the tank robot, posing in front of the robot soccer team:

About the position feedback...

I have decided to use Magnetic hall effect sensors: SS495 Ratiometric Linear Solid State sensors

http://content.honeywell.com/sensing/pr ... c20020.pdf

I have placed in the joints of the frames exactly like I was doing with the potentiometers, and placed some pieces of neodymium magnets from old PC hard drives facing them. Its a cool way to measure -45 to +45 degrees and very immune to noise!!!! Their resolution is about 12-bit.







Another thing that did for first time was to enhance the safety. Thats why I used a control panel that I could watch Voltage and Ampere status of the battery and added Power Line Cutoff switch for the motors. Another measure was that I used a key operated switch to power the AMC, with detachable key, in case some kid was messing with the buttons and got it power it on by accident while I was away for lunch!







And of course added 10amp fuses that could save the mosfets in case someone was lying about his weight. :brows: I was authorize people that weight from 65~85 Kg on it with minor adjustments on the seat (yeah it has rails!) to balance properly their weight!



In overall I was happy that it was gone well without any failures, especially when I was live on TV !!!!! :yippiee:


Now I feel a bit sad that it was ended and too tired to put it together back at home!!! I had to almost unscrew it to pieces to get it fit in my car!!!

Looks like fun. Wow, how long did it for you to assemble and disassemble it at the show? Awesome job as usual. :thbup:

Let me count...

2.5 hours disassembling at home,
30 min to load it to car (I live in third floor)...

1 hour of driving to the Athens Digital Week event area.

15 min to unload it from car (I had some help there).

2 hours to assemble all mechanical parts together.

Another 1 hour to attach the electrical and electronics part (I had to double - triple check everything)

And about 2 hours of calibration of the position sensors and the AMC firmware. I had to limit the motion to -30, +30 degrees on both axis cause I felt a little responsible for the safety of the test drivers visitors :lol:

9.5 hours total... And this is only for getting it to the event....


Thanos

You should add the hall sensors feature to the AMC thread :clap:

Yesterday, I received my price from the sponsor of the Robotics section of the Athens Digital Week...




Regards, Thanos

Just to say congratulation Thanos Well deserved Prize,and the 1st of many for the future :thbup:

Hi,

Here is some more video, I dig up from my camera, from the Athens Digital Week show...

-I had to disable the pitch axis when I let my friend's kids test drive it because of the huge unbalance...!! It worked well in bank motion only for the little fella though!!



Regards, Thanos

No, its still in that corner... Its really heartbreaking for me to see it in that condition too.


If I find some time in between from designing and testing the new projects, I might put it back together and luckily I'll upgrade some parts of it a little more... :yes:

Hi,

Here is an interesting article from our Japanese friends:

Hi Thanos. While planning and building my wersion of Joyrider, I wonder if you or someone else have tried a sim with the frex/scn5 setup, and compared it with Joyrider. Which sim gives the most realistic feeling???

Hi Thanos!!

I decided to start making your project but... your web site with photos and instructions gives 404 error..(((
Its moving to a new hosting?

Here is a link to download my site as file to watch it offline for now:

I cant affort to put it back online at the moment. I'll inform you if anything changes.

Thanks,
Thanos

Hi Thanos!

Tell me please, you connect these sensors directly to the microcontroller, or use an additional amplifier?

Thanks.

No additional amplifier or anything is needed...! These magnetic hall effect sensors are ratiometric and work within the 0-5v range. You can connect directly like a normal potentiometer... you just have to be sure to read the datasheet for the pin outs...

Thank you, Thanos!

Hi Thanos


is this Wipper ok ? http://www.microsofttranslator.com/bv.a ... 0468114331
