    Oh yes, I am following this topic, I did not do the link. I am looking forward to the result !

    Very great ! Sorry for the off topic, Can you tell me what is your animation software?
  3. oracid
    I am excited to see what you're doing.

    This is not one of my achievements, but a Hugolin's achievement, who allows me to present his MOC, a braiding machine. Hugolin is a well known french MOCer, unfortunately he does not speak English. I will pass your comments.

    I love that kind of thing !
  6. oracid
    This seems important to me and I am very much interested, but could you tell us more about your goal?
  7. oracid
    So good ! I was wondering. Is this a copy of an existing industrial process or is it in your design?

    Yes, on Mars, maybe it would be nice ...but on Earth, I tried several things like this and it was not very effective, but I study a new principle that I hope you will appreciate, I will come back on this problem. it's a shame that Lego does not make a very big wheel. For robotics, I think Lego should consider a larger scale. I think your point is very important. This bridge-like structure is at the root of the rigidity of the rover.Perhaps you've noticed that I had already used for Porcupine, http://www.eurobricks.com/forum/index.php?showtopic=110044&hl=porcupine

    @PROlego. I understand what you mean now. Don't forget that the main thing is to have enough grip to the ground. I am not shure this piece help much instead of silicone tube. The 1/2 bush are here, not to grip, but to allow sided rotation. This because silicone grip to much and prohibits sided rotation. To understand what I mean, please look at this http://www.thingiverse.com/thing:638687 Thank you WINNER for explanation. @DrJB. Yes, of course, the shock absorbers work very well as you can see in the video. Thank you everybody.

    BIG is ... big! I think if it had been smaller, its capacity would have been lower. I think I understand what you mean. I have tried many solutions but this one seemed the most effective to me. I have another idea which I will speak later for future release.

    Thank you everyone for your enthusiasm. Here are some details. Below you will find images of a wheel. The perimeter of the wheel is constituted by axles 16 coated with a silicone tubing between two ½ Bush. Silicone provides excellent grip to the ground, but prohibits lateral rotation. It is for this reason that I have inserted the Bush ½ yellow wich has a slightly larger diameter, which allows the lateral rotation. Sorry, PROlego, I do not understand your idea. Can you clarify?

    My goal here is to provide a big vehicle for some robotic application. - length 75cm - width 47cm - height 28cm - wheels 27cm - weight 1,750kg

    @OneMoreRobot. You are a beginner, as I can see. @Rockbrick. Thank you, I did not knew that.

    I'm really happy that this turntable is operational in your exhibition. Do you have some pictures to show us ?
  15. oracid
    Put your monitor perpendicular of your eyes direction.
  16. oracid
    That's what I thought. It's really very effective. Thanks for your answer.

    I have done this. To make the pliers, I used a small grinding wheel mounted on a drill. Be careful not to over tighten.
  18. oracid
    Wonderful as usual ! I could spend hours on your site. I saw the pictures. Could I have more details on the torsion bars? Thank you.
  19. oracid
    I love that ! This is a very good work.
  20. oracid
    It's very interesting. Keeping a large size, I think a new faster and lighter version is required. I have no advice to give you, but YouTube is a good source of inspiration.
  21. oracid
    I am very impressed ! Can you give us the size of the wheels and of the crawler ? Can it climb stairs from face and how high the step ?
  22. oracid
    May be this can help you : http://www.eurobricks.com/forum/index.php?showtopic=110051&hl=turntable

    Ok, if yellow is not good I will try blue. But what about the 13 or 15 beams long ?
  24. oracid
    But these are new ones, are'nt they ? I have not seen them before. Could you add 2 of 13 and 2 of 15 ? As the series would be complete. And would it be possible to have them in yellow? I like yellow. My English is not very good. When I say soft, that's the adjective I would use for a tire for example.

    I may agreed with that ! As you can see at about 0'50 of the video, when the crank turn 180°, the motor turn 90°. Yes, I know there are gears in the generator, but as you can see in my video, the torque of my crank is not very high. It is up to each one to evaluate the best torque. And about the gears of the running motor, well ... it is the same as with a battery.
