  1. The idea seems good, as long as each little wheel is not in contact with the previous and the next one.
  2. This achievement is really great! I dream of another, able to make very large posters with 3 RGB pens. Thank you for all this.
  3. I agree, but here it is with integrated motor speed reducer in output. I'm sure you're right, but I still do not understand. That is my problem. Anyway, thank you for your explanation, I take good notes.
  4. Do you mean that any differences in speed of the two motors can break the gears? One can quite easily turn the axis motors XL, so I thought reciprocal attenuation solved this problem.. I feel that your two solutions are equivalent.
  5. The question I ask myself, regardless of the power problems, is it dangerous for the internal gears of the motors to couple two motors XL to double the power of an specific action ?
  6. Interesting ! Very interesting! Is it possible to go faster?
  7. This interests me a lot ! Regardless of the differential problem, do you think it is not advisable to couple two motors XL, powered from the same battery?
  8. This is very good, but why don't you use the small servos instead of the larges ?
  9. May be, you can try this : http://alpha.bricklink.com/pages/clone/catalogitem.page?P=x1681#T=C
  10. Copy or not copy, this shows that we must not rest on our success and always innovate to not disappear overnight.
  11. I know this stuff, but it's too expensive for the size of my tank. Today, I study non Lego solutions. I advance a bit by eliminating solutions ... It is true that my goal is to climb stairs, not to make a copy of a battle tank. My tank is 1m long. Of course, I will present it here when it's finished.
  12. Thank you for sharing. I do not find the reference of this rubber on Lego shop, can you give it to us please ? Unfortunately, the 14149 of the set 45560 is really expensive.
  13. I think it is exactly the same video. The purpose is to encourage him by clicking on the thumb if you like his video. Well, this is what I understood.
  14. Congratulations for the originality of your creations !
  15. You can try starting from this : http://www.eurobricks.com/forum/index.php?showtopic=114392&hl Good luck !
  16. For me, Legos are a means, not an end. Therefore, I have no any forbidden.
  17. Yes, I noticed the mouse, but at any time, I wondered what you said. But as I said, "If one day I was using this software, your video would certainly be very precious." Thank you again.
  18. A great thanks to you. For occasional use, I find that Blender is very complicated. This is software that requires a large time investment. I watched the video in accelerate. My understanding of English is not very good, too bad you did not put subtitles. If one day I was using this software, your video would certainly be very precious.
  19. Big success! Congratulations ! I use the motor block by indicating the time in seconds, nothing more. I use the LEGO MINDSTORMS Education EV3.
  20. Can you tell us how you do that ?! fantastic ! Of course ! You have to do !
  21. I know your worm, it is so great ! But its orientation is not very common. Maybe a new projet ?
  22. Thank you for all this ! Here the U-joint, https://en.wikipedia.org/wiki/Universal_joint#Equation_of_motion Here the CV joint, https://en.wikipedia.org/wiki/Constant-velocity_joint#Double_Cardan
  23. I presume that the child should be about 20 or 25 kg. How have you estimated the number of necessary servos. I see that there are 14, it's a lot! In my work, here http://www.eurobricks.com/forum/index.php?showtopic=110051&hl=oracid#entry2230918 ,I demonstrate that with a single motor XL, I can move 8 kg. In fact, I tested with large bottles and it is 12 kg. By the following realization, http://www.eurobricks.com/forum/index.php?showtopic=117220&hl=oracid#entry2384354 , I realize that the servos lost their position when the torque is too high,which slows them a lot, for this reason I used the XL motor. Nevertheless, I like your achievement, myself, I'm trying to make a 1m tank, but for now, I do not know where I'm going. Therefore, what you are doing really interests me.
  24. I bow down face so much poetry.
  25. I put this in a corner of my brain. Thank you so much.
