    Good thinking, but I think we can do better with that, http://www.mindsensors.com/ev3-and-nxt/21-multiplexer-for-nxtev3-motors May be one day, I will do that.

    I think it would be too heavy. I already made a version with 8 XL motors, unfortunately it is also too heavy and quite complicated. Good question ! I hesitated because I would not disappoint. I am looking for a domain where I could bring my stone.

    If I made a tank of this size, it is for him to climb any type of staircase and not specifically to make it big. My goal was to show people interested in robotics, it is possible to make a real climber with few resources. Like everyone else, I read the book of Sariel, but if you have a schematic showing me how to use 8 servos with EV3, I will like to know how. I do not think I will go further in this domain. My goal is reached.

    Yes of course, the power can be increased by reducing the speed, it's a choice. We can do it with some more gears or use a smaller sprocket, but I do not know if it works, I've never tried, I do not have it, http://www.bricklink.com/v2/catalog/catalogitem.page?P=57520&name=Technic%20Tread%20Sprocket%20Wheel%20Small&category=%5BWheel%5D#T=C For the size, I think if there were larger beams sizes this could solve the gamme (may be not the good word, sorry) tied to the number of parts. Thank you for those excellent remarks.

    I am not sure to understand. You can see the tank going down, but backward, at 0'58. Yes, it can going down forward. But not easy to make short video and to show everything. I don't think the problem is the plastic, but servo power.

    Very good idea !
  8. oracid
    Good work !
  9. oracid
    I fully agree with you!

    The goal of Jim is very different, but if you're interested, I invite you to look at this: http://www.eurobricks.com/forum/index.php?showtopic=119844&hl=climber The suspension for a robot, it's a real discussion ! I think if the goal is to consume less energy, it can be interesting, but if set for user comfort as in a car, and there, there is no user...

    This seems very interesting, I will follow this topic very closely.
  12. oracid
    Good idea ! I like that.

    You have to know that your file is a .zip file not an .ev3 file. So, I have changed the subfix to .ev3 and now it is good. Ok, I will have a look to your program. Thank you.
  14. oracid
    Which file ? All your files are .ev3p and I need an .ev3 file to open a project.
  15. oracid
    Hi. Interesting ! Can you explain, step by step, how can I import your MyBlock ? Thank you.
  16. oracid
    Sorry Technic Jim but I do not understand your vehicle. Is a segway? What is its purpose?
  17. oracid
    I love this !

    Thank you for this very good link.

    I have got a 3D printer to create original pieces. This is a French printer, the Dagoma Discovery200. This printer cost 400 € and is at the moment very popular in France. My goal is to show that we can produce parts of acceptable quality for a very low cost. For example, below small parts cost about € 0.06 and large about € 0.25 My pieces do not satisfy me completely, but as soon as possible, I'll post them on http://www.thingiverse.com/ At the moment, 3D printed parts absolutely not rival those of origin. Nevertheless, an overall movement can create impulse that would make LEGO to increase and supplement its offer. But I do not doubt that in a few years the quality will be there. I think we have already to be prepared. In the world of robotics, the one that interests me, we cannot wait. Robotics revolution has already begun. Here I show you parts used for assembly, not for torque.

    I have already ordered NinjaFlex. I am waiting for it. The PolyFlex will be useful for making flexible beams, shame he's black. For the overlaps of the edge I think I understand what you mean but can you be more specific. I can reduce the recovery but not much. Have you a better idea?
  21. oracid
    I have printed my first track shoe. Here is the result. I'm not really satisfied because the PolyFlex is quite slippery and has not the effectiveness of the window joint. The weight is 1.5 g. I'll try to make it thinnest.

    Here is a shoe draft for LEGO track link.
  23. oracid
    Thank you Tommy for sanding 123D files, that is far better than stl. I will recevied my Flex thread very soon, I hope To day, I will try to make a draft of my Flex track part. So you can see.

    Here is my 3D printer, http://www.dagoma.fr/en/produit/imprimante-discovery200/ The material I use is the PLA, http://www.dagoma.fr/en/categorie-produit/fil/octofiber/ My 3D printer is very basic and uses the FDM technology. My software is 123D Design, http://www.123dapp.com/design What I want to show is that today we can print his parts at home with his printer for a very low cost. Parts quality is not excellent, but things will get better quickly. @ Driftworks..I think what makes the quality of a printer is first precision. @ Kelkschiz. It is the printer software, CuraByDagoma who determines the price of the parts based on the price of the thread. The purchase of the printer, working hours and electricity costs are not taken into account. @Tommy Styrvoky. Yes, I'll probably quickly make rubber pads for LEGO tracks, and perhaps new track elements. This is my priority. I am waiting for rubber thread. Thank you for your files, I will study them. @dr_spock. What do you mean by "local public library"
  25. oracid
    I know the Efferman parts of course and I already ordered somes. Their design and quality are very good. My approach is different because as indicated by the title of this thread, I make the parts myself, at home, with my printer. The quality is lower, but the cost is significantly lower.
