    What do you mean about "Stock controller" ? Do you mean that "Custom controller" is your own PID ?
  2. oracid
    Great ! Really Great !

    Here is a module for connecting 8 servos. But are not LEGO servos which have the advantage of being very powerful and cheap. http://www.mindsensors.com/ev3-and-nxt/25-8-channel-servo-controller-for-nxt-or-ev3

    This is a very great MOC !

    Do you mean you had or you can make a multiplexer like this one ?
  6. oracid
    I love that !

    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.

    My goal was to make a robotic structure based on a tank frame. This tank should be sufficiently large and especially light enough to climb stairs, whatever they are, and even those with nosing. These imposing a great height, see my previous videos. With a length of 85cm and a weight of 2.5kg, I feel I have reached my goal. Furthermore an additional charge of 1kg is possible and will allow additional batteries or any component for a particular application. This 1kg load is a maximum as you can see in my video, it struggles to climb stairs. For the tracks, I used D joint (window joint) as shown in my previous videos. Thank you for your feedback. Settings and detail components with their weight: Length 85cm Width 48cm Height 22cm Chassis Weight 1300g EV3 + 165g battery 122g 4 large servos 82g x 4 = 328g Infrared receiver 20g Cables 44g Track with D joint 272g x 2 = 544g Front tank angle 35°

    Very good idea !
  15. oracid
    Good work !
  16. 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.
  19. 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.
  21. oracid
    Which file ? All your files are .ev3p and I need an .ev3 file to open a project.
  22. oracid
    Hi. Interesting ! Can you explain, step by step, how can I import your MyBlock ? Thank you.
  23. oracid
    Sorry Technic Jim but I do not understand your vehicle. Is a segway? What is its purpose?
  24. oracid
    I love this !

    Thank you for this very good link.
