    Very beautiful, the minifigures are a great touch.

    The colour combination is very nice. You have some very nice details too, like the ventilation flaps and the well finished interior. Nice job.

    Yup, saw it now. I was interested in the grippers and the base, the pictures you have are more than sufficient. Apologies for asking for info you had already provided, I was very excited by this project and obviously missed some stuff.

    Thanks for the extra pictures, I never thought you'd take my words so seriously. I enjoyed the pictures in your previous threads, and figured you were having too much fun with this build to take pictures. Nice work on the seats, they look really good.

    I was going to bring up the same point. While a lot of parts can't be made with thinner walls (studded bricks, for example), other parts have seen an evolution in wall thickness. All the pins made now have much thinner walls than their equivalents from 20 years ago. They break easier, but I don't have any tooth marks on them so they are easier to play with. At the same time, 1L bushes and u joints are much less prone to cracking, despite little change in the design. From what I can tell, the plastic being used today is just as good (if not better) as the old one, but there is less of it used. It results in thinner and better designed parts that still fail, but are a lot more enjoyable to play with. A big improvement has also been made in the fit between parts. It seems like tolerances have been tightened to give a much more consistent feel when working with the same parts. All the pins of one type require the same amount of force to put in, same with gears sliding on an axle, and so on. Gone are the days where an 8 tooth gear would be permanently fused to a 2L gray axle pin. It makes building much more enjoyable.

    Thank you, this is what happens when I post before having my morning coffee.

    Thank you for the kind words everyone, I really appreciate it.

    Fascinating project. Thanks for the detailed description of the development. It really shows how much effort went into this. The camera calibration workaround (ball on string) is really clever. Now a few questions: Is the processing done completely by the EV3 unit? (I think the answer is yes since you mentioned processing times). How far away can the cameras track the ball? What is the success rate for catching the ball? It looks like the accuracy of the throw and the incoming speed play a big role in the ability to catch the ball, so maybe it varies from person to person. Last question is more of a request - would you be able to post a few pictures showing the details of this awesome robot?

    Excellent details. What happens to this model after the expo?

    I turned a Race Kart into a Cement Mixer. This C-Model for the Lego Technic set 42048 has the following functions, best seen in the video below: Steering Internal mixer External mixer Fake engine Neutral gear Parking brake Cement spreading pipe The lack of bevel gears in this set made perpendicular power transfer virtually impossible. The mixer is powered at an angle but the 8 tooth gear has to be placed properly for it to work. It doesn't slip, but it's not my favorite way to build. There are also at least two illegal connections: the steering axle is slightly angled and the parking brake is made by applying pressure to one of the red gears. Both functions work, but hacks like this put unnecessary stress on parts that is not desired in the long run. Left over parts:

    Grum, I was hoping to see pictures of more stages of the build, but you are putting this model together too quickly. Please slow down. Or at least take more pictures so Blakbird isn't forced to provide any more content for this topic.

    I believe your method is called admirable masochism. In all honesty, I'm not sure if building a digital copy would be any faster than what you are currently doing. Your method obviously works and gives great results.
  13. BusterHaus
    Beautiful airplane, the tail is very well done.
  14. BusterHaus
    It's growing big now! I'm guessing you built a digital version first? How long did that take?
  15. BusterHaus
    A very cute truck, it looks like it could make a nice official set.
  16. BusterHaus
    It's nice that you are giving us a peek at the inside. Is there no bottom to the hull?

    I'm building a pneumatic biped for the contest as well, although my mechanism is quite different. Are you shifting the center of gravity on the body, or just on the legs?
  18. BusterHaus
    The IR receiver would only control when the pump motor runs. The functions are still pneumatic and only happen while the pump is running. I'll wait for an official answer to this.
  19. BusterHaus
    Are IR receivers allowed to control pumps?

    Nice idea, but since the wheels rotate at different speeds in a turn, I would expect the 20 tooth tan gears to be misaligned when the two 12 tooth black gears (attached to the gear rack) come back into place. Looks like a recipe for grinding gears, unless I'm missing something.

    Very sweet renders as usual, they showcase the model well. The writeup is well done, too, although I would have liked a section for impressions or opinions (I know they were included within the text). Job well done. Are you planning on reviewing the B model?
  22. BusterHaus
    That joystick looks very good. I really like that the friction of the switches gives it some resistance, so it doesn't just flop around.
  23. BusterHaus
    Very well done, it looks like he could be drag racing with this wheelchair.
  24. BusterHaus
    This is going to be very fun to watch. The joystick is where the magic will happen.
  25. BusterHaus
    Looks very good! I love the lights, they really make the model look realistic.
