    the wikipedia article on the RS200 is also quite good.

    it's not based on a racecar - it's a production car under homologation rules meaning the racecar/production car are pretty much the same thing with the exception of some safety related items


  2. Seems a little at odds. To cope with different speeds you'll need to pass both inputs through something like a subtractor and in doing so you'll still have one set of motors fighting the other. The idea of mathematically adding speed + torque doesn't automatically end up with the product of both. Power is already a product of speed and torque; you can't add a high speed low torque high power motor to a low speed high torque motor and expect to get high speed and high torque. At it's extreme with a stalled vehicle, you'll end up with the high torque motor driving the car forwards and the high speed motors backwards. Or you use a spectacularly complicated gearbox with electronic control that will take away the torque you wanted sent to the wheels.

     

    I wish you well, but i'm not sure from your limited description about what you're trying to achieve.


  3. I was under the impression that the 'all brands' stuff was intended to encompass non lego produced lego. ie, genuine lego that had been altered (like chroming for example), or for manufactured parts that lego do not produce (brickarms etc). It was never intended to cover counterfeit/knockoff copies.


  4. In many ways, i believe the reason we see a lot of models of real things is that they capture peoples interests and lead to a desire to recreate it. In terms of new ideas, shapes, techniques and even mechanisms, you've only got to look at the competitions entries to see all of this new stuff. And then there are people like JK(brickworks) coming up with all sorts of new sculpture mechanisms and the GBC creators tend to be good at it too.

    If i'm honest, I think many of the cool mechanisms we see won't have a need in the future. You mention electric vehicles - well those work very well at a huge range of speeds from nothing to flat out just connected straight to the load - no need for 8/10 speed gearboxes or even the holy grail of infinitely variable transmissions are required for example.

     

    A future of simpler (mechanical) engineering is entirely possible by technology disruptors.

    And if someone comes up with a beam-me-up transporter, who's going to be interested in whiz bang cars with heavy mechanisms to make scissor doors any more?

    After all, the reason a geneva mechanism was invented was because they only mechanical control and no electronics or other means of incremental but non physical movement of source data.

    Hope this is of some use. As far as a parts list, I would start with 200 headlight bricks, 50 6x16 plates and 300 1x8 bricks or variations thereof.

    The leading 1x16 bricks across the frame inside the box provide lateral support over the king pin.

    The trailing lateral structure is two stacks of four 2x16 plates between the axles. Longitudinal structure is the traditional technic technic bricks separated by two plates and periodic pinned support between the rails.

     

    Is your cabover a special design of yours or a 5563 body on the 5571 chassis?


  6. Fair points - but you'd be amortising the development value across (hopefully) a horde of people would use, with perhaps the ability to use lego parts where suitable and cheap - for example, using the track links and motors from lego might be a good cost reduction idea for your widget - many of us already have rpi sets we could use, and so on. 

     

    Interesting thought experiment nonetheless :) Congratulations on a great demonstration project anyway. I always found that the hardest part of any development project (particularly software) was showing it to people and having them play with it. A random pile of parts in your case is very different to a carefully selected test sample you built your system around and to see it work is outstanding :)


  7. Wow - this has an obvious (dollar) value to me as an AFOL based purely on my time that i'd rather spend on building than sorting, and i'm sure every bricklink type store who takes in piles of used stuff would find it economically useful as well. 

    It's also brilliantly geeky to build it out of lego in a serpent eating its own tail kind of way, but perhaps you might angle toward some kind of crowd sourced manufacturing implementation of this. A brick built shaker table would fall apart in short order and isn't necessary for a production version - same with the bins. But the potential is huge! You could even provide a common data set for updating users entities with improved AI  datasets, or choose to license it.

    Sounds like with your 18 bins, it would be fairly simple to broad sort element types, then keep refining - one bin becomes 18 recursively until you've got unique part types - or ultimately even part type and colour if you want to go that deep down the hole. :)


  8. I'm not sure I understand the angst with taking over BL with regard to uncovering a new data source for selling stuff, be it reissues of sets or working out what parts afols want or what's rare - the 6 month sales data is publicly available. Nothing stopping a company this size from employing someone to trawl the sales data looking for patterns if that's what you want. Personally I think it's definately not the reason TLG wanted to take ownership of it. On top of that, for rarity etc, the price guide is also public with an API
